Printer core fault

Printer is an indispensable equipment in modern information technology, which can complete the output task of various materials such as words and images. However, in the process of long-term use, the printer will also have various failures, one of which is the failure of the printer core. So what is the printer core fault? How did this failure happen?

The print head of a printer usually consists of a magnetic core, a coil, a transmission rod and a nozzle. Among them, the magnetic core is one of the core components of the print head, which is driven by the coil to generate electromagnetic field, which makes the transmission rod move and the ink or ribbon is ejected from the nozzle to realize the printing function.

The fault of the printer's magnetic core is that the printer can't eject ink or ribbon normally. There may be many reasons for this failure, among which the main reasons are iron core damage or aging, coil failure, insufficient machining accuracy of transmission rod, nozzle blockage and so on. Therefore, when troubleshooting the printer movement, it is necessary to comprehensively analyze various possible reasons according to the actual situation and take corresponding measures to repair it.

In view of the damage or aging of the magnetic core, it needs to be replaced with a new one. At this time, we should pay attention to the selection of original magnetic cores or high-quality brand magnetic cores to ensure the printing effect and service life. If the coil is faulty, it also needs to be replaced. The aging speed of the coil is relatively slow, which is mostly caused by the insufficient machining accuracy of the magnetic core or transmission rod. At this time, it is necessary to re-process and adjust to ensure the consistency of working accuracy of all components.

When the machining accuracy of the transmission rod is insufficient, the print head will not work as scheduled, resulting in nozzle blockage. At this time, methods such as cleaning nozzles can be used for treatment. In addition, after the printer is used for a long time, it will accumulate a large amount of ink or ribbon residue, which will also cause nozzle blockage. Therefore, in the process of use, it is necessary to clean and maintain the print head regularly to avoid the problem of nozzle blockage, which will lead to the failure of the magnetic core.

To sum up, the printer movement fault is a common fault, which will affect the normal work of the printer and need to be checked and repaired in time. For printer users, they should pay attention to the maintenance of the printer at ordinary times, and clean the nozzle and other parts regularly to avoid the magnetic core failure caused by excessive accumulation of ink or ribbon residue in the printer. At the same time, attention should be paid to prevent collision or excessive extrusion when using, so as to prolong the service life of the printer.
