Due to the powerful functions of the UV inkjet printer, it is determined that the internal structure of the UV printer is very complex, and the UV digital printer's own maintenance and operating environment requirements are very high, and the requirements in terms of operation are also very strict. However, after analysis, it was found that the handling of multiple faults is very simple. Let me share with you friends the quick solutions to these glitches.
The cause of the failure: the ink quality is poor or expired, the air in the ink tube is not exhausted, and the nozzle line is loose and falls off.
Trouble shooting method: Pour off the problem ink, inject the high-quality ink within the warranty period after cleaning, reinstall the ink tube to exhaust the air, and reinstall the nozzle line.
The cause of the failure: the length of the printing operation of the UV printing machine is not correct.
Troubleshooting method: adjust the access sensor blank.
Cause of failure: The motherboard is damaged.
Troubleshooting method: replace the motherboard.
The cause of the fault: the board is set incorrectly.
Troubleshooting method: modify the settings of the board, you can ask the relevant settings of the manufacturer.
The cause of the failure: There is a problem with the installation of the nozzle cable, or the front sensor is damp or damaged.
Troubleshooting method: correctly install the cable without problems, check and maintain the front sensor.
The cause of the failure: dirt on the grating strip and the nozzle.
Troubleshooting method: cleaning and maintenance of grating strip and spray head.
The cause of the failure: the nozzle cable has been damaged
