In the production of UV flat panel ink-jet printing, the image quality will be made wrong
due to factors such as nozzle failure, media placement and height adjustment, mainly
because the nozzle drops ink, leaks ink, or the nozzle is too close to the material medium,
causing the nozzle to brush the media surface and damage the image quality. UV flat panel
printing materials must be placed flat, which will be much better for equipment with air
suction device. Of course, another reason is that the printing material is too transparent
or too thick. At this time, you need to reload the printing materials to ensure the smooth
surface, and replace the opaque printing materials.
Occasional ink drops occur during UV flat panel ink-jet printing. This is usually because
the filter in the air filter on the secondary ink tank is wet, resulting in poor ventilation.

This may also be caused by dirt such as fine hair and dust on the UV flat panel ink-jet
printing head. When these dirt accumulates to a certain extent, the ink sprayed by UV
ink-jet will automatically drip. To solve this problem, the air filter needs to be replaced,
and the nozzle needs to be cleaned with special cleaning solution. A detailed inspection
should be carried out on the two edges of the light box cloth to see if there is any extra
burr. If there is any burr, it can be simply handled with a lighter.
After the printing data is transferred, the indicator light of UV flat-panel ink-jet printing
will keep flashing. Even if the Start key is pressed, UV flat-panel ink-jet printing still cannot
be printed. This is also a common fault in the production of UV flat panel inkjet printing,
which is difficult for inexperienced operators to handle.
It should be noted that if the UV flat panel inkjet printer performs an incorrect print termination
operation during the printing process, even if the printing work is stopped, there will still be
some residual print data transferred to the inkjet printer, and the print data is still retained in
its memory. However, in the view of the UV flat panel inkjet printer, the data is invalid, and
the printing work cannot be realized, It will also cause the subsequent printing work to be abnormal.
