Analysis of three misunderstandings of cost reduction ink injection

myth 1: ink cartridges can add ink without limitation

many people believe that ink cartridges are just a container for ink. As long as the surface of ink cartridges is not broken, they can continue to add ink. In fact, this is another big mistake

first of all, the sponge in the ink cartridge has a certain life. When the sponge repeats the process of "absorbing releasing" ink for many times or uses it for more than a certain period of time, the ink absorption capacity of the sponge will be reduced. In this way, the ink filled into the ink cartridge will not be completely absorbed by the sponge, and the pressure of the ink in the ink cartridge on the nozzle will increase, causing the ink to flow out of the nozzle. This is one reason why many people complain that the printing volume of refilled ink is not as good as that of original ink

what is more serious is that the printer cannot monitor this part of the ink flowing to the waste ink pad, so the actual amount of waste ink in the waste ink pad may be much larger than the amount of waste ink monitored by the printer, so when the printer has not sent out the waste ink excess alarm, the waste ink has overflowed, causing damage to the printer

secondly, a rubber sealing ring is used between the ink cartridge and the ink inlet of the nozzle to ensure that the ink cannot leak out. Long term use or multiple removal of the ink cartridge will aging the sealing ring and deteriorate the sealing effect, resulting in the leakage of ink from the joint, and the thinning of the bumper wall thickness is a general trend. This will make the ink accumulate and mix on the nozzle, resulting in the color mixing of the bottom ink. The direct result is that the color changes when printing drawings, and the color can return to normal only after printing multiple drawings. This situation will also lead to a waste of ink and an increase in the amount of waste ink from the printer

third, no matter how well the ink is filled, some impurities or dust will be brought into the ink cartridge after multiple filling. These dust will be carried to and adsorbed on the filter of the ink cartridge when the ink flows. With the increase of dust, the filter of the ink cartridge will be blocked, resulting in poor ink flow, which will cause problems such as disconnection during printing. If the filter is completely blocked, there may be failures such as failure to print

therefore, when the ink is filled for more than ten times or one cartridge is used for more than one year, it is best to consider replacing it with a new cartridge to avoid various problems

Myth 2: the waste ink volume of the printer is too large, which can be cleared by program.

recently, the problem of waste ink volume before ink injection of the printer has also been discussed very warmly in various forums. Many friends think that after the waste ink volume is exceeded, you only need to run the printer maintenance program and clear the printer waste ink counter

in fact, the method of clearing the waste ink in the maintenance program is just that this method includes spraying a chemical material - called reflectin - to remind the squid of its pretending ability to clear the waste ink counter in the printer on the sticky surface containing graphene. The waste ink produced by the printer due to nozzle cleaning, power on self-test and other reasons still exists for this. If we just clear the waste ink counter without cleaning the waste ink pad of the printer, the waste ink in the waste ink pad will continue to increase while the printer continues to work. Once the waste ink pad of the printer is filled with waste ink, waste ink may flow out

if these waste inks flow to the printer's power board or control board, it will cause a short circuit on the circuit board, resulting in damage to the printer. Even if the waste ink does not overflow, when the waste ink of the printer is excessive, the steam volatilized from the waste ink pad will damage the printer circuit board, action mechanism and even the nozzle

of course, some friends think that when the printer waste ink volume warning, the waste ink in the waste ink pad is not full, and there is no need to clean the waste ink pad. Indeed, in many places (especially in high-temperature areas in the South), when the printer waste ink alarms, there is not much ink on the waste ink pad. In addition, there is a certain margin left for the printer alarm, so it gives many friends the impression of "no danger". But we can't take this as the reason why we don't need to clean the waste ink pad, because the amount of waste ink on the waste ink pad has many variables, such as the temperature, the air humidity, whether the printer has ink leakage, etc. Moreover, even if the waste ink doesn't overflow when the waste ink alarm is given for the first time, what about the second and third alarm

the author here suggests whether the manufacturer should consider changing the design and moving the waste ink cartridge out of the printer to avoid waste ink spilling and damaging the printer

myth 3: using permanent chips can keep the printer from washing the nozzle and save ink

with the promotion of continuous supply system, the permanent chips of printer ink cartridges have also been adopted by many friends. Nowadays, permanent chips generally have two functions: first, there is no need to decode. As long as the printer is turned off, the counter on the chip will be cleared, making the printer think that the ink in the ink cartridge is full. Second, no nozzle cleaning, that is, the printer does not perform nozzle cleaning after startup, which can save some ink

because of these advantages of permanent chips, many ordinary users who do not use the continuous supply system also replace the chips on the ink cartridges with permanent chips. However, due to the small daily printing volume of ordinary users, if the printer is not used for a long time, the ink in the nozzle will inevitably increase in viscosity or dry up due to the evaporation of water, causing blockage. This only depends on the automatic cleaning nozzle when the printer is turned on to solve the problem. After adding permanent chips, the printer will not clean the nozzle when it is turned on, and the nozzle will be cleaned only when the user finds that it is abnormal after printing. This will not only not save ink, but also cause more waste of printing paper and ink

of course, for users of the continuous supply system with a large amount of printing, because a large number of printing is required every day, the ink is brought out by the new ink before it dries up, so it is not easy to jam. However, many users report that the print quality has decreased after using the continuous supply system for a period of time. Some people have always believed that this was caused by the aging of the nozzle or poor ink, but once when cleaning the nozzle for a printer using a continuous supply system, when checking the nozzle with the method in the second serial article, it was found that although many nozzles could eject ink, the ejected ink had obvious bifurcation, and the printing quality improved after cleaning the nozzle

the reason is that there is something blocking part of the nozzle. When printing the test page, because the nozzle can also eject part of the ink, it is not easy to feel this blockage. However, this blockage will cause the ejected ink droplets to become smaller, making the coverage of the ink droplets on the paper insufficient. At the same time, it will also cause the ejected ink to fly and deflect its positioning on the paper. In this way, the printed manuscript will make people feel that the particles are too thick

the reason why the nozzle is partially blocked is related to the use of permanent chips and the printer does not clean the nozzle when it is turned on. When using permanent chips, the printer does not automatically clean the nozzle, and users do not clean it because they do not feel blocked. In this way, impurities are easy to adhere to the wall of the nozzle for a long time and become difficult to clean. When the printing effect is found to be poor, the nozzle cleaning can not bring out these impurities. Therefore, the author suggests that when using permanent chips, it is best not to choose chips without nozzle cleaning
