Print Head Maintenance Guide

The print head is the most necessary part of the printer, and may also be the most vulnerable part. The print head is a kind of consumable, just like the brakes on the car will eventually be worn out over time. However, if the print head is maintained continuously and carefully, the service life of print head can be extended.

To maintain the best performance of the print head, it is recommended to clean the print head after a roll of thermal transfer ribbon or a roll of thermal printing ribbon is printed. Pay special attention to removing substances that may scratch the print head before handling and cleaning the print head, and use anti-static rings or anti-static pads to release static electricity that may damage the print head.

Try to reduce the premature damage to the print head caused by the following factors

Wear --- the print head is damaged due to friction, which may also be caused in normal use. Wear is usually minimized by good maintenance.

Pollution --- such as dust will cause damage to the print head.

Erosion --- progressive damage to the print head may occur due to paper and incorrect cleaning.

ESD --- electrostatic damage caused by unreasonable operation and environmental factors.

Damp --- the printer will cause damage to the print head when used in a damp environment.

Adhesion and fouling of back coating - the dirt accumulated by unreasonable maintenance, cleaning, inferior consumables, and other factors will lead to the decline of print quality, such as weak printing or local printing defects.

Method of cleaning the print head

1. Carefully remove the print head, remove the ink cartridge and cover, carefully observe the print head, find out the position of the nozzle and orifice, and find out the degree of blockage.

2. Routine cleaning: if the nozzle is not blocked seriously, connect one end of the hose to the ink inlet of the print head. When the hose is sleeved on the ink inlet, there should be a certain tension, that is, it should not be too loose, otherwise the water in the hose will overflow when pushed. Put a syringe full of water into the other end of the hose and gently push the syringe first. At this time, you can see the sewage overflowing from the nozzle. Repeated cleaning of each nozzle can make the nozzle unblocked.

3. Special cleaning: sometimes the nozzle is blocked seriously, and the sewage can not be seen overflowing from the nozzle when pushing the syringe. Carefully observe the nozzle with a magnifying glass, and you can see that a large number of residues are deposited on the edge of the nozzle. At this time, "dredging surgery" must be performed. The method is: to use the end of a rubber hose cut into a sharp slope (be careful not to use a hard pipe), and gently clean the spray hole until clean water is sprayed from the spray hole.

Some users do not pay attention to the useful skills of inkjet printers, nor do they maintain inkjet printers. This will inevitably cause some problems for the printer. Therefore, it is necessary to master some daily use and maintenance skills of inkjet printers to avoid some problems.
