Maintenance that Should Be Performed Weekly
When dot drop-out and/or dot de ection is not improved even if cleaning is performed several times,
you can clean the head surface as an emergency measure. Since the head surface (nozzle surface)
has an extremely delicate mechanism, make sure to perform the operation carefully and deliberately.
Note that this operation is an emergency measure. It may damage defect-free parts depending on the
symptom, deteriorating it. If you have any questions, contact your authorized Roland DG Corp. dealer.

Cleaning of the head surface as an emergency measure

Press it gently and softly so that the head nozzle is permeated with the cleaning uid.
Never rub the stick on the surface and press it forcibly.
