8. Treatment of broken wire fault

Print disconnection is a common fault, which is generally caused by the following reasons:

• After the new ink cartridge is put on the machine, it only needs to clean the printing ink line once or twice.

Generally, it will not break during use. The first reason for the frequent wire breaks is that the user did not set the paper feed bracket properly before printing, resulting in paper rolling during the paper feeding process, and wire breaks after the paper rub with the nozzle.

Solution: set the paper feed tray.

The other is that when the original ink is almost used up, the new ink cartridge is not replaced in time, but the printer is placed in a high-temperature environment for a long time. Generally, an ink cartridge should be replaced immediately after it is used up within three months after installation. If the ink cartridge is replaced infrequently, the airtightness will become poor due to the air entering the ink cartridge, which is easy to increase the viscosity of the ink on the nozzle and in the ink cartridge, resulting in the disconnection of the inkjet printer.

Solution: replace the ink cartridge and clean the nozzle.

• Common problems in replacing ink cartridges of other brands

The reason for the disconnection caused by replacing other brand ink cartridges is that the physical and chemical properties of the ink cartridges do not meet the parameters required by Epson ink cartridges. When we replace ink cartridges of other brands, we sometimes find that some colors can be inked smoothly, while some colors can only be inked after repeated cleaning, which wastes a lot of ink. This is because the ink cartridges produced by such manufacturers are far from meeting the technical requirements of Epson ink cartridges, and the ink delivery imbalance is most likely to occur during use.

The original ink cartridge has made an article on the chemical characteristics of ink and the adjustment of air pressure and pressure of the box. However, some other brand ink cartridges do not understand its principle, so the difference between the ink cartridges made is large, so it is difficult to achieve the balance of ink flow. What is more serious is that some ink cartridges have too much-dissolved matter from the sponge, and the sponge has a too large an expansion coefficient when encountering ink. The stainless steel ultra-fine filter screen used at the ink outlet cannot meet the requirements. It is reasonable that such ink cartridges cause failures in the printer.

Solution: use the original ink cartridge.

• Problems with inking the ink cartridge

Common faults of ink cartridges after ink injection are broken wire, plug, and inaccurate chromaticity.

If the physical and chemical properties of the ink you inject are similar to the residual ink in the original ink cartridge, it is completely usable. Because we manually add ink under atmospheric pressure in the air, it is impossible to master the ink injection amount of different colors. There will be more bubbles in the added ink molecules. At this time, do not rush to use the ink cartridge immediately after it is installed, but turn off the printer after cleaning the nozzle once or twice. The machine needs to be shut down for about 2-6 hours before use. At this time, the ink in the ink cartridge will be automatically vented due to chemical exhaust, and the bubbles and air have been discharged to the top of the ink cartridge, which can reduce the failure when you reuse it.

The plug is the most likely problem after ink injection because the ultra-fine filter screen of the Epson inkjet printer is designed at the ink outlet of the ink cartridge, while there is no filter screen at the interface between the ink outlet of the nozzle and the ink cartridge. Some people reverse inject ink into the ink cartridge at the ink outlet of the ink cartridge, which is easy to causes dust and impurities to enter the ink outlet, thus making the printer plug.

Another kind of chemical plug occurs because the chemical properties of the injected ink are different from those of the residual ink in the original ink cartridge. The chemical reaction process of different inks is slow, which is very difficult to observe with the naked eye. If the ink stays on the nozzle and reacts, it will cause destructive consequences to the nozzle.

Another common problem with replenishing ink is that the color is not very accurate. The production of color materials will have a color difference due to different batch numbers, which is also the most difficult step in the production of color materials. For the supplementary ink of the Epson inkjet printer, in case of chromaticity deviation, the user can adjust it in the attribute set of the Epson inkjet printer, as long as the adjustable range is within the range that can be set by Epson software.
