If your machine tests well, then there will definitely be no quality issues. Within 3 months from the date of receipt, we can accept returns for any problems caused by non-human damage.

Precautions for print head installation:

1. ofnozzleofheadVery fragile, do not crash. It must be protected. Its surface is a block of aluminum coated with a crystal oscillator and very thin ink tubes. It will be dented, deformed, or even broken when in contact, causing the nozzle to be scrapped;

2. Be careful when installing the nozzle. Be sure to turn off the power and put it in place. After installation, gently push the trolley to move left and right to check whether it is smooth. Do not turn on the power after installation, because if the machine head is not in place, it is easy to break the machine head when the trolley moves, and the hand feels free. , strong controllability;

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

4. The steel shaft should also be clean and smooth. Can be wiped with paper towels and glued on. Do not add oil directly to the shaft. Excess oil can flow into the nozzle and cause damage.

5. After the machinery and circuit are correct, the waterway needs to be checked. First check whether there is insufficient water in the ink cartridge. Secondly, check whether the small cleaning blade and ink suction pump are dirty.

6. There is air inside the newly installed nozzle, so it cannot print normally immediately. Only when the air in the head is completely exhausted can the circuit be normal;

First of all, intermittent cleaning (only cleaning twice at a time, stopping for 2 minutes and then cleaning for 30 minutes) will cause excessive cleaning multiple times, causing ink to accumulate in the cleaning pump, which will not only cause the printer to mix colors, leak ink, but also waste ink. ;

Secondly, you can print more pictures and let the nozzles discharge air when working;

Thirdly, if there is a waste ink tube in the machine, you can cut off the power first, then cover the rubber tube with a syringe and pump air into the ink tube until 3-5ml of ink is extracted.

Then turn it on again and clean it with a machine, which is equivalent to manually extracting the air from the head. The side effect is that it is easy to cause accumulation in the cleaning pump.
