Printer maintenance is a matter that needs to be taken seriously. In this process, we need to confirm many details before we can do it quickly. Today, I will share with you two details that need to be paid attention to when encountering some common problems as users or engineers.

1. Relevant details when repairing ink path problems of the inkjet printer.

If you have studied the ink path diagram of a printer, we will find that among the two core components of the printer equipment (ink path and circuit), the ink path of the nozzle is the most prone to failure.

Including pressure pumps, solenoid valves, ink outlet pipes, recovery pipes, cleaning pipes, nozzles, recovery tanks and other parts, the quick-drying ink generally solidifies within 0.3 seconds. Especially in summer or in harsh environments, once the equipment is not properly shut down or if the nozzle is not cleaned for a long time, you will face the problem of accumulated ink clogging.

When repairing and handling such problems, one of the details we should remember is that we should not rush. We need to carefully clean all the pipes involved one by one to quickly eliminate and find the real blockage. If the blockage is serious, it takes time to gradually open it up; If the nozzle is seriously blocked, an ultrasonic cleaner can be used.

2. Details related to the maintenance of abnormal typing of the inkjet printer.

After handling the ink path failure of the printer and carrying out regular maintenance, we can generally solve many printing abnormalities, but in some cases we will have no clue how to deal with it and it is difficult to repair it.

This mainly refers to the fault of the printer circuit. These details include the charging calibration of the circuit, split voltage calibration, pressure calibration, high-voltage measurement, ground wire detection, etc., and require special Detection Tools to carry out the testing and maintenance of the printer circuit, which requires relatively high requirements for equipment users and often requires technical support from the manufacturer.

To sum up, it is not difficult to see that although printer maintenance is simple, it contains many details, which require time to accumulate to obtain. In terms of mentality, we must face it up to, and when there is an opportunity, carefully study the working principles of the printer and take notes, so that you can be calm in the face of many emergencies.
