What should be pay attention to when installing the print head of Epson printer?

Epson printer print head installation issues should be noted:

1. The head of the nozzle is very fragile and must not be bumped. It must be protected. Its surface is a piece of aluminum, and the inner layer is coated with a crystal oscillator and a very fine ink tube. When it touches, it will be concave, deformed, or even broken, so the nozzle will be scrapped;

2. Be careful when installing the print head. Make sure that the power is cut off first and installed in place. After loading, gently push the car around with your hands to check whether it is smooth. Never install it and turn on the electricity. Because if the head is not in place, the car will easily smash the head when it moves, while the hands have a feeling, easy to retract and release, and strong controllability;

3. When connecting the plug cable, do not bring the ink, and make sure that it is in good contact with the socket and does not touch the foot. Otherwise, the nozzle will be short-circuited and burnt;

4. The steel shaft should also be clean and smooth. It can be wiped with a paper towel and glued. Do not directly add oil to the shaft. Excess oil will flow to the nozzle and cause damage.

5. After the machinery and circuit are correct, it is necessary to check the waterway. First, look at the insufficient amount of water in the ink cartridge. Secondly, check whether the small cleaning blade and the ink suction pump are dirty.

6. There will be air inside the print head that has just been installed, so it will not print properly immediately. Only when the air in the head is completely discharged can the line be normal. First, intermittent cleaning is available. (Only clean 2 times at a time, then stop for 30 minutes and then wash 2 times.) If the cleaning is excessive, it will cause the cleaning pump to accumulate ink, which will not only make the printer mix colors, leak ink, but also waste ink; secondly, you can print more pictures and let The nozzle discharges air during work; again, if the machine has led out the waste ink tube, it can be powered off first, then use a syringe to cover the rubber tube to evacuate the ink tube until the 3-5ML ink is extracted, and then turn on the machine. The machine is cleaned normally, which is equivalent to artificially pumping out the air in the head. The side effect is that it is easy to cause the cleaning pump to stack ink.

There are many places to pay attention to the print head, so blind replacement by non-professionals can cause human damage. There is a rule in the line, the nozzle is not guaranteed, if you are not familiar with the machine, it is recommended to find a professional to replace the print head, so as to avoid unnecessary losses and trouble!
