  8. Printhead clogging

  A

  Possible reasons: UV flatbed printer’s clogging is mostly caused by contamination precipitation. Another possible cause is the strong curing ink that cures on the surface of printhead. Solution: If the ink supplying system and printhead’s clogging are caused by don’t use the printer for a long time or don't uses original ink, it is better to cleaning the printhead. If can’t solve the problem, you can only take down the printhead, soak it in 50 °C ~ 60 °C clear water and clean it with ultrasonic cleaner. After the cleaning process, you can reuse the printhead after drying.

  9. The speed of the carriage become slower

  A

  Possible reasons: the speed of the carriage become slower, then the print speed comes down. The continuous ink supply system will inevitably increase the burden of the carriage. The carriage will become slower when holding too heavy load. At the same time, the heavy load will accelerate the aging process of the belt and increase the friction between the carriage and connecting rod. These are the possible causes why UV printer’s print speed becomes slower. In severe cases, the carriage can’t reset, and then can’t use. Solutions: Change the motor. The friction between the continuous ink supply system rubber tube and printer’s body will increase the burden of the motor. It is suggested to change new motor after a long time of using. Lubricate the connecting rod. After a long time of using, the friction between the carriage and connecting rod will increase, and then decrease the motor’s running speed. Lubricating the connecting rod can solve this problem. The friction increase between the motor’s gear and printer’s belt，which will increase the belt’s aging process. This problem can be solved by cleaning the gear and lubricate it.

  10. Printer doesn’t print

  A

  Possible reasons: This situation is very common among users who use CISS. The printer does not print after a period of time. Solutions：the main cause of this situation is that UV flatbed printer’s waste ink tank is full. Actually each UV flatbed printer has fixed life span setting for each component part. When some components reach the set life span, the printer will stop working. When using CISS, waste ink easily comes out, this will cause waste inkbottle easily become full. So clear the waste inkbottle at once will solve the problem.

  11. Maintain the suction pump timely

  A

  Possible reasons: In reality, suction pump’s performance and air tightness will drop because of long time use and the increase of dust and ink residues. If the operator doesn’t check and clean the suction pump regularly, the UV printer’s printhead will constant have problems like clogging, so it is necessary to maintain the suction pump timely. Solutions: Remove the UV printer’s top cover and carriage; clean it with cleaning solution with syringe, pay more attention to the Microporous gasket while cleaning. Important notice: you should never clear this part with ethanol and methanol; otherwise Microporous gasket will dissolve and become distorted. At the same time, please don’t let the lubricating oil touch with the cleaning pump’s nozzle. Oil will distort the sealing rubber beside the cleaning pump’s nozzle and then it can’t seal and protect the printhead.
