How to remove air in the continuous ink supply system. Bleeding CISS printers Canon and Epson
Many users of inkjet multifunctional devices with CISS regularly encounter the problem of air formation in the nozzles of the system loop (especially owners of Canon and Epson office equipment). This applies to both office equipment with a standard continuous ink supply system and a plug-in one. Usually this happens due to prolonged downtime of equipment, untimely refueling of CISS containers, or improper use of a printing apparatus with an NPC system.
In this article, we will tell you how to get rid of air in the tubular loop of the NPC system, give several ways to pump the CISS all-in-one printer Canon and Epson, and also note about the basic rules of using office equipment with a constant ink supply system.
Rules for the operation of printers with plug-in and standard CISS
To save you from unnecessary spending of finances and time, we recommend that you familiarize yourself with the following features of using office equipment with a constant ink supply system:
Containers (containers or donors) CISS and printer Must be on the same plane.
If you put the all-in-one printer on the table, then the ink system should be next to it. Determination of CISS above the level of the device will entail overfilling of the printheads with ink, followed by its flow into the printer. In turn, if the CISS puts the all-in-one printer below, then the ink will stop reaching the cartridges. As a result, gaps will appear on the prints, as well as voids will begin to form in the ink plume of the NPC system. Most often, these problems appear after cleaning, during which many people like to put CISS donors on a printing device and forget about it.
Attention: If you notice voids in the plume, rather than lifting the CISS up to drive the ink through the plume tubes. This will lead to very negative consequences. Pump the CISS correctly, exactly with the established instructions.
Donors CISS Must be replenished with ink in a timely manner.
In no case, do not allow the complete emptying of the CISS containers. The continuous supply containers must always contain colorant. Also, make sure the ink level is always NOT below 1.5 cm from the bottom of the donors. Timely refueling will avoid the formation of air jams in the channels of the CISS loop tubes. Only refueling should be carried out without fanaticism, so that the ink does NOT flow through the air or refueling holes. Leave about 1 cm to the top of CISS donors.
CISS containers Must always be clean.
Continuous feeding system covered with dust, ink drip or other dirt, will not work properly. In addition, when particles enter the colorant, they can reach the printheads. This will negatively affect not only the quality of printing, but it can also damage the PG, cartridge or printer. DO NOT be lazy to periodically clean the CISS containers, especially before replenishing them with paint. If ink has leaked somewhere, wipe it off immediately, do not leave it for later.
The tubes of the CISS loop must NOT be bent or pinched.
If you installed CISS on your own, or an inexperienced master did it, then it is quite possible that during the installation of the system you incorrectly positioned the loop. The tubes are made of a fairly soft polymer material so they can bend easily or pinched by harder objects (for example, a case cover, carriage, or scanner assembly). As a result, defects appear on the prints, and air jams form in the tubes.
CISS air filters need to be changed as soon as they change color.
Many people simply overlook the problem of air filters, which are colored in the color of a particular dye. And this is in vain. The fact is that these elements play a very important role in the functioning of the entire NPP system. If they get very dirty, it will not let the air through. In turn, ink will NOT flow to the print head. To prevent this from happening, periodically clean the filters, or rather change them for new products. You can buy an air filter for CISS for a modest 15 rubles, the kit will cost 60-120 rubles, depending on the type of printing device.
Which ink is suitable for continuous ink supply system
The ink supply system, although it is designed to save money on consumables for inkjet all-in-one printer, is very demanding on the quality of ink. To ensure that prints always meet all international quality standards, CISS should not be refilled with old ink. If a can of paint, which was opened more than 6 months ago, has not yet been used up, it is better to throw it out and buy a new one with fresh ink.
The problem is that due to prolonged downtime, the ink in the can begins to lose its properties. This leads to a decrease in print quality, contamination of CISS, cartridge and printheads. As a result, you will have to clean the CISS more often, carry out a deep cleaning of the PG (Head cleaning), which will cause a large waste of ink and clogging of the absorber (diaper) of the printer. In addition, the ink contained in CISS donors is not advisable to use longer than 8 months. It also threatens negative consequences for the printing device and its components.
In what cases it is necessary to pump the CISS
Printing device malfunction is not always caused by problems with the continuous ink supply system. However, CISS will clearly need to be pumped when the following negative signs appear:
- One or more colors are poorly displayed during printing (fading). This indicates that there is little dye left in the store or air formations have appeared in the plume. Check CISS, refills and pump ink through tubes.
- The printer does NOT print one or more colors at all. Most likely, voids have formed in the printhead capsule or cartridge due to the presence of a large amount of air. Filling of CISS reservoirs and pumping ink will help.
- Formation of large voids in the CISS loop. If the tubes are almost half filled with air, then the CISS must be pumped. In addition, it does not hurt to check the tightness of the system, perhaps a hole has appeared somewhere.
Please note: CISS definitely should not be in a hurry to pump if you notice small air locks in the tubes of the ink plume (up to 5 cm). They usually appear due to the raising of the system containers above the level of the printer (for example, during cleaning). Over time, they themselves will disappear. If the formations increase, it means that the tightness of the CISS is broken. Eliminate the cause, by right containers and pump the ink through the system.
How to bleed CISS printers Epson
Many Epson all-in-one printer users install a continuous ink supply system on their machines. During its operation, air can begin to accumulate in the loop tubes. To eliminate the problem, the CISS of the Epson printer needs to be pumped. This can be done by the following methods:
Through the hole connecting the CISS shut-off device with the print head
To evacuate air, all container valves must be closed and the cartridge system disconnected from the printheads. Next, you need to place the PZK unit so that the ink supply holes in the SG are on top. After that, a syringe is inserted into the hole of any color, with the missing needle (the angle of entry should be about 60 °.70 °). Then, you need to open the valves of the tanks and start pumping the dye. When ink begins to flow into the syringe, and the loop is filled with dye, the openings of the CISS donors should be closed again. Now you can remove the syringe, insert the cartridge assembly into the printer and create a test print. If necessary, this procedure can be repeated with each refillable cartridge.
Through the air or filling hole of the shut-off valve of the CISS
At the top of each CISS cartridge there is an air valve closed with a rubberized stopper. It is necessary to close the holes on the donors of the NPC system and gently pry and remove this cap on the corresponding shut-off valve of the cartridge block. Insert the syringe tightly and in the same way as in the first case, pump the ink along the train. Then close the valves again to restore the tightness of the system.
Attention: In no case, do not pierce the caps covering the filling hole of the CISS shut-off valve. If you do this, then break the tightness of the system. Ink will start to flow through the print head and the printer is dirty. Or printing will not be carried out at all, since the dye will NOT reach the PG.
How to bleed Canon printers CISS
Bleeding the NPC system in Canon printers is a little more difficult than in Epson. But the problem is not in the process itself, but in the need to determine the type of printing apparatus. After all, Canon has an all-in-one printer with cartridges with a standard head, and there are models in which the steam generator and consumables are installed separately from each other. This must be taken into account before proceeding with the pumping of the dye in the CISS of the Canon printer.
Bleeding CISS in Canon printers with cartridges with a standard print head
It is possible to get rid of unwanted air in such an NPH system with several effective methods:
- Initially, you should close all the holes on the donors of the CISS. Then pull the cartridges out of the printer and disconnect the ink supply system from them. Next, you need to fill the printer cartridges in the classic way (through the holes in the lid, fill the cartridges with paint of the appropriate color with a syringe). The next thing to do is to pump the ink through the CISS loop. To do this, open the air valves of the tanks and slightly Lift the donors. The paint should begin to fill the tubes of the ink plume. If it does not work, then insert the syringe from the side of the L-shaped fittings and manually pull the ink along the train.
Please note: Typically, in an air pressure pump system with classic cartridges, air in the tubes appears due to a broken seal. Check all CISS connections with consumables, as well as cartridges for mechanical defects (chips, cracks).
- Buy a special holder for cartridges (platform, clip) and use it to pump ink along the feed system loop. This device greatly facilitates the pumping of the dye, since it is not necessary to disassemble the entire HPC system. To carry out this process, you just need to pull out the cartridges from the printer, select the required consumable, and insert it into the holder. Next, you need to return the device to you with the print head, connect a syringe to the clip hole and stretch the ink along the loop. If necessary, repeat the process for the second cartridge. The disadvantages of this method include overspending of the dye, due to uneven stretching along the train.
When you do any of the above, connect the CISS cartridges to the printer and create some test prints.
Bleeding CISS in Canon printers with separate cartridge and print head
Such continuous ink systems can also be pumped in a number of different ways. In particular, we are talking about the following:
- The first way of pumping is the same as in the previous case. It is necessary to close the covers of the donors of the CISS, and remove the cartridge block from the printer. Next, you need to disconnect the Ink plume, open the valves and stretch the ink through the tubes. Close the valves again and move the system aside. Now you need to take the cartridge block, and on each container, carefully remove the cap from the filling hole. Refuel the cartridges of the CISS block. Once the ink stores are full, you need to assemble the system and connect it to the printer.
- The second way seems to be the easiest. To do this, you just need to get the cartridge block out of the printer, open the air valves and lift the donors. CISS tanks should be somewhere 20 cm above the cartridge block. It remains only to wait for the ink to be pumped by gravity through the tubes of the system loop. However, it should be borne in mind that this method is quite easily soiled. The problem is that the coloring matter does not flow evenly. When one of the colors reaches the end point, the second will still be somewhere on the way. Therefore, in order to prevent ink from leaking, the outlet will have to be closed with something quickly. You can make homemade lids, but it will be faster to close the hole with your fingers.
Upon completion of the work, Assemble the block of CISS cartridges with a printer and print a few test pages to make sure the system is working.
Printer ink: instruction for dummies
A variety of inks, and most importantly, their names can confuse any user. over, manufacturing companies do not particularly bother explaining the strengths and weaknesses of this or that type of ink. In this article, we will try to shed some light on this issue, explain exactly how the most common types of ink work and for what purposes they are most suitable. We hope this quick guide will give you a better understanding of the ocean of printing technology.
Liquid ink. Perhaps the most common type of ink, due to the fact that inkjet printing uses just this type of ink. The most demanded and affordable today. Inkjet ink is not much different from ink used in conventional fountain pens. Inside the printer, ink, through small holes called nozzles, is applied in various ways to the print head, which “draws” dots on the paper to form a finished image or text. In cases where high print quality is of paramount importance, for example when printing photographs, so-called water-soluble ink is most often used. There are two main problems with this type of paint. Firstly, it has the unpleasant property of spreading over the paper, distorting the image, and secondly, it quickly fades in the sun, the image becomes pale and may disappear altogether. The first problem can be solved by using special paper for printing. INKSYSTEM offers its customers paper that, due to its composition, absorbs less moisture. This allows the ink to dry faster and sharpens the outline of the image. To solve the second problem, it is better to use pigment ink, which does not use water as a solvent, but most often alcohol. Pigment based inks are less prone to fading and water washout. In addition, there are also special types of paper, which, when combined with pigment inks, will make your prints almost forever. The assortment of our company includes inks and photographic paper of all types and price categories.
Solid ink. This type of ink was once developed by Tektronix, which was eventually taken over by another printing giant. Xerox company. It is this company that today produces printers that print using this technology. Such printers cost a little more than laser ones, while the print quality is significantly inferior to inkjet printers. But for certain tasks, such printing devices are quite suitable, and the minimum cost of their maintenance and absolute reliability in operation makes them indispensable for office equipment.
Toner. This type of ink is used in laser printing. Such “ink” is made by creating a polymer from a pigment and subsequent processing into a fine powder with special electrostatic properties. The use of laser printing is ideal for text documents and vector images. A laser printer prints at a tremendous speed compared to inkjet printers. Images printed with toner will not fade. However, photos printed on a laser printer look unnatural. For such purposes, it is better to use inkjet printers.
Today, the printing equipment market is so diverse that it is difficult for even an experienced user to decide which printer will suit him best. INKSYSTEM specialists will help you navigate the ocean of printing technology and suggest the ideal solution.
