Emergency Measure) Cleaning the Print Head Surface

When dot drop-out or dot deflection 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.

Procedure
  1. Referring to 1. Clean the print heads., move the print-head carriage to the left end.
  2. Apply a large amount of cleaning liquid to the cleaning stick.
    IMPORTANT

    Be sure to use one of the included cleaning sticks.



  3. Very gently touch the cleaning stick against the print head surface (nozzle surface).
    Very softly press the cleaning stick against the print head so that cleaning liquid soaks into the print head surface (nozzle surface). Never rub the stick on the surface or press it forcibly.
