Why the UV flatbed printer nozzle occur poor ink ?
Symptoms of poor ink output from uv flatbed printers are: flying ink, dripping ink, drawing and so on. There are roughly eight kinds of reasons that cause this kind of failure. In actual application, the UV flatbed printer design varies from different manufacturers. Some may have 10 reasons, and some may have 6 reasons. But mastering the following 7 kinds can solve the problem that 99% of the nozzles have poor ink discharge.
1. Nozzle height is unqualified
Solution: The nozzles of different models of UV flatbed printers have different printhead heights due to different jetting forces. Only within a reasonable range of values can the printing effect be guaranteed. Too high,it is easy occur fly ink,Too low, it is easy to scratch the nozzle.
2. Nozzle blocked oblique spray
Solution: Pause the machine, clean the print head with cleaning liquid, and then continue printing. If the oblique spray is serious, you need to replace the new UV flatbed printer print head.
3.The heating temperature has not reached the set value
Solution: Especially in winter, when the temperature of the UV flatbed printer’s nozzle needs a heating device for smooth ink discharge, check whether the heating device such as the heating plate has reached the specified temperature value.
4.Nozzle voltage abnormal
Solution: Check whether the voltage plate of the UV flatbed printer nozzle is faulty, if necessary, replace it with a new one.
5, ink expired, precipitation, etc.
Solution: See if the expiration date of the outer packaging expires, and shake the ink bottle, whether it is the sound of rushing water. Expired, precipitated and solidified, you need to replace with new UV ink.
6, flat line aging
Solution: Replace the new flat cable and install it.
7. Nozzle board failure
Solution: If the nozzle plate of the UV flatbed printer is faulty, you need to contact the original equipment manufacturer and send in a new nozzle plate to replace it.
