By the way, about the Mariotte vessels... They are most effective only in the capsular CISS, because. cartridge is made on the basis of refillable cartridges, already equipped with balancing systems, and in which ink intake tubes are inserted instead of air supply.
Yeah, and the pressure stabilizes

02.08.2009, 15:09

Yeah, and the more I read your posts, the more I am convinced that you didn’t just come here ...
I wrote "most effective"!!! But he did not say that they are not needed at all in the cartridge !!!

03.08.2009, 02:07

Yeah, and the pressure stabilizes by magic.
The more I read this forum, the more I am surprised with the management of the Inksystem company, where are the pros ???, if not many clients will remain with you here and further. :)

I read and rejoice and I can’t understand, comrade, what are you stuffing into work?: ca:
With that kind of dedication you will go far :thumbup:

It was Sunday, there was nothing to do, and here is such an interesting forum where they give such "professional advice" why not help people drive off a little touch of professionalism and lower them from heaven to earth. ;)

For this system, it doesn’t matter what ink tanks you use, but only their position relative to the bottom of the printer (it’s correct to say the positions of the PG nozzle plate, but these are too complicated and not always necessary concepts for the user, hereinafter we will consider only the bottom edge printer - its bottom). For cartridge CISS, it is important to completely refill the cartridges themselves, i.e. so that there is a minimum of air in the cartridge. How to do it? Usually CISS cartridges are made of transparent polyethylene (PET), which allows you to control the amount of ink. Rotate the cartridge while pumping ink to draw as much air out of the inside of the cartridge as possible. It does not hurt to check the tightness of the system as a whole. Fold the ink plume in half and pinch the fold with a clothespin. Insert the 10 mm syringe into the cartridge, into the seat, and pull the syringe out of the cartridge. A small amount of ink will enter the syringe, but the cartridge should not empty completely, watch the inside of the cartridge, air should not leak in any connection, if bubbles still appear, find and fix the leak with high-quality silicone sealant. After pumping ink, you need to check the correctness of refilling. Take an ear stick (cut off the cotton) or an empty ballpoint pen, put the printer and donors on the same level on the table. Empirically determine the height of the position of the cartridges in the device (at what height relative to the table is the exit of the CISS cartridge), insert the tube into the cartridge, in the place where it is inserted on the PG needle, and squeeze the spring valve inside the cartridge. If ink flows down through the tube inserted into the cartridge, then in order to operate the device, you will have to raise the device itself to a height at which ink will not flow through the tube inserted into the cartridge. Well, if the ink does not flow out, and air enters the cartridge through the test tube, then the system is balanced correctly. The meaning of this procedure is that the ink should tend to return to the container, but the height difference should be minimal. In practice, this is usually achieved by placing the donors and the device at the same height. If in your CISS donors consist of two cavities in one body - the Mariotte vessel, then the container in which the larger container is completely filled with ink and the smaller one is completely empty is correctly refilled. If you have both cavities at the same level, then balancing is as follows: open both plugs, insert a fully expanded 10/20 ml syringe into the opening of the smaller cavity, push the plunger, the ink will leave the smaller cavity, close the plug of the larger cavity, pull out the syringe, everything - donors are balanced correctly. So, for such two-cavity donors, the height of the PG relative to the bottom of the device is not critical, because liquid from a larger container tries to rush into a smaller cavity, and, accordingly, cause the required vacuum in the cartridge. Insert the cartridges into the device and pump from the utility. Let the system rest for 1-5 hours. The downtime depends on the quality of the printout of the PG nozzle pattern, if all the nozzles are present on the printout, then you can start using the device, but if you have gaps in the pattern, then perform one more pumping and do not use the device for 3-8 hours. After turning on, pump and check the nozzles, if everything is in order with the printout, then we congratulate you on a successful installation :)

Theory is good, but practice is better.
Dear Afontia--how many years have you been printing? How many printers have survived?
We are trying to talk about high-quality photos that are not inferior to the minilab, and not about the narrow-minded printing of text and graphics.
I saw printouts of different printers in the representative office of INKSISTEM (I was interested in the pigment) bronze is present --- I did not find the point of switching from INTEKA to INKSISTEM (only the price of INKSISTEM 180g = 100g, INTEK 96g = 250g)
In terms of paper quality, this is another matter, compared with LOMOND, TETENAL, BARVA,
microporous is much inferior, and for a simple gloss, the price is steep (the pigment is erased).

You bought a CISS for your printer or MFP. In order for this device to work correctly and for a long time, it is recommended to remember the basic rules of how to use CISS:

• The ink tank must be flush with the printer. This condition must be observed. Because if you put the CISS above the printer or MFP, ink may leak into the printer body. If the CISS is below the printer, the ink simply will not flow into the cartridges and, as a result, into the print head of the printer.

• the large plugs of the CISS ink tank must be closed, and the small ones open. Instead of small plugs, air filters are inserted to prevent dust and debris from entering the ink compartments. Air filters must be clean and dry. If the filter becomes contaminated with ink, then it may stop passing air and the ink will stop getting into the CISS. In this case air filter it is necessary to replace or use a CISS without a problematic filter.

• the ink tank must be properly filled. The ink level should not be lower than the red line indicated on the flask to avoid air entering the CISS. If you are using a CISS with a non-cast flask, with an in-line arrangement of flasks, then you need to pay attention to the levels in the small and large compartments of the flask. The small compartment should contain the minimum amount of ink. Refueling is carried out through a large opening.

For clarity, below we give you the order of refueling CISS:

1. close the small compartment of the CISS with a small stopper (Figure 1)
2. fill the large compartment of the CISS flask to the upper level (Figure 2)
3. without removing the small plug, close the second (large) compartment of the CISS with a large plug (Figure 3). This provision is considered to be transportation and applies when transporting CISS with a printer.
4. open the small compartment of the Continuous Ink Supply System and insert an air filter instead of a small plug (Figure 4)
5. if the ink level in the small CISS compartment is higher than the permissible level (see Figure 2), we pump the CISS by injecting air with a syringe tightly inserted into the small CISS compartment without plugs. (Figure 5). Then we close the large compartment with a cork.

• When using water-soluble inks, print at least once a week to prevent the print head from drying out. If the printer is not going to be used for a long period of time, it is recommended to perform weekly preventive head cleaning using the printer driver. When using pigment ink on the printer, it is recommended to print more than 2 times a week.
• The ink cable of the Continuous Ink Supply System must be securely fastened and must not interfere with the movement of the print head during printing.

• Use only high quality ink. Fill with ink of the same type and manufacturer. This will prevent the failure of the print head, the cost of which is on average 80% of the cost of the printer. To change the type or manufacturer of ink, it is necessary to completely flush the CISS and printer print head, so ideally you should use the ink that was originally charged.

• almost all Epson printers resetting the ink level is done by pressing the chip button on the CISS cartridges. The zeroing procedure must be carried out carefully so as not to damage the cartridge chip. The cartridge is reset by pressing and holding the reset button for 3 seconds.

• it is necessary to use CISS at an air temperature of 15 - 35 degrees in a clean room, avoiding direct sunlight on the ink tank.

• when the CISS is idle for a long time or when it is being transported, it is recommended to close all the holes with rubber plugs, and also to break and clamp the ink cable to prevent ink from moving inside the system and getting into the printer.
• Keep ink away from eyes and food. In order not to get your hands dirty, it is recommended to carry out the CISS filling procedure with protective gloves.

If you have any questions that are not disclosed in this manual, you can contact the specialists of our ONLINE STORE ECONOMIC PRINTING for qualified advice.

CISS balancing. Everyone who uses CISS should know this.

Printhead inkjet printer can function properly only if certain conditions. One of these conditions is a slight rarefaction in the steam generator. When using cartridges, this vacuum is created by the cartridge itself, or rather, either foam rubber, the pores of which hold the ink in itself and do not allow it to flow independently through the PG nozzles, or the valve.
In CISS, donors are responsible for creating a vacuum, which, in this case, cannot be considered as a separate device.
The donor, as mentioned above, has a hole for air to replace the ink that has gone to print, and an outlet, which is considered to be the nozzles of the printer. In order to create the vacuum we need in the system, the ink level in the donor must be slightly below the nozzle level, i.e. donor exit points.
In the case of using ordinary bottles, without ink flow stabilizers, they must be installed so that the ink level in the bottle is constantly below the nozzle level (in fact, the level of paper exit from the printer) by about 1-2 cm. This will create the necessary vacuum in the system. It must be remembered that in the case of using simple bottles, this level must be maintained constantly.
Approximately the same situation with donors based on the Mariotte vessel. Only in this case there is no need to constantly monitor the level of ink in the donor.
Let's take a closer look here.
If in ordinary bottles the actual level in the tank is considered the ink level, then in donors based on the Mariotte vessel, the ink level is considered to be the lower edge of the air compartment, or air duct, and the actual ink level in the main compartment does not matter. Therefore, the balancing of the system should be done a little differently.
As with jars, two levels matter, the nozzle level, and the ink level, which should be slightly below the nozzle level. That's "a little".
The main error in balancing CISS with donors based on the Mariotte vessel is that users install donors on the same plane as the printer. This is not entirely correct.
Look at picture "A". The donor is installed on the same plane as the printer. The difference between the levels is significant, as a result we have too high a vacuum in the system.
In this case, after starting the printer (during startup, the printer turns on the pump and pumps ink into the PG), we can get a 100% nozzle test, but during printing, some of the nozzles disappear. After cleaning, everything is restored, during intensive printing, the nozzles "fall out" again.
This situation only indicates a high vacuum in the system.
To avoid such troubles, it is necessary to reduce the vacuum value by slightly raising the donor, and set the levels, as in the case of ordinary bottles: the ink level is 1-2 cm below the nozzle level, see fig. "AT"

It should be remembered that the value of 1-2 cm is not a standard, and in each case it can be different, a lot depends on the printer model, PG design, patency of the CISS channels, ink viscosity, etc....

The Law of the Russian Federation "On the Protection of Consumer Rights" in Article 8 obliges sellers to provide instructions for technical devices in Russian. Competent technical translation, unfortunately, is a rarity. And following instructions with inaccurate installation information can lead to unpredictable results. Sometimes, it is better to pay and use the service - installation of CISS, Novosibirsk is one of the many cities where this can be done efficiently and quickly.

A Brief Overview of Continuous Ink Supply Systems

For convenience, the review is summarized in a table.

In each case, there are pros and cons, the main thing is to decide what kind of end result is needed. Unfortunately, it is impossible to get a quality product for symbolic money.

CISS manufactured by InkTec are quite expensive and tests will have to be carried out for each new grade of paper. CISS from WWM, good quality and supplied with ink. But for some printers with minimal nozzle sizes, these inks are completely unsuitable and also not cheap. Therefore, it is difficult to do without consulting with specialists. With a successful installation, the user will only have to buy ink for CISS and, again, properly fill the system.

User instruction and transportation of CISS

Despite the assurances of CISS manufacturers and their installers that its operation is simple and uncomplicated, like any technical device, the system requires a competent attitude. Buying CISS is not even half the battle. A competent installation of the CISS, which does not harm the mechanisms of the printer and, accordingly, its correct operation, will not let you be disappointed in the efficiency of the system.

In the NPC system, the supply of ink to cartridges located in the case of a printer or other printing device is carried out from additional ink tanks via a flexible cable. The silicone tubes laid on the surface of the printer and inside it must be hermetically attached to the donor containers and cartridges. And, of course, they are laid without pinching or fractures at an acute angle.

Vessels of Mariotte

Its action is based on the ability of a fluid to flow from an area of ​​high pressure to an area of ​​low pressure. In CISS:

• in cartridges located in the printer case, the release of ink from the print head creates a rarefied area (low pressure) in them;
• the donor container is a vessel of two compartments, the smaller of which has an air column (high pressure).

Rice. 1. The principle of operation of Mariotte vessels

In practice, this leads to the fact that the vessels must be located approximately at the same level. If the donor containers are lowered, air from the cartridges enters the system below a certain level, which impairs printing. When the donor containers are raised above the level of the cartridges, ink flows out through the nozzles of the print head. Such an incident can be quite expensive for the owner of the printer.

The tight connection of the vessels prevents airing of the cartridge, which can lead to burnout of the SG nozzles. Ink, in addition to its main purpose, cools the print head from overheating.

Donor containers

These are vessels of significant volume, sometimes up to 200 ml, consisting of two parts or compartments. Most of it is filled with ink and closed with a plug. The smaller part is filled with air and a small amount of ink, the volume of which should close the slot into the ink compartment. This compartment is called the air intake and its valve is open in working order.

If there is too much fluid in the smaller chamber, the pressure builds up in the system and the ink will flow into the cartridge too quickly. To adjust the level of ink in the air intake, you can tilt the tank to the side larger camera and set the optimum pressure for operation.

The amount of ink in the CISS must be strictly controlled and topped up in time. Refueling:

• close the air intake;
• remove the cap from the larger chamber and add ink;
• close the ink compartment and open the air intake.

The most demanded volume of CISS containers is t50, i.e. 50 ml.

Transportation of the printer equipped with CISS

• Install the device and the system on the same plane prepared for transporting the device.
• Close the air intakes of additional tanks and pinch the cable.

Rice. 2. Transportation of CISS

Sometimes, pinching the system cable, the containers are placed on the printer cover, this is possible, but with a short movement.

The air intake of donor containers in working condition has an open air valve, and the ink compartment is closed with a plug. The air column regulates the pressure in the system and contributes to the batch flow of ink into the cartridge. For transport, pressure drop must be excluded. Without additional fluid pressure, the system will not pump ink.

Features of installing CISS for different printer models

Installing CISS on a Canon printer

After removing the cartridges from the printer, you must carefully remove the chips from them. The main thing is not to confuse. Insert the chips into the guides on the CISS ink tanks and secure.

Pour ink into donor containers, paying attention to their level in both compartments.

You can create pressure to fill the ink tanks with a syringe by squeezing ink out of the containers. Gently and gradually fill the cartridges with ink until a little liquid comes out.

Pinch the cable to stop the outflow of ink from the cartridges, put silicone seals on the print head fittings. Insert the cartridges into the printer.

The cable can be attached to the cover of the printer, if you immediately manage to adjust the length of the cable correctly, the cover will close well. You can fix it in a special mount that comes with the kit. The fastener is installed on the end part at the place where the cover is attached, but then it will not close completely. You will have to block the printer cover open sensor.

Installing CISS on an Epson printer

After unpacking the device and checking the contents:

• fill donor containers with ink;
• to pump ink into the CISS cartridges, pierce the film with a syringe needle, the cartridge valve is blocked in the open state;
• squeeze the ink for the CISS into the ink bottle through the donor air intake with a syringe until the paint comes out in its hole;
• the mount from the CISS kit can be bent at a right angle, it is possible with the help of heating;
• turn on the printer, wait for the carriage to move and disconnect the power cable;
• move the carriage manually to the left until it stops and lift the ink unit up;
• move the carriage to the right and install the ink tanks in the intended place;
• glue the bracket and fix the cable;
• check the carriage travel and additionally attach the cable to the outside of the printer.

Be sure to repressurize the system before starting printing.

Subsequence:

• fill donor tanks with ink according to the marked colors;
• after closing the filling holes, open the air intake and carry out pumping;
• prepare the cartridges by removing the stickers and expanding the air hole with a drill;
• strengthen the spacers and the seal in the hole, other holes of the cartridge must be closed with plugs;
• the cartridges are pumped, the protruding ink is carefully removed with a napkin;
• release the print head and check the order of the colors, for this it is enough to run it over a sheet of paper;
• turn on the printer, turn off the power when it is placed in the cartridge replacement position;
• place the cartridges in their mounting places and fix them with fasteners;
• fix the cable without interfering with the movement of the carriage.

With proper skill, any work is performed at a satisfactory level. And if you add considerable experience and professional knowledge, it will be performed at the highest level.

The first acquaintance with the continuous ink supply system (CISS) causes deep respect for hydraulics and other pundits, a glorious cohort of engineers. For me at first, CISS caused a feeling of something extremely complex. The ornate weave of pipes in the company of bizarre vessels, and even secret handkerchiefs with electronics, look like toys of an inventor or a wizard who mysteriously makes the printer meekly eat without claims to the owner, completely forgetting about his eternal begging to buy him new cartridges.

So that's what the engineers came up with - to force inkjet printers to be powered from large jars of ink and at the same time produce print quality no worse than when printing with native cartridges from their manufacturer.

When we begin to look more closely at the CISS, everything begins to clear up and you involuntarily think: “It's simple, how could I not have thought of this before!”. Therefore, putting aside false fears, let's look at the CISS from the inside and figure out how it works.

Rice. 1. Scheme of structural elements of CISS

The main parts of the CISS are containers with a supply of ink (donors), a pipeline transporting ink to the printing unit (loop), containers transmitting ink to the print head (PG) and, depending on the printer, a set of autochips.

The donor vessel 1 contains a supply of ink 3 (see Fig. 1) for the printer. It is a Mariotte vessel, but we will not delve deeply into the works of great physicists, and we will only say that it provides ink supply through tube 4 with a constant pressure, independent of the amount of ink residue in the donor. Thanks to the air duct 2, such a wonderful jar, no matter how much is filled into it, produces a slow uniform outflow of ink, in other words, a constant stable low pressure at the outlet. This is extremely important for the operation of the printer and its power supply.

Donors are connected to the printer's printing unit flexible cable, through which ink is transferred to your insatiable assistant. The train always looks colorful, it can be glued together from 4, 5, even 6 and 8 tubes, in which ink of different colors overflows. If you look at a working printer with an open lid, it becomes clear that this hard worker got a savory share. He constantly wriggles, obediently following the printer carriage, all the while cyclically folding and straightening.

From the loop 5 (see Fig. 1), the ink enters through the receiving pipe 6 into the tank 7, installed directly above the print head 8. It is from the tank 7 that the PG of the printer is powered.

On the fields of the Internet, irreconcilable battles still flare up from time to time over these tanks, which directly feed the SGs. They can be cartridges, capsules or dampers, after which the CISS model is called, respectively - cartridge or capsule, for example. I will not compete with supporters of certain systems, so as not to be accused of adherence to any camp of fans, but to remain simply a supporter of the use of CISS.

Autochips provide information to the printer processor that everything is normal with power and it can continue printing. To be more precise, information is transmitted about the correspondence of the cartridge to the original one, that the level of ink in the cartridge is sufficient, the original ink is supposedly used, and the cartridge is new. This is how these caring nannies lull the printers into being attentive and wary of their consumables.

Such, in a quick review, is the design of the CISS, essentially a correctly coordinated system of communicating vessels, but made with high quality and without flaws, which is what we owe to a cohort of enthusiasts who have gone through a thorny path of mistakes and achievements.

The importance cannot be overlooked correct installation donors by users when operating an inkjet printer equipped with CISS. Often, when a group of donors is located in the wrong position, calls to our service follow with calls for help or disappointed messages that the printer does not print or even insidiously spilled ink on the table. To avoid this, you must carefully study the instruction manual, and most importantly, do not place donors on books, coasters or other shelves, or even put them on their side.

Main rule , - donor containers should stand vertically on the same surface with the printer, not lower and not higher, I draw your attention - on the same table, next to the printer. And of course, do not wait for the end of the ink, do not allow the system to air. And experiments on mixing colors will lead to the fact that your printer will turn from color to disabled, printing only in gray.

Fig 2. Scheme of the CISS level balance

Animated figure 2 shows the options for the location of the donor in relation to the level of the print head (PH). To be frank, it is not even the level of the location of the donor tank or its outlet tube that matters, but the level of the tip of the air duct 2 (see Fig. 1).

It is its relative position with the level of the PG 8 nozzle platform (see Fig. 1) that determines the normal operation of the printer. In the ideal case, this is the location of the tip of the air duct and the platform of the nozzles at the same level (pos. 1, fig. 2). In this case, the pressure in the SG is zero. However, this is difficult to achieve in real operation, due to fluctuations in temperature and atmospheric pressure. However, this is a topic for a separate, fundamental article.

If the air duct is located deeper, below the level of the platform of the SG nozzles, then up to a certain limit, the surface tension forces in the SG nozzles still retain ink (pos. 2, Fig. 2). This is how many CISS work. But more than this redistribution, the negative pressure that has arisen as a result of the height difference overcomes the forces of surface tension and the steam generator is aired (item 3 of Fig. 2). The printer starts to streak and then it can start printing to no avail, while the rest of the ink tends to flow into the donor.

When the tip of the air duct is located above the site of the PG nozzles, the surface tension forces can hold the ink in the PG up to a certain limit (item 4, Fig. 2). But when it is exceeded, further raising the level of air intake (the tip of the air duct), the excess pressure caused by the difference in levels causes the ink to break through the barrier (pos. 5 of Fig. 2), and spill into the printer with a cheerful mood and further onto its stand.

This is the actual situation in the relative position of the donors and the printer. I hope this article sheds truth, not ink, to novice CISS users.

The CISS will repay you with a long and reliable work with an attentive and competent attitude towards it.
