As long as the machine is bound to have faults, as a multi-function printer, the garment digital printing machine must also have some common faults. REHOW Textile Machinery will take you to understand the ten common fault causes and solutions of the garment digital printing machine. You save a lot of unnecessary trouble!
1. Broken ink
Phenomenon: In the process of s digital printing, some nozzles do not produce ink.
Causes: Blockage of the nozzle channel, improper setting of the nozzle working voltage, blockage of the ink sac, ink problems, and improper adjustment of the negative pressure will all lead to ink breakage.
Solution: lower the height of the trolley, prevent the fan or air conditioner from blowing directly to the work area, avoid strong drafts in the workplace, change the material, and recalibrate the nozzle.
2. The effect of printing pattern is poor
Symptoms: Blurred picture, misaligned color coverage, ghosting.
Reasons: Improper height of the carriage, excessive distance between the nozzle and the material leads to inaccurate inkjet drop point, strong airflow affects the accuracy of inkjet drop point, poor ink absorption ability of the material,
The head is not aligned.
Solution: lower the height of the trolley, prevent the fan or air conditioner from blowing directly to the work area, avoid strong drafts in the workplace, change the material, and recalibrate the nozzle.
3. The boot car does not rebound after reset
Phenomenon: After turning on the machine and pressing the reset button, the car only leans to the right, but there is no reset, and there is no flash spray, and other operations cannot be performed.
Reasons: switch failure, car board failure, SCSI line failure, PCI card failure, servo board failure.
Solution: replace the switch, replace the car board/SCSI cable/PCI card/servo board.
Fourth, print garbled characters
Phenomenon: Irregular and unpainted sprays appear on the screen.
Reasons: Inkjet data transmission processing error, car board failure, data cable loose or failure, fiber optic failure, PCI card failure, screen processing problems.
Solution: Arrange the nozzles to test each nozzle one by one, troubleshoot the nozzle, replace the data cable (data cable of the nozzle or the data cable of the car board), replace the car
board/fiber/PCI card, reload screen for processing
5. Abnormal ink output in fixed places
Phenomenon: The screen, grating strip, and small car board are faulty.
Reason: Change the screen, change the spraying position, test the spraying effect of different screens in different positions, if other screens are normal, it proves that there is a problem with the secondary screen processing;
If there is a problem with the ink ejection in all the screens, check the grating strip; if the ink ejection problem still occurs in a certain position after changing the screen, check the small car plate.
Solution: Reload the screen for RIP processing, clean or replace the grating strip, and replace the car plate.
6. The car runs unevenly. 6. The car runs unevenly.
Phenomenon: part of the ejection screen is clear and part is blurred, and the accuracy of inkjet positioning at each position is different.
Cause: The rail girder is not leveled.
Solution: readjust the beam.
Seven, the car is shaking, and the spray painting is misplaced
Reasons: the grating strip is damaged, the leather belt is broken, and the towline is stuck on sundries.
Solution: Clean or replace the grating strip, replace the 465 leather belt, and clean the drag chain slot.
8. Crash
Phenomenon: The boot car hits the right end.
Reasons: positioning failure, grating head failure, small car board failure.
Solution: Check/replace the switch, replace the grating head, and replace the car plate.
9. The noise of the negative pressure air pump of the printer is loud
Causes: Loose air pump, clogged filter, faulty air pump.
Solution: Tighten the air pump, replace the filter/air pump.
10. The light on the car panel is off and cannot be reset
Reasons: loose wiring, car board failure, servo board failure, data cable failure.
