In winter, due to the cold weather, some parts of the UV printer may undergo subtle changes, causing some strange failures, such as the printer head crash. These failures are not only time-consuming and costly to repair, but also affect production. Progress. This shows how important the maintenance of flatbed printers in winter is. This winter has come, have you made a plan for machine maintenance?
Micolorprint flatbed printers will tell you three reasons for the common print head collision phenomenon in winter.
A. There is a foreign body inside the UV printer.
For newly-purchased printers, users are not very familiar with flatbed printers, and the packaging materials are not completely removed, and this phenomenon is most likely to occur. Therefore, the newly purchased machine must remove the protective material of the outer packaging according to the requirements of the user manual.
B. The lubricating effect of lubricating oil is weakened.
Due to the cold and dry winter, the UV printer works in a dry environment, and the ambient temperature is too low, which will weaken the lubricating effect of the lubricating oil on the printer carriage rails, resulting in increased friction when the carriage moves on the rails. It will be prone to the phenomenon of the print head hitting.
C. Excessive dust on the flatbed printer.
Due to the heavy wind and sand in winter, too much dust falls on the UV flatbed printer, causing the friction of the carriage on the guide rail to increase, and the phenomenon of the print head hitting.
According to the analysis of the above reasons, if you want to avoid the phenomenon of print head hitting, you must maintain and maintain it from the source of the failure. Let’s talk about the items that need to be paid attention to in daily maintenance.
1. When using a flat-panel UV printer in winter, place the machine in a normal working environment. It is advisable to ensure that the operating room maintains an ambient humidity above 25 degrees, the temperature is between 10-35 degrees Celsius, and the relative humidity is 20-80. %; If the equipment is not used for a long time, the ink should be drained and cleaned with a special cleaning fluid to keep the ink head unblocked.
2. Use the three-phase power plug correctly to ensure that the power supply of the equipment is properly grounded.
3. Static electricity will interfere with the normal operation of the equipment, and the ink output from the ink head will be unstable. In severe cases, it can cause the motherboard and the ink head to be burned. Therefore, it is necessary to prevent electrostatic interference. Before operating the printer, the operator should wash his hands clean and strictly follow the operating procedures in the manual. Once electrostatic interference occurs, stop the operation immediately and check the current working environment.
Micolorprint reminds you to pay attention to the daily maintenance of UV printers in winter and to take good care of your own machines. Only by paying attention to detail maintenance can you avoid some annoying machine failures and prolong the service life of your flatbed printers.
