Inkjet printers are convenient and efficient printing devices. Due to their low cost, they have become publicly available. However, one should not think that equipment manufacturers set minimum prices for noble reasons. The main income is generated from the sale of consumables, which include replacement cartridges. Their price can be 30-60% of the cost of the printer. It is quite natural that users ask reasonable questions: what is needed to refill cartridges and is it possible to do without regularly purchasing them?
A printer has been created in South Korea that can do without a cartridge or ink at all. For its operation, only the Sun is needed, since the device operates using its energy, and the resulting images are not printed, but burned.
Basic savings options
There are three main options for saving on ink for inkjet printers:
- Purchasing non-original cartridges. They are indeed cheaper, but can cause printer failure.
- Use of refillable cartridges. Not a bad option, but you will have to resort to frequent manual refueling.
- Installation of CISS.
What is CISS
CISS is an abbreviation that stands for continuous ink supply system. It supplies ink to the print head from special refillable reservoirs. The CISS includes ink containers and a silicone cable with which they are connected to cartridges or capsules. Depending on this, a distinction is made between cartridge and capsule CISS.
In the first case, cartridges are used that are identical to the original ones, but are not equipped with a chip that reports the lack of ink. In the second, transparent capsules are used, installed on the input needles of the print head. The main requirement for both systems is tightness. While the printer is running, the amount of ink in the cartridges or capsules decreases. As a result, under the influence of excess pressure, paint begins to flow from the CISS containers. When installing them, you should follow the rule: the bottom of the tanks should be no more than 1-2 cm below the level of the print head nozzles.
Advantages of using CISS
The practical application of a continuous ink supply system provides a number of significant advantages to users:
- First of all, it should be noted the possibility of tangible savings in material resources. For example: when using inexpensive, popular color inkjet models Canon printers CISS allows you to reduce costs by 50 times even when purchasing the highest quality ink.
- The absence of the need to frequently change the cartridge minimizes the risk of head damage due to air getting into it.
- You can use ink of any color suitable for a particular occasion.
- Quite labor-intensive operations of replacing and especially refilling cartridges are eliminated.
- The operation of replenishing ink in containers is greatly simplified.
- It becomes possible to print large volumes of documents or images without stopping.
- The environment is not polluted by used cartridges.
Disadvantages of CISS
- The cost of CISS exceeds that of refillable cartridges.
- You must purchase the system separately from the printer.
- Installation of CISS requires care and precision.
- We can talk about a certain unaestheticness of ink containers near the printer.
- The use of CISS is considered a re-equipment of equipment, therefore manufacturers refuse warranty obligations.
- Rearranging or moving the printer becomes quite a complex procedure.
- In case of prolonged inactivity, the ink may dry out in the silicone cable, which will necessitate the need to replace the head. This disadvantage can be called conditional. Prolonged downtime in any case entails drying out of the ink.
When choosing a refill system, it is important not only to know what a CISS for a printer is, but also to soberly weigh all its advantages and disadvantages. Only with this approach will it become a means of effective savings.
CISS is a continuous ink supply system. It allows you to forget about small-volume disposable cartridges, which are traditionally used in printing devices and which have to be changed frequently, spending quite a lot of money. In contrast, CISS consists of large ink containers (usually 100 ml of ink of each color), which are economical in consumption and can be refilled multiple times.
Installation of CISS: instructions and useful tips
Owners of inkjet printers who do a lot of printing at home or at work have probably heard a lot about CISS. True, not everyone fully understands what it is and how it works, so in this article we will try not only to clearly talk about the new device, but also to explain how to install it.
Basic operating rules can be seen in this video
Types of CFC systems and their characteristics
When you decide to buy a continuous ink supply system and are looking for suitable options, you will see that it comes in two types:
- Standalone is a stand-alone device that is suitable for most models of MFPs and printers famous brands. You can purchase it separately and install it yourself or contact a specialist.
- Built-in - a system that is sold complete with printing devices that are designed for full-color printing for commercial purposes. The leader in the world of built CISS on this moment is the Epson company with the “Print Factory” line. In addition to all the advantages of the “factory” CISS, there is one very important drawback- price. The cost of printers and multifunctional devices with this system can be 2 or 3 times higher compared to similar models with an autonomous CISS.
Noting the advantages of CISS, it is worth saying that it is not connected, like cartridges, to the print head of printers, so you can always access it and add ink desired color possible when the need arises - even during printing, which will guarantee its uninterrupted operation. It is also important to say that this modern system it is ergonomic, which means it does not take up much space and is convenient to place - some models are a block that can be installed even remotely from the printer so that it does not take up space on the desktop. However, with such an installation, it is important that the system is on the same level as the MFP, since otherwise the ink may simply leak into the printing device and stain your favorite table/carpet/sofa.
Trusted manufacturers
Having bought a cheap CISS made in China, you may be faced with the fact that you will receive a box with many containers, tubes and incomprehensible parts that will take a long time to deal with. We recommend spending money only on systems from trusted manufacturers, because in this case you will be confident in the quality of the product and in the fact that it comes with instructions, which will make it easier to assemble and install. Of course, you can try to install it yourself by downloading the manual on the Internet. Only in this case, there is a fear that during connection the air exchange system of the bypass valve will be disrupted, and the CISS will not be able to work.
Ideal if you order printing device, which comes with a CISS system, for example, MFPs such as Epson XP-330 or Epson XP-342, then you do not risk anything and will be confident in its normal functioning. The second option is to buy the printer from one company and the system from another place. This way you save 3-5% of the total cost, but you completely lose the warranty on the printing device, since no one will want to service third-party CISS. Therefore, we do not recommend this option to you and recommend that you buy everything as a whole.
Self-installation
If you are used to doing everything yourself and set about installing the CISS yourself, then just take the instructions and follow everything that is written there:
- Use tubes to connect the containers to the cartridges.
- Fill the cartridges with ink.
- Open the bypass valve to remove air from the containers.
The main thing to remember is to control the ink level and under no circumstances allow air to get into the print head. If this happens, contact service center can't be avoided.
Problems you may encounter
When purchasing CISS from unverified suppliers and manufacturers, you may encounter the fact that it will not work correctly. Most often, users note that the principle of communicating vessels is violated and in order to pump ink into the cartridge, the container with a continuous ink supply system must be raised high. In addition, the CISS may not be suitable for your printer model at all, so carefully study the list of devices with which it is compatible. Do not forget that the device must include instructions, this will guarantee that you have purchased a quality product.
CISS is, of course, very profitable and will reduce your printing costs, so there is no need to doubt the advisability of purchasing it, just approach this issue responsibly.
CISS is an abbreviation for “continuous ink supply system” in inkjet printing devices (printers). This, at first glance, is a complex design with several containers and tubes that are connected to cartridges. It allows you to perform tasks of any level of complexity, print large quantities of documents, drawings or illustrations without changing cartridges. Now you don’t have to worry that your inkjet printer won’t be able to print at the most critical moment.
CISS device
The main elements of this system are special containers with ink, which are called donors, an elastic cable and an autochip system.
In fact, the main operating principle of the entire system is Mariotte's law, due to which ink is passed through the printing unit under constant pressure. This makes it possible to produce a uniform flow of ink, regardless of the amount of ink. This is one of the most important principles continuous printing, allowing you to obtain a high-quality image at the output.
The train itself consists of several tubes with ink of different colors. They feed them into the print head. Depending on the type of containers (dampers, cartridges or capsules), printers with CISS are also divided, i.e. capsule or cartridge.
The autochip, which is equipped with all CISS models, contains important information about the remaining ink and its correspondence to the original. Essentially, the printer processor receives a signal that the device can operate because a new cartridge is installed. This is an elegant way to “deceive” the printer, which is configured in such a way as to block printing when the cartridge is not yet empty (a certain percentage of ink remains, but the printer already gives a signal that the cartridge needs to be replaced).
Thus, the CISS device is a system of communicating vessels, which ensures high-quality and continuous printing.
Advantages and disadvantages
The main advantages of this system include the following:
- obvious savings in consumables: you no longer need to frantically search for original cartridges or risk refilling ink that is already empty;
- ensuring a continuous printing process: this is especially important for large companies that have to constantly print documentation, projects and illustrations;
- Extending the life of the printer: thanks to this system, the print head of the printer does not dry out, which is usually fatal for inkjet devices;
- saving time and money.
The disadvantages of CISS include the system’s demandingness regarding the position of the containers (they must be located vertically). If positioned incorrectly, ink may leak. Also, colors cannot be mixed (as in a conventional inkjet printer, where black, red, blue and yellow colors are supplied in separate containers). It is also important that optimal pressure is maintained inside the system for continuous ink movement, so the CISS must be installed in line with the printer. In principle, there are no particular difficulties with installing such a system. Moreover, manufacturers note the simplicity and ease of maintenance, which make it easy to refill containers with ink.
It should be remembered that the system may fail if there is no ink, so you need to monitor this. However, modern CISS are designed for a long service life (printing up to 12,000 sheets), so a basic set of containers and ink lasts from 12 to 36 months, depending on the intensity of printing.
How beneficial is it?
How to install CISS
If the CISS device operates correctly, your printer will last a long time, delighting you with print quality.
What is CISS
Something like an intro
A man bought a printer, prints texts, drawings, photographs, everything is fine only from time to time, from time to time he has to replace the cartridges with new ones.
There comes a time when changing or refilling cartridges gets boring, especially when there is a large volume of printing - just started printing - the cartridge runs out.
That’s when you start to think about how to attach a bottle of ink to it (the printer) and forget about changing cartridges.
Continuous feed systems were first used in 1993-94 in NovaJet plotters from EnCad. It consisted of 500 ml ink cans, which were connected through tubes to inkjet heads (this principle has been preserved to this day).
CISS is a system of communicating vessels designed to receive ink as it is consumed into printer cartridges from donor containers.
Ink is supplied through elastic tubes (a kind of cable) connecting the printer cartridges and ink containers. Due to the created vacuum in the cartridge chamber, the ink from the tubes fills the space of the ink spit out during the printing process.
Printers are available with a built-in PG (print head) and with a PG located on the cartridge.
Typically, CISS is desirable and more expedient to use in inkjet printers with a built-in print head, this is due, first of all, to the high resource of the head, although in principle, CISS can also be installed on a printer with a PG located on a cartridge. (By the way, I installed my first CISS on a printer with a cartridge with a built-in PG).
What else positive can be said about CISS?
Let's start with the printer's performance, which is determined not only by the printing speed, but also by the complexity of the technological operations for changing the cartridge or refilling ink, as well as the percentage of defects as a result of the end of ink in the cartridges during the printing process. If you do not have a continuous ink supply system, then the ink in the cartridge will sooner or later run out and it will have to be replaced. At the same time, depending on the type of printer with a new cartridge, you have to perform various technological exercises for cleaning and adjustment, which can take 10-15 minutes (and sometimes more if the new cartridge turns out to be defective). Next, keep in mind that you have several cartridges installed on your printer (or one with several chambers) with different colors and that they run out at different times. Therefore, in the case of several color cartridges, they will have to be changed several times more often, and with one color cartridge with several cameras, you will also have to throw it away with unspent ink (unless, of course, you refill the cartridge yourself). Thus, the average printing time per page and, most importantly, the cost increase significantly. Needless to say, all these problems can be avoided by using a printer with continuous ink supply (CISS). This will allow you to increase the performance of your system by 15-20%, all other things being equal.
This system is also of great importance for reducing operating costs. Firstly, ink for such systems is 3-5 times cheaper than ink in cartridges. Secondly, defects due to ink running out during the printing process can be avoided.
Thus, the use of a continuous ink supply system can significantly increase productivity and reduce operating costs, reduce printing costs several times and improve the overall quality of work.
In a number of cases, during the manufacture of CISS, the technical drainage of ink into the diaper (absorbent sponge) of the printer is converted into drainage into a separate container.
During standard operation, the printer counts the number of pages printed and the number of technical cleanings - which are necessary for normal operation printer. Technical cleaning is carried out by the printer itself according to the programmed program + cleaning performed by the user. Once the required amount of data has accumulated, the printer stops working until the diaper is reset.
When draining the drain into a separate container, the diaper with “certain literacy” can be reset manually and continue operating the printer with CISS. But this is a separate question.
Well, now you can go directly to the CISS itself
There is nothing complicated, much less tricky, in making CISS; the main thing is to understand the operating principle.
Having understood the principle of operation, you can independently manufacture and install CISS on the printer, and this will not be difficult.
There are people on the forum who can assemble CISS from scrap materials, and, what is most surprising, all these CISS will work perfectly.
It seems to me that if Yukha ends up on a desert island, he will find something to make CISS out of there too.
Seems distracted.
How can you install CISS on the printer?
In my opinion, there are two ways:
1. Order a CISS in the RESETTERS store, and following the instructions (which are attached) install it (the CISS) on your printer.
2. Order from the resetters store something that is difficult to make at home (chips, cable) and make the rest yourself. By the way, with a certain skill and experience, you can also make a train yourself.
So, what does CISS consist of?
1. Donors - containers in which ink is located.
2. Loop – through which ink flows from donors to cartridges, capsules, damper chambers and further to the PG.
3. Cartridges, capsules, damper chambers.
Chapter I Donors - containers
Donors are containers in which ink is located and, as needed, goes to the PG.
In the very first CISS, 200 ml were used as donors. ink bottles, a hole was made in the lid for a tube that went down to the bottom, and an air filter was placed in the lid there.
Subsequently, such donors were abandoned, since the rate of ink flow out of such bottles is different and depends on the amount of ink.
Although 200 ml. Ink bottles continued to be used, adding a hydrodonor based on a cap from “GALA” (dishwashing liquid).
The result is a kind of Mariotte vessel, where the flow rate of the liquid constant and does not depend on the amount of ink in the donor. 
Rice. 02 
Rice. 03
Now we need to tell you a little about the Mariotte vessel, its principle of operation.
Well, now let’s look at how a donor made according to the principle of a Mariotte vessel works.
I think it would be correct if we divide this issue into several stages.
1. filling the donor and its work.
2. how to reconcile or balance the donor and PG.
How to properly fill the donor and its work.
Rice. 09
1 – compartment where the ink is located.
2 – air compartment.
3 – tube through which ink flows from the donor to the PG.
4 – hole for filling the donor with ink.
5 – plug for the air compartment.
I would advise that before filling the donor with ink, check it for leaks, regardless of whether you bought the donor or made it yourself. If the donor is not sealed, it will not work, so it is better to immediately make sure that it is sealed.
There are many different donor designs on the market, but the principle of operation is the same.
Many people buy ready-made CISS, and some manufacturers’ instructions say that it is necessary to equalize the ink levels in the large and small compartments. This is a deeply erroneous statement, since when leveling the levels in the compartments, your donor will not work according to the principle of a Moriott vessel, but will work like a regular container - “a bottle with a straw to the bottom” Fig. 01.
I want to say right away that there should be ink in the large (ink) compartment, and ONLY AIR in the small (air) compartment.
So how do you properly prime a donor?
For example, consider the donor circuit in Fig. 09.
As I already said, for the donor to work, there should be no ink in the air compartment; for this, before you start filling the donor with ink through hole 4, you need to close the air compartment 2 with a plug 5. This is necessary so that the air compartment does not fill up during refilling ink. After filling the donor with ink (compartment 1), tightly close the filler hole 4 with the plug and open the plug 5 in the air compartment 2. I repeat again, there should be no ink in the air compartment 2. If, after some time, ink appears in air compartment 2, it means that air is leaking into compartment 1.
This may happen because the filler hole 4 is not tightly closed, or if the donor was made independently, the seams are poorly taped. But if we previously checked it for leaks, then there is only one reason - the ink compartment plug is not tightly closed.
Close the ink cap tightly and pump out the ink from air compartment 2.
To do this, take a 10 - 20 ml syringe. connect it using a piece of tube from the dropper with fitting (fitting) 6 for the ink outlet from the donor and carefully begin to pull out the syringe piston, the syringe will begin to fill with ink, and the ink level in the air compartment will decrease.
Use a syringe to completely pump out the ink from the air compartment. As soon as the air compartment is empty of ink, you will notice this immediately, as air from the air compartment will begin to flow into ink compartment 1.
It will be seen how air in the form of bubbles from compartment 2 enters compartment 1. The donor is working.
Disconnect the syringe with the tube from the outlet and leave the donor alone for several hours, while observing whether ink appears in the air compartment.
There is also another way to free the air compartment from ink. I wanted to write, but I remembered that I already mentioned this method on the Episode forum, so I decided to find it.
To make Episode’s advice/answer more clear, I’ll explain the essence of the question.
The person complains about a bad seal, although he installed the purchased CISS, as he writes, exactly according to the instructions and provides a photo of the instructions and a photo of filled donors as proof.
Here is Episode's response in full:
“About the ink levels in your donors.
1. Burn it, throw it out the window, give it to a neighbor, or, as a last resort, eat your instructions for the CISS.
Another option is to send it back to the CISS seller as a token of gratitude.
2. Head in the parking lot. You open the cap on the ink compartment. The ink levels in the compartments are equalized. You take a 50 cc syringe, if you don’t have one, then a tube: one end in your mouth, the other sealed into the hole in the AIR compartment.
Blow until all the ink goes into the ink compartment. Close the ink compartment with a stopper. All. You don't have to blow. As a result, you should have in the ink compartment no more than 90% ink, no less than 10% air. In the air compartment There SHOULD NOT be any ink. AT ALL!
There is another option. Tilt the donors, and thus move the ink from the small air compartment to the large ink compartment. Choose which one is easier for you.
3. Always, I emphasize, there should always be only air in the air compartment, and not an ounce of ink. The presence of ink in the air compartment indicates that the CISS is not sealed, or that it has not been refilled correctly.
4. In the ink compartment, the ink level should not be allowed to drop below 20-25% of the total volume.
Only if all these conditions are met can one try to obtain high-quality printing and stable work of CISS donors.
If these conditions are met, then it will be possible to look for the cause of your stripes in the photos.”
If you made the donor yourself and have little experience in using the donor, then I advise you to carry out all these tests with water, since the chances of getting stained with ink from head to toe are almost zero.
In some donor designs, when refilling them with ink, the air compartment is not visible, since it is located inside the ink compartment. So how do you know how a donor works?
If our donor works like a Mariotte vessel, then during the printing process air bubbles appear in the donor in the large (ink) compartment and you can hear them “gurgling”. This air from the small (air) compartment enters the ink compartment, replacing the ink used for printing. This is especially noticeable when the printer prints for 20–30 minutes.
If this does not happen, then your donor is “an ordinary bottle with a straw to the bottom,” and you must urgently remove the ink from the air compartment.
Donor in Fig. 09 is also convenient because you can refuel it almost at any time, you just have to close the air compartment with a plug, open the refueling hole 4 and calmly refuel. Next, close hole 4 with a plug and open the air compartment. That's it, the donor is ready to continue working. The inconvenience is that when the donor is fully refilled, the air compartment is not visible and you only have to guess whether the ink got there or not.
The situation is different with the donor in Fig. 08, I refill it when the ink is almost out, because when refilling, ink appears in the air compartment, and as mentioned above, if there is ink in the air compartment, the donor, like a Mariotte vessel, will not work.
Then you need to disconnect the cable from the cartridge and use a syringe to pump out the ink from the donor until the air compartment is free of ink (until the air “gurgles” in the ink compartment).
In general, with refueling and refueling of the donor Fig. 08, a lot of “headaches”, but I’m already used to it, although I like the collapsible donors from resetters better.
There is a misconception that there should still be ink in the air compartment, albeit in a minimal amount. And if they are not present at all in the small (air) compartment, then the system is supposedly faulty. I will repeat this erroneous opinion once again. And the complete absence of ink in the air compartment only indicates that the donor design is correctly balanced. And lucky is the one who has such a donor.
The presence or absence of a minimum amount of ink in the small (air) compartment is determined by the design of the donor and depends on many factors, including atmospheric pressure.
When there is even a minimum amount of ink in the air compartment - 2-3-4-5mm.
we turn on the printer to print until it (the printer) uses up these 2-3-4-5mm. ink, the donor as a Mariotte vessel does not work, but will start working only after there is 0 (zero) mm in the air compartment. ink.
Well, that's another question.
Let's take stock
1. In a fully and correctly filled donor, in a small (air) compartment there should be no ink.
2. In the large (ink) compartment, there should be 80 - 90% ink and naturally 20 - 10% air
3. If there are still 2-3mm in the air compartment. ink - no big deal, they can also appear or disappear with changes in atmospheric pressure.
You can fill in any color instead of any other (if the ink type is suitable), the printer doesn’t care. If you confuse Magenta and LightMagenta, the printer will not notice. You will notice.
You can fill all donors with black. You can fill different shades of gray to print black and white photos.
Color rendering will be entirely up to you.
And some colors may differ in properties (fluidity, density, viscosity,...), i.e. clog the PG print head more than others.
It also happens that part of the color of one manufacturer is filled in, part of another.
It happens less often that one type of black is poured - pigment ( if the printer allows
), the rest are water soluble. Or vice versa.
Decide for yourself, if unsuccessful, flush the PG and buy new printer To you.
4. Manufacturer and brand of ink available in your region.
Real guarantee of compatibility of alternative inks with original ones NO. One chemical is precisely known ink composition is different. There are cases precipitation
in some inks, which may cause fatal print head clogged PG. The ink should not contain air, so it is not recommended to shake it, much less turn it into “carbonation” with vigorous refilling from a syringe.
However for pigment On the contrary, there is advice to stir the ink periodically, since the pigment tends to settle to the bottom.
In short, JBond's recipe is "mix but don't shake"...
5. Manufacturer and brand of paper available in your region
6. Any feedback on the print quality of your Printer + Ink + Paper combination?
The printing result greatly depends on the amount of Printer + Ink + Paper
In some cases, achieve normal and good results It is possible only by calibration (profiling).

8. What chips are included in the CISS.
... Ordinary, as on the originals (hardly nowadays)
... Autochips are separate for each cartridge
... SCSI chip (one or connected with dummies)
... One original cartridge is connected
What's happened
So, ordinary chips that are reset by a resetter, and autochips that reset themselves, are subject to fan cleaning. CISS on cartridges has a greater chance of getting chips with fan-shaped cleaning.
9. What ink containers are included in the CISS
Most containers (donors) are made in China, some may leak.
Implementation options:
... Without stabilization (jars)
...
Most modern donors are manufactured with a Mariotte vessel (stabilization device).
All donors with stabilization can work with “disabled” stabilization, i.e. in jar mode.
If, in addition to the main one - the ink compartment (ICH), donors also have an air compartment (IA), then they are intended for stabilization.
Without VO, donors only work like jars.
Prepare
... Tweezers
... Blunt nose scissors cut drip and tape
... Paper clips, paper or clothes pins, or clips
... Hair dryer
... A clean dusting cloth
... A place to work that is not afraid of spills of ink, water, etc. liquids
... A strip from a plastic bottle (preferably straight) to support the soft train
... Stationery tape for attaching the strip to the cable
1. My printer is absolutely new, is it worth installing “original” cartridges or straight CISS?
It is not necessary to put it, but it is possible.
If you don’t install it, you don’t need to flush the PG.
If you install it, you can make sure that the printer itself is working and there are defects.
Very preferably done on original cartridges
. You will see that:
* printer is working
* the printer prints with all nozzles
* what colors on the print have shades
* prepare a control test for comparison in the future
Moreover, it is advisable to do in advance not only the standard test, but also extended tests from other programs (AP, BRS-Test,..) Links to the programs are in the rubricator
Total.
My choice is to set and rinse.
2. Is it necessary to wash the PG before installation of CISS or not (or does it depend on the answer to question 1)?
We carefully read at the beginning of CISS SELECTION about the types of ink and the problem of washing.
My choice is always to rinse! It will take a little time, it will protect you from hemorrhoids... Cost of error = cost of printer.
3. Is it necessary to check the CISS in any way before installation?
Not necessarily, HOWEVER, VERY VERY healthy.
During storage, donors and other CISS parts could collect dust and debris!
.
Do you really want to pour this garbage into the printer's head along with ink?
Donors and plume joints may leak or leak air!
.
You'll be tired of dealing with streaks in your photos.
* Depending on your type of ink, fill the donors with distillation or MM BEFORE connecting.
* Check the joints of the cable and fittings visually and by shaking the syringe, the liquid should not protrude, bubbles should not appear inside near the joints!
*Chip check + simultaneous flushing:
... We inspect the CHIP (cartridges with chips) everything should be neat, smooth and even, without flash, rags, burrs and other unnecessary protruding parts. However, do not be too quick to saw the outside sides; the strip may begin to fall out or will not fall on the contact pads. Without fanaticism!
...
... According to the instructions, we install the CHIP (before laying the cable). With cartridge CISS the number is there, but it won’t work.
... We cut pieces of 1.5-2 cm from the dropper according to the number of printer colors.
... We put it on the nozzles of the syringes, pull the pistons out of the syringes and put them on the fittings instead of the cartridges.
... We make sure that the syringes will not touch the stationary parts of the printer; if in doubt, we shorten the syringes by cutting them or tilt them slightly
... Fill the syringes with washing liquid as much as possible
... Turn on the printer and watch how the flushing leaves the syringes (the printer has turned on standard cleaning)
... The printer is not ready to print, check the error code according to the printer instructions. Usually - no ink.
If the chip has a button, initialize it CAREFULLY according to the instructions
If the CHIP does not have a button, then turn off the printer and install the chip again.
And we study chip problems on the forum.
... When the printer has calmed down and is ready to print, add rinse to the syringes
... We start regular cleaning, adding flushing in a timely manner, then
... We insert the paper into the tray and print the photos until traces of ink appear on the paper. After 1-2 prints, top up.
... now we print black text, because... When printing in color, black may NOT be CONSUMED at all.
4. Is it enough to follow the installation instructions for the CISS or do you need to “finish it with a file”?
It depends. For the most part, the components of all CISS are Chinese.
See previous checks
5. Is CISS adjustment necessary? Isn't it enough to just plug in a unit of cartridges and pour ink into the cans?
If you have read the topic “What is CISS” from the beginning, then you already know...
If not yet, too bad. . This is the key concept!
The quality of balancing determines the accuracy of ink supply to the head.
Poor balancing leads to streaks, blots and misprints.
Configuration is required, required, and may be required again. Regardless of the type of system installed.
Since balancing can change when significant factors change: the amount of ink in the donor, temperature and pressure. Those. Balancing may change during printing and when idle!
Marriott's rake No. 1 - "fountain"
For normal operation of Marriotts, the ink compartment must be isolated from the atmosphere; insulation is achieved using a water seal (“ink seal”).
As ink is consumed, air bubbles are drawn into the ink compartment from the air compartment to compensate for the loss of ink volume.
Due to the presence of air isolated from the atmosphere, Marriotts are very sensitive to the temperature and pressure of the air in the room (atmosphere), as well as the heating of the donor (the air in the emergency room).
As a result of a drop in pressure in the room or when the air in the CHO is heated, the air in the ink compartment expands and pushes the ink into the air compartment (AC).
Essentially, VO is an expansion tank for ink.
Typically, the air compartment has a small volume and an even smaller horizontal cross-sectional area.
If the VO cannot accommodate all the ink being ejected, it will cause it to spill out or splash out, in other words, it will "fountain"
Fountain in OFFICES and PROS
The larger the cross-sectional area, the lower the height the ink will rise.
The smaller the cross-sectional area of the VO, the more air in the ink compartment, the more the donor is heated, or the more the air pressure in the room drops, the stronger the spitting will be.
In practice, every start of the heating season can lead to a fountain.
By the way, cooling too! Since heating is very likely after cooling, and cooled air contains large quantity molecules than hot, so the phenomenon during subsequent heating can be even more spectacular.
To combat fountains, it is recommended:
... do not allow the ink volume in the donor to decrease by more than 80..90% of the total volume. Those. air should be less than 10..20% of the volume of the PO.
...prevent heating and cooling of the donor
The exact amount depends on the volume of VO.
The "fountain" may not rise until it exits the donor, but even with some rise
The "fountain" is accompanied by rake No. 2, since a rise in the ink level in the VO violates the balancing conditions.
Marriott's rake No. 2 - "Stripes!"
In order for Marriotts to work, they must Right refill (see "Refilling donors").
Otherwise, you can get jars instead of Marriotts.
What will happen in this case, see "OFFICE Rake No. 1"
Users Very Often Fill Incorrectly without realizing it.
This is due to poor understanding by users of operating principles and poor donor designs (when the air compartment is hidden inside the ink)
"OFFICE" type donors
OFFICE type donors from different suppliers (all made in China) are more similar to each other than pancakes from the same frying pan. However, there are varieties.
OFFICES with a “partition” and “without a partition”. This means a way to organize the air compartment (VO) - separating a part from the Ink Compartment (ICO) by a partition. Another way is to form a VO, a short round compartment, as a separate independent part - an insert. Therefore, the top view is slightly different.
OFFICES with short round air compartment(without partition, KaKa-OFFICES, in straight um sense). 
,
Rake No. 1 refers to OFFICES with a short round VO (without a partition).
The design of the "OFFICE" donors (without a partition) is very interesting (IMHO - outstanding) and is designed, in principle, to eliminate the appearance of a fountain. It also makes balancing easier. However, due to the implementation, it turned out to be complete shit.
Here the stabilization is built on a slightly different principle, so the designers considered it permissible to reduce the volume of the air defense.
KaKa-OFFICES also know how to give a "fountain".
RAKE donors of the "OFFICE" type No. 1 - "It will strip!"
In addition to improper refueling, OFFICE donors have a second reason for the rake, their own.
Specifically, in more than half of the cases "OFFICES" NOT CAPABLE work in marriott mode.
The design features a short round air compartment (AIR) and two round reed valves. The first is on the lower edge of the air compartment, the second is from the inside under the upper surface of the donor between the air compartment and the wall closest to the VO. Externally similar donors "Office" not with a round compartment, but with a partition, are free from the described rake.
Therefore, the principle of operation of stabilization in OFFICES differs from the classic Marriott.
When the pressure in the CB decreases (the amount of ink decreases or the external pressure increases), everything is as usual. In this case, the upper valve closes and the lower one opens. An air bubble enters the BO through the open bottom valve and compensates for the pressure difference.
However, when the pressure in the emergency room increases (the air in the emergency room compartment has heated up, or the air pressure in the room has decreased), the operation is different.
In this case, the lower valve closes and does not allow ink into the VO, and the upper valve opens and releases excess pressure.
The idea is brilliant. When working correctly, the effective ink level (for an amount of ink of more than ~40 ml - the volume up to the lower cut of the BO) is always at the level of the lower valve, and the threat of “fountains” is completely removed. 
The top valve is hidden there, the petal of the valve, the top valve
In practice, both valves can cause trouble.
The lower one is prone to sticking, which prevents the passage of air from the VO to the PO.
The top one, on the contrary, does not always close. Mostly always open.
For guaranteed launch marriott you have to pierce the bottom valve and fill the top valve with sealant (removing the top trim).
In this case, one must be wary of heating the donors, as well as pressure surges. Otherwise, maybe fountain.

Why is this bad? More details - balancing, overflow
Jars and Marriotts are balanced differently. Jars - according to the upper level of ink in the donor. Mariotte - to the upper level of ink in the VO (i.e. along the lower edge of the air compartment - under normal conditions). OFFICES can work like mariots with an ink level of at least ~40mm - the lower cut of the VO (if there is less ink, the water seal disappears, the air in the ink compartment is directly connected to the atmosphere). Like jars - on the contrary, there should be less ink, the bottom cut should be BO. open.
When balancing OFFICES like Marriotts, the orientation is at the level of 40 mm. In this case, filling is possible to the top.
If a fully charged donor leaves the stabilization mode, the control level for balancing jumps to the top.
As a result, instead of a precisely dosed supply of ink, there is an “overflow”; much more ink is supplied than necessary.
Moreover. The ink flows by itself - by gravity!
Moreover. Ink flows even when the printer is turned off.
Where do they go? First they collect in drops on the nozzle plate. Then they are smeared on the plate.
During operation, the excess partially falls on the paper.
Excessively ink-saturated areas appear on prints.
When not in use, they partially drip into the mouth guard. Everything that is smeared on the plate begins to dry, forming a crust.
The crust prevents the nozzles from spitting and throws off the “sight”. The "bone blast" begins.
Now unprinted areas appear in addition to overprinted ones.
The phenomenon becomes noticeable to anyone when the steps jump out of their places in test prints.
Further development leads to clogging of the nozzles, which may temporarily occur during the printing process.
Then the nozzles fall out and come back.
For good.
The difficulty is that without experience you may not recognize the cause. "Flushing doesn't help!"- a common cry on the forum.
First you need to eliminate the root cause, then deal with the consequences.
Water-soluble ink is washable. The exception is debris that gets into the PG with ink.
It may not be washed out with debris.
OFFICES with partition free from the described rake No. 1 due to the lack of valves.
RAKE donors type "OFFICE" No. 2 - "Filters"
The kit for "OFFICE" type donors usually includes air filters in the shape of a top (spinning top).
At any temperature, the process of evaporation of liquid occurs. The ink also loses moisture.
In this case, the fumes pass through the air filters, and the filters become damp.
It is also possible for filters to get wet when donors tip over and during a “fountain” (see “Marriotts”). In the photo “OFFICE with filters” you can see two filters stained with paint from the inside (black and magenta)
One day, the filters will become wet enough to completely block air access to the VO.
As a result, the pressure will clog the ink channel tightly.
When you start cleaning, ink can still get into the PG, but this will only worsen the situation.
There will be no color when printed.
Next, the ink will dry out and simply removing the filter will no longer be enough.
Additionally, washing will be required.
Beautiful air filters can be kept as souvenirs, made into beads, or thrown away.
If you use filters for their intended purpose, be sure to remove and dry them often.
Ways to protect donors from dust
Good afternoon friends!
Have you heard anything about CISS? No? Or have you heard of it, but don’t know what it is? Now we will try to understand this issue!
What is CISS
Many of us have seen additional “accessories” for .
CISS is an abbreviation for the words “ continuous ink supply system».
It is used to reduce the cost of printing. This is a kind of “answer to Chamberlain” from users of inkjet printers addressed to manufacturing companies.
Not so long ago, almost complete idyll reigned in the field of inkjet printing.
Cartridges for inkjet printers had a relatively simple design that allowed without much difficulty refill them with ink or something similar to it. An entire ink production industry blossomed.
Moreover, companies that supplied so-called “original” inks to inkjet printer manufacturers did not stand aside either. Who would refuse additional income? The companies “Canon”, “Epson”, “Lexmark”, “HP” and others saw that the streams of money flowing from the sale of cartridges had become very shallow. And thought deeply...

The development engineers scratched their heads and responded with a multi-gun salvo.
That's all for today!
