Emergency Measure) Cleaning the Print Head Surface

When dot drop-out or dot displacement is not improved even if cleaning is performed several times, you can clean the surface of the print heads as an emergency measure. The print head surface (nozzle surface) is a very delicate mechanism, so work must be performed carefully and cautiously.

This operation is an emergency measure. It may damage defect-free parts depending on the symptoms, worsening the symptoms. If you have any questions, contact your authorized dealer.

CAUTION

Do not perform cleaning immediately after printing has finished. (Wait approximately 15 minutes after printing finishes.)

The area around the UV-LED device is hot and may cause burns.

WARNING

Be sure to perform operations as specified by the instructions, and never touch any area not specified in the instructions.

Sudden movement of the machine may cause injury or burns.

IMPORTANT

Important notes on this procedure

  • Before performing this operation, remove any objects.
  • To prevent the print heads from drying out, finish this procedure in 10 minutes or less. A warning beep sounds after 10 minutes.
  • Never use any implements other than the included cleaning sticks. Cotton swabs or other lint-producing items may damage the print heads.
  • Do not use cleaning liquid other than the included cleaning liquid.
  • Be sure to use new cleaning sticks. Reusing cleaning sticks will adversely affect the printing results.
  • Do not put a cleaning stick that has been used for cleaning into the cleaning liquid. Doing so will deteriorate the cleaning liquid.
  • Never rub the print head surface (nozzle surface).
  • If you use up the cleaning sticks or cleaning liquid, contact your authorized dealer or visit our website (https://www.rolanddg.com/).

When a warning beep sounds during cleaning

  • A warning beep sounds 10 minutes after operation starts. Stop work, close all the covers, and then tap Finish All to end the manual cleaning mode. After that, restart the procedure from the beginning.
