Emergency Measure) Cleaning The Print Head Surface - Roland TrueVIS VG2-640 User Manual

Handling Severe Dot Drop-out and Dot Displacement

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 Roland DG Corporation dealer.
Procedure
1.
Apply a large amount of cleaning liquid to the cleaning stick.
2.
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.
