How to solve the problem that the head of the UV flatbed printer cannot flash?

Table Of Contents

With the deepening of research and development technology, there are more and more heads and types of flat-panel printers, and the industries that are used are more and more extensive. Now, the most mainstream is the dual-jet UV printer. The most important part of a printer is the head. However, the most common failure of a flatbed printer is also likely to occur in the head.

How can we reduce the occurrence of the common failure of head clogging? 

Manufacturers have taken this aspect into consideration when designing and assembling printers. Therefore, the current print heads all have the function of flashing. In order to prevent the ink from clogging the print head, the print head will spray some ink at regular intervals to keep the print head clean. This is a flash jet. We know that the most fear of the head is dryness, so the head must be kept moist when the machine is not working. There is solvent in the ink of the flat UV printer. The solvent evaporates at the head of the head and the ink solidifies at the head hole, which will block the head. Flash jet is to eject the ink quickly in this case to wash away the solidification and keep the head moist. If the head cannot flash, it will block the head severely if it takes a long time.

What is the reason why the head cannot flash? how should I solve this?

        In fact, this problem is very easy to solve. The problem of the inability to flash spray is mainly due to the problem of the optical transmission line. We all know that the optical braze is a very easy-to-damage item, it is easy to break, and can not bend. Therefore, we must be very careful when using, replacing, and unplugging. If the printer head cannot flash, the first thing we have to consider is to plug in the optical fiber first to check whether the signal is normal, and if can it be flashed during printing. If it can, continue to use it; if it doesn’t, you can only replace it with a new optical fiber transmission line. Under normal circumstances, the flash spray can be achieved after replacement. If it still does not work, you need to call the manufacturer’s after-sales phone to seek technical support.
