Causes and solutions of unsmooth and uneven ink output of uv flat panel printer.

For climate reasons, when the outside temperature is too low or too high, the uv ink

itself will be coagulated, the smoothness will be damaged, and the volatilization will

be abnormal. The external performance is that the ink from the nozzle is uneven.

Solution: When the weather is hot in summer, add an air conditioner in the workshop to

keep ventilation, and do not place the uv flat-panel printer in the direct sunlight.

When the temperature is cold in winter, turn on the heating, use the small sun to heat

the car or install a heater at the ink outlet of the nozzle. Keep the temperature of

the uv flat-panel printer between 15 ° - 40 ° and the humidity between 30% - 70%.

The reason for the printing head is that the printing hole of the printing head is blocked,

resulting in abnormal ink discharge, broken needle, missing thread, etc. The nozzle needs

to be cleaned by pressing ink, and observe whether the ink jet state has waterfall like

flowing lines. If it is not possible, the nozzle needs to be cleaned with cleaning solution.

If it is serious, the nozzle needs to be disassembled and ultrasonic cleaned after immersion.

If it is not feasible, the nozzle needs to be replaced. In the daily maintenance process,

the status chart of the nozzle needs to be printed out every day for observation.

The ink supply system fails. On many manually adjusted uv flat panel printers, the negative

pressure value is extremely low and high, which affects the normal flow of uv ink. When

this happens, it is necessary to adjust the negative pressure. If possible, the negative

pressure system can be directly upgraded to avoid this situation.
