Uninterruptible ink supply system. Continuous Ink Supply System

2 years ago

Anyone who has a printer will sooner or later have to face the concept of CISS. And what does this abbreviation mean? CISS is a Continuous Ink Supply System.

Systems continuous feed inks have been used in inkjet printers. The name itself suggests that the ink supply to the printer's print head is provided continuously as they are consumed. Such a device supplies ink from separate reservoirs. The amount of ink in native cartridges is limited. And in the CISS, external ink containers are used. They have a lot more volume.

Such a device provides an opportunity to increase the number of printed documents and images. But not only. It is allowed to use alternative paints, which are sold in special packaging. We emphasize at the same time that their cost is much less compared to the original ones.

There are no problems with the acquisition of a continuous ink supply system. They can be bought at any outlet that sells printing equipment.

Why is CISS needed?

The use of CISS leads to a reduction in printing costs. At the same time, the cost of one print becomes ten times lower. So, savings on the face.

To put it simply, CISS are donor containers. To connect them, a thin cable with cartridges is used, which do not have a filler inside, that is, “foam rubber”. And this is different from the original cartridges.

The supply system is sealed. The resulting vacuum compensates for the flow of ink from the reservoirs into the cartridges. As a result, ink can be constantly and continuously supplied to the print head.

Continuous ink supply systems come in cartridges, capsules, and dampers. The most popular CISS on cartridges. They are reliable. Installing them is not difficult. It's easy to operate them.

Buying capsule and damper CISS is cheaper than cartridge ones. They should only be installed by a specially trained technician.

Benefits of using CISS

The continuous supply of ink on an inkjet printer has its advantages, which we will discuss.

Systems can be quickly installed. It takes 15-20 minutes for a specialist to install the device. And so that you do not need to make any changes to the design of the printer.

There are significant savings. CISS gives savings on printing from 20 to 60 percent compared to using original cartridges. Reducing the cost of printing - 20 times or more.

At the printer high performance. In a printer with CISS, there is no need to change cartridges, clean the print head when drying occurs. You can print large volumes of photos and documents without any risk that the ink will run out and the device will stop.

Printing is safe because with a continuous ink supply system, there is no risk of air getting in and resulting in print head breakage, which is acceptable when you produce regular replacement cartridges.

Ink can be replenished as it is used up. Let's say, when a certain color runs out in the containers, it is only necessary to replenish it. In such a situation, in conventional cartridges, it is necessary to change the entire cartridge. Note that an old, used cartridge use of CISS no need to throw away. You just need to refill the ink tanks.

Since there is protection against air ingress, the life of the printer is extended. CISS have self-resetting chips that are able to restore the ink level automatically.

The company's warranties are usually retained because there are no mechanical damage devices. It is allowed to use inks of other manufacturers and other types that are not supplied in cartridges.

Cons of using CISS

Now a little about the disadvantages of using CISS. Indeed, when installing them, there are some problems and even dangers. By by and large, minuses are, rather, features of operation. And you need to pay attention to them, and not to real shortcomings.

Some printer manufacturers, for example, refuse to warranty service printer when the CISS was installed on it. However, thanks to the CISS, you can very quickly recoup both the printer itself and original cartridges on him. And therefore, this shortcoming must be treated as a convention.

The system must be installed without air access. At home, this can be problematic. Contact the experts. Moving the printer with CISS requires great care. Otherwise, the ink supply to the print head may be damaged.

But in general, CISS is no worse than printer cartridges. With proper and careful installation, you can count on a significant increase in the life of the printing device. During the installation of the CISS, you only need to carefully lay the cable. So that it does not interfere with the movement of the print strip. And choose only good colors.

A printer today can be bought at a price of one and a half to two thousand rubles. It's a paradox, but the cheaper the printer is, the more expensive its maintenance will be, and the cartridges in its kit, as a rule, are refilled only by 30-50% of the nominal volume. It is worth noting that such wasteful maintenance only applies to inkjet printers, while their digital analogues always more expensive and more economical. Yes, and you can refill the printer cartridge an unlimited number of times, only color and photo printing can please its owner very rarely. However, craftsmen have learned how to refill "disposable" cartridges for inkjet printing, but no one bears guarantees of their safety during refueling. More recently, a useful invention has appeared in the world of office equipment called CISS, the abbreviation of which means continuous ink supply system, which allows you to save hundreds of percent by avoiding the purchase of expensive inkjet cartridges.

The principle of operation of the CISS for the printer

Ink when using the CISS for the printer is supplied in a continuous stream from refillable reservoirs directly to the print head. The CISS for the printer consists of several Marriott vessels, silicone cables and the ink itself, which, due to the complete tightness of such a system, is supplied under pressure to the print head. As a rule, you can install the CISS for the printer yourself, especially since there are many video tutorials on the Internet that demonstrate the method of installing the CISS. The ink supply system is not know-how and is widely used in large-format and interior printers, with the only exception that the built-in CISS is hidden from the user's eyes. In simple terms, CISS is a set of four vessels with paint and plumes like those used in droppers. Any CISS kit comes with a drill for expanding the holes for the cable, syringes for filling Marriott vessels, hygiene gloves and washing liquid for the vessels. A clamp is used to pull the cables when installing the CISS.

When installing CISS on your own, you need to read the instructions and soberly assess your strengths. In case if self-installation CISS is impossible, you should call the pros, otherwise you can ruin the cartridge.

Benefits of Using CISS for Printer

When printing with branded cartridges, they are replaced even if the cartridge runs out of only one color. In the CISS, you can visually assess the consumption of ink and add them as needed. CISS is simply necessary for the commercial use of the printer, because the cost of printed photographs and booklets will be reduced to 20-50 kopecks per piece.

A printer with a CISS should be installed in one place and not subjected to frequent moves, because one awkward movement can provoke depressurization of the entire system.

The real savings when using CISS reaches hundreds of percent. When printing a large volume of products, you can not be afraid that the printer will stop printing due to a lack of ink in the cartridges. We should not forget about the environmental component when using CISS, because such a system is durable, and the user does not have to litter the environment with used cartridges, which are rarely recycled in Russia.

Many happy printer owners have already installed a continuous ink supply system. The advantages of such an improvement in the printer are obvious: you don’t need to buy expensive cartridges, you can always see how much ink is left in the tank, when the ink level decreases, it’s enough to add the right amount, the price of one printed copy decreases significantly and finally you can make such a system yourself. The author of the homemade product was also tired of constantly changing cartridges and he decided to make the CISS on his own.
Tools and materials:
-Scissors;
-Duct tape;
- Instant glue;
-Medical gloves;
-Screwdriver;
- Syringes;
-Cartridge;
-Printer ink;
- Thin transparent tube;

The author purchased the handset at a radio store, paint at the store. Moreover, the paint is needed precisely in jars, if the paint in syringes needs to be poured into a suitable container.
Step 1: Preparing the cartridge
First, the author washed the tubes with detergent and dried them. Then he took water into the syringe, inserted the needle into the hole in the upper part of the cartridge (under the sticker) and rinsed each chamber. Took off neatly top cover cartridge. Cleaned the inside of the cartridge. All dried well.

Step 2: Cartridge Assembly
Puts the sponge back in place. Tubes are installed in the opening of the cartridge cover. Each color has its own tube. If necessary, the holes must be enlarged, but the tubes must be inserted tightly. Then glue seals the joints. Attaches the top cap to the cartridge. It is necessary to glue so that the cartridge compartments are also isolated from each other. There should not be a single unsealed area both around the perimeter and between the cartridge compartments.

Step 3: Installing the CISS on the printer
Having opened the cover of the printer, it installs the cartridge in place, and brings the tubes out. The cartridge is fixed in the carriage with a clamp and tape.

Step 4: Filling the CISS with ink
There are usually two holes on the cartridge cover for each color. The author inserted a tube into one, the second should remain open until the end of refueling. Then the do-it-yourselfer draws ink into the syringe and slowly fills the cartridge compartment with ink through the tube. It is important not to mix up the colors and refill the ink of the color that was originally there in each compartment. After filling the compartment and the tube, the author closed the opening of the tube with chewing gum. Thus, it fills all the compartments of the cartridge. After filling, seals the remaining holes in the cartridge cover. Makes two holes in each ink jar lid. One in the center of the tube cover. The author made the second as follows: he made a hole on the side of the cap with a syringe needle, inserted the needle into the hole, and into upper part needle inserted a piece of foam rubber. It turned out an air duct with a filter. After removing the chewing gum from the tubes, he inserts them into the holes in the lids by color. The tubes are lowered to the bottom of the container, but not all the way.

Step 5: Zeroing and Ink Pass
Most printers software prevents the cartridge from being reused. In order for the printer not to "swear" it is necessary to reset the cartridge chip. For his printer, the author downloaded special utility. I installed it, chose the counter reset function (with the printer turned on) and confirmed the action. Turned the printer off and on again. After the zeroing operation, it is necessary to drive the ink by turning on the nozzle cleaning mode.

A little from myself.
1. For washing, it is advisable to use not water, but a special washing liquid sold in the same place as printer ink.
2. When installing the cartridge in the carriage, it is necessary to route the tubes correctly. The carriage moves and it is necessary that the tubes do not cling anywhere.
3. It may be necessary to make holes for the tubes in the body or cover of the printer.
4. It is better not to disassemble the cartridge (which the author mentioned at the end).
5. The utility that the author installed works with old operating systems, so I don’t provide a link to it. The network is full of instructions on how to zero exactly your cartridges.
6. This instruction more suitable for printers with 2 cartridges (one black, one color). for such printers, CISS is practically not found on sale. For printers where there are several cartridges by color, it is better to purchase ready-made CISS (although you can do it).
7. It is better to use branded ink.
8. The ink level in the tank should not drop more than half.

I don’t know about you, but my close acquaintance with the photo printer began with disappointment. No, my Epson 890 fully provided the declared quality, it printed well on roll paper, the color reproduction was often better than when printing in a photo lab ... But I was taken aback by the fact that when I looked at the ink consumption monitor after printing several A4 sheets, I was stunned - ink more than half used up. Then I reassured myself that I would print at home only some urgent work, for which it would not be a pity to spend more money for the sake of necessity. But, of course, the joy of buying significantly decreased.

The second disappointment lay in wait for me when, about a month later, the red light on the printer turned on when it was turned on again, demanding to change the cartridge! This is despite the fact that since then (i.e. since the first shock) I have not printed anything on it at all! This is how I learned that each time the printer is turned on, it cleans the head and consumes some ink. And if the printer is not turned on, then the head will dry out, and washing it will also cost a pretty penny.

Yes, manufacturers of photo printers in every possible way support in us the illusion that you can just buy an inkjet printer, and then print well and a lot at home. Yes, you can do well and a lot. It's just that it's very expensive. Of course, manufacturers of photo printers are interested in selling as much of their equipment as possible, and then as much as possible. Supplies to it (as a result, the printers themselves can even be sold at cost - with a more or less significant load, the cost of consumables will quickly pay for any discounts). Therefore, buyers - that is, you and I - are still caught by various advertising tricks of printer manufacturers. For example, in the characteristics of "ink consumption", where you can read that the cartridge is enough for 200 pages, the parameters are indicated not for photo printing, but for printing with the so-called 5% coverage. Really - this is text printed with two intervals. How often do you print colorful text?

So the number of users who are not at all satisfied with the product for which they paid their hard-earned money is growing. User attempts to cut costs (such as refilling their own cartridges) are blocked by Epson with what is known as a smart cartridge. That is, each Epson replaceable ink tank, in any printer produced over the past 3-4 years, is equipped with a memory chip. This chip remembers the amount of ink used, and the consumption is not determined exactly, but approximately - according to the reports of the printer driver. As a result, the chip reports that the ink has run out, as a rule, in advance - approximately when 20-30% of the ink is left in the cartridge. Such a cartridge cannot be refilled, since the said microcircuit will give the printer information not about the amount of ink that is actually in the cartridge, but about the amount that was there before refilling.

Epson cartridges equipped with smart chips.

Users, however, still looked for various ways to reduce the cost of printing. As a result, two fundamentally different solutions were found.

1. Refilling of cartridges, and for Epson - with the obligatory zeroing of the smart chip.
2. The solution that will be discussed in this article is the creation of a continuous ink supply system (hereinafter CISS).

The idea of ​​attaching a barrel of ink to a print head has been in the air for a long time. There were many problems on the way to its solution, and their enumeration is good topic for a separate article.

I note right away that it makes sense to do CISS for printers in which the print head is not combined with the cartridge - it has a longer resource than a replaceable one, so the print quality will not fall over time. Epson and Canon printers meet this requirement. I will talk about CISS for Epson, they are structurally more complex and more common with us.

The CISS that are now common have some absolutely similar elements, but at the same time their designs differ in some ways. Mandatory elements CISS designs for Epson printers:

CISS photo on Epson 890 printer. CISS elements

The first is a smart chip deception system

Can be implemented programmatically, using various service utilities that can reset the value Epson cartridges, or "freeze" the ink level in them, so that it is not consumed. When I started dealing with refilling cartridges, I tried many of these service utilities. In principle, they work, but not always. Some of them support only a parallel interface, and do not want to function over USB. Yes and after Windows installation XP on my computer, I could not find a working utility for freezing or resetting smart chips for my printer.

Another system can be implemented on the so-called "self-resetting autochips". What it is? Chips have been developed that mimic the behavior of "native" from Epson. They show that the ink level is decreasing, but as soon as it reaches a minimum, the chip is reset to its original state. The operation of the autochip, unlike the operation of the service program, does not depend on operating system computer and printer interface. Therefore, for me, autochips turned out to be the preferred solution, despite the fact that they are the most expensive element of the CISS.

Auto-zeroing chips

Is it possible to just make a chip that will show a constant level of ink? It turns out that it is impossible, because the printer will consider it to be faulty and refuse to work after the first printed document.

The second element which is needed in the CISS, this is a train of thin tubes, through which ink will be supplied to the print head.

Silicone cable

The cable is needed because we cannot place our "ink barrel" directly on the print head - firstly, because physical dimensions, and secondly, because placing excess mass on the printer head is unacceptable. Our cable must be flexible, resistant to wear, have a sufficient diameter of the tubes for supplying ink, but not excessive, so as not to create an additional inertial load on the moving head.

Third element, which is located between the loop and print head, This damper capsules or cartridges. The bottom line is that the ink tubes from the reservoirs cannot go directly to the print head. Firstly, it is designed in such a way that some pressure of a liquid column, in our case, ink, is necessary for operation.

Various ink dampers: cartridges, interlocked pods, syringe pods, single pods

Secondly, ink, like any liquid, is prone to evaporation. Small air bubbles may appear in the tubes of the plume, especially in the heat. If you have a damper chamber, these bubbles accumulate in its upper part and do not affect the ink supply to the head. If there is no such damper chamber, then the bubble is sucked into the head, and the corresponding color is no longer printed.

Thirdly, with a large consumption of ink of the same color, they simply may not have time to approach the print head along the thin tubes of the cable. The result is the same - unprinted image elements.

A good damper chamber is a "native" cartridge from the manufacturer. It is calculated and calculated and has a relatively large volume, so gas bubbles are easily damped by it, and it also creates sufficient pressure in the liquid column. There is only one drawback: the cartridges have big sizes, they fit tightly into the print head. In some printer models, pressure caps interfere with laying the cable if we use a cartridge.

Alternative - specially made capsules smaller. They can be combined into a block, or they can be placed in the print head separately. Capsule systems are more technologically advanced. We can always remove or change one of the capsules. If you need to wash the head, you can attach a capsule with washing liquid to the inlet nozzle of the head and wash the head in one specific color. Accordingly, it is much easier to lay a loop from the tanks to the damping chambers.

Capsules made from syringes do not have membranes and support required pressure due to the liquid column of ink 2.5-3 cm high, as in the native cartridge. At the same time, syringe capsules are less fragile than special ones, the membrane of which can be damaged.

Bar for the capsule system of the LP printer P300

Autochips with a capsule ink supply system are mounted on a special bar, or on a block of capsules. If cartridges are used, then directly to the place of native chips.

Next, the fourth element of the CISS is large containers with ink, where the ink is supplied to the head. There are few requirements for them. It is important that dust does not get into them, and that they have sufficient volume, plus ease of handling. Therefore, the same vials are often used in which the ink is supplied.

Last, the fifth element of the CISS - supporting elements for the loop from tubules. They are needed so that the train does not wear out during movement and does not jam with the head. For systems with vertical arrangement cable, like the R300, its use is not required.

The practical construction of CISS for me personally began with an acquaintance with the site where I wandered in search of ink for refilling. The site is built as an online store and is dedicated to different ways cheaper printing on color inkjet printers. In addition to ink for refilling, there are offered both various accessories for CISS and complete systems.

A distinctive feature of the site is a live full-fledged forum. Actually, it was after talking there that I made a decision for myself to buy CISS and made an order. The cash on delivery order came to me by mail after 13 days, and cost 15% more than the price indicated on the website due to postage for shipping the goods and transferring money.

The CISS for the 890, which I ordered, consisted of two cartridges with autochips installed on them and a loop of elastic tubes glued into them. The black cartridge has one tube, the color cartridge has five. The cartridges are already filled with ink - no need to mess around. No need to fill the tubes of the loop with ink. The air that is in them will then accumulate in the upper part of the cartridge and will not affect the print.

In principle, it was possible to follow the instructions: remove the clamping covers, insert the cartridges and secure them with the included clamp - the same as thick wire harnesses are pulled. Now this decision seems to me more correct, but then I spent 20 minutes melting a place for laying the cable with a soldering iron in the clamping covers. I decided not to hide the last one inside the printer, but lay it outside. I made holes in the ink vials with a thin soldering iron, inserted the ends of the tubes from the cable tightly there - so that they reached the bottom.

Air filter from a needle for a syringe. The cotton ball should not be dense

So that air enters the bottles, and dust does not get there, you can not only pierce holes in the corks, but insert the needles from the syringes with the tubes up and plug the tubes with loose cotton tubes to serve as filters.

In total, the first installation of CISS took me 40 minutes.

The system that came for the 950 printer was cartridge-based in design. It is also fairly easy to install.

HPC cartridge system for Epson 950 printer.

The first step is to remove the top cover from the print head. In general, this cover does not carry any function initially, it only covers the cartridges from above. Cartridges at the 950th printer are held on by two latches - on each cartridge they are located in front and behind. Therefore, the cover can be removed without hesitation. The lid flips back and wobbles back and forth. At the same time, it is gently squeezed out with a screwdriver at the attachment points. When the grooves in the mount and the pins on the lid hinge match up, the lid will pop out of the hinge. If you act carelessly, the studs will break off, but then you can still put the cover back on and it will function as before. The cable in the 950th model is easiest to lay behind the head parking area and lead out of the case through the ventilation slots at the back.

The system for the R300 was a capsule system. Its installation is different from the installation of the cartridge system.

First, we remove the top cover of the printer (this is described in detail in the instructions) and install a bar on which all six autochips are fixed.

The chip bar for the R300 system is inserted into the printhead

Then we put the capsules on the receiving nozzles of the print head. We lay the cable inside the printer, along the electrical cable (this is described in detail in the instructions), we bring it out of the case through ventilation holes and dip into ink bottles - as described above.

The cable is best brought out from behind through the ventilation slots.

After that, the installation procedure begins to differ. We take a syringe and a clerical clip (they are also included in the delivery). We remove each capsule from the nozzle, put it on a syringe, and suck off the air until the ink from the bottle fills the capsule about half through the tube of the loop.

Capsule filling

With a clerical clamp, we pinch the tube anywhere, after which we disconnect the syringe, and put the capsule on the receiving pipe of the print head. Remove the clerical clip from the tube. Repeat with each capsule.

I did not have special problems with installation of any types of systems. However, there were a couple of points worth mentioning.

After installing the system, one of the cartridges may show zero value. For me, this problem disappeared after I wiped the contacts of the head and chip with an “architect” eraser, and then with alcohol.

In the 950th system, the cable for some reason strove to “get hushed up”. I fixed the plastic support pad holding it slightly skewed, so that it directed the plume slightly upwards. That helped.

The site's forum also discusses problems that may arise when installing CISS. In any case, I advise you to look there, but I will tell you about several issues described there.

One of them is a violation of the tightness of the system. Actually, the system works due to the fact that the ink that is consumed by the head is sucked into the damper chambers from bottles. If the tightness is broken, then not ink is sucked in, but air, and the corresponding color disappears. The tightness is most often broken either at the junction of the cartridge and the receiving pipe of the print head (treated by replacing the seal), or at the place where the cable is pasted into the cartridge or capsule (treated with a drop of glue). Cases when the train was worn or torn, I did not meet on the forum.

The forum also describes cases when people put CISS with water-soluble ink on printers with pigment ink. Sometimes this is acceptable, sometimes not. However, in any case, it is first necessary to rinse the print head well with a special flushing liquid to remove pigment ink residues.

The economic effect of installing CISS is very, very large. Studies have shown that filling an A4 sheet with one color consumes approximately 0.8 ml of ink. According to the most modest estimates, 200 ml of ink from a bottle in terms of 15 ml of cartridge capacity is 13 cartridges (i.e. 13 sets, respectively). However, if we remember that the cartridge in printers with separate colors by cartridges is underused by 20-30%, and the cartridge with combined colors by up to 50%, then the number 13 can be safely increased to 20-25 (respectively, 20-25 sets of cartridges ).

In general, it turns out that a set of CISS plus ink, costing about $ 150, provides an amount of printing equivalent to about 20-25 kits cartridges. If you buy native cartridges, then for the same $150 you can buy only 1 set for new printers, or 2-3 sets for old models. In the future, the cost of owning a CISS is further reduced by half, since a set of 6 inks can be bought for $67, and this is the cost of 2-3 native cartridges. That is, you will purchase 20-25 sets of cartridges for the price of one set or even half a set :)

The good thing about using CISS is that you have the same ink for a long period of time. Consequently, the predictability of printing results is increased, it is possible to choose for these inks color profile- the one that you need, under the right paper. If you order a printer calibration service (in Moscow it costs about $40), then it makes sense to give your hard-earned money only if you will use the results for a long time. You can, of course, buy a calibrator and build profiles yourself every time, since calibrators now cost not such big money as they used to. But, in my opinion, it's easier to use one type of ink and several types of paper anyway, than to re-calibrate each time a paper-ink pair.

From myself I can add that I usually print on Lomond paper. The profiles downloaded from the site for Epson printers and Epson inks are also perfect for the WWM ink that comes with the CISS.

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 a lot of money. In contrast, CISS consists of large ink tanks (usually 100 ml of ink of each color), which are economical in consumption and can be refilled multiple times.

CISS installation: instructions and useful tips
Owners inkjet printers Those who have to print a lot at home or at work have probably heard a lot about CISS. True, not everyone fully understands what it is and how it works, therefore in this article we will try not only to talk about the new device in an accessible way, but also to explain how to install it.
The basic rules of operation can be seen here in this video

Types of LFC systems and their characteristics
Deciding to buy a continuous ink supply system and looking for suitable options, you will see that it comes in two forms:

1. Standalone - this is a stand-alone device that is suitable for most models of MFPs and printers famous brands. It can be purchased separately and installed by yourself or contact the experts.
2. Embedded - a system that is sold complete with printing devices that are designed for full-color printing for commercial purposes. The world's leader in built-in CISS this moment is Epson with the "Print Factory" line. In addition to all the advantages of the "factory" CISS - there is one very important drawback - the price. The cost of printers and MFPs with this system can exceed 2 or 3 times compared to similar models with a stand-alone CISS.

Noting the advantages of CISS, it is worth saying that it is not connected, like cartridges, with the print head of printers, therefore there is always access to it and refill ink desired color it is possible when the need arises - even during printing, which will guarantee its uninterrupted operation. It is also important to note that this modern system is ergonomic, which means that it does not take up much space and is convenient to place - some models are a unit that can even be installed remotely from the printer so that it does not take up space on the desktop. However, it is important with this installation that the system is on the same level with the MFP, otherwise the ink may simply leak into the printer and cover up your favorite table / carpet / sofa.
Verified manufacturers
Having bought a cheap CISS made in China, you may find 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 sure of the quality of the product and that it comes with instructions that make it easier to assemble and install. Of course, you can try to install it yourself by downloading the manual from the Internet. Only in this case, there is a fear that during the connection the air exchange system of the bypass valve will be broken, and the CISS will not be able to work.

Ideal if you order printing device, complete with there is a system NFC, for example, such MFPs as - Epson XP-330 or Epson XP-342, then you do not risk anything and will be sure of its normal functioning. The second option is to buy the printer from one company and the system elsewhere. So you save 3-5% of the total cost, but you completely lose the guarantee for the printer, since no one wants to service third-party CISS. So this option we do not advise you and recommend buying everything in the complex.
Self installation
If you are used to doing everything yourself and took up the installation of the CISS with your own hands, then just take the instructions and follow everything that is written there:

1. Use tubes to connect containers to cartridges.
2. Fill the cartridges with ink.
3. Open the bypass valve to remove air from the tanks.

The main thing to remember is to control the level of ink and in no case allow air to enter the print head. If this happens, contact service center can't be avoided.
Issues you may encounter
When buying 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 the continuous ink supply system must be raised high. In addition, CISS may not fit your printer model at all, so carefully study the list of devices with which it is compatible. Do not forget that there should be instructions included with the device, this will guarantee that you have bought a quality product.
CISS is, of course, very profitable and will reduce your printing costs, so you should not doubt the expediency of acquiring it, just approach this issue responsibly.
