Cleaning of the surface of the print heads as an emergency measure
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. Since the surface of the print heads
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.
Procedure
Moisten the cleaning stick with the cleaning liquid.
Softly press the cleaning stick to the surface of the print heads.
Press it gently and softly so that the surface of the print heads is permeated with the
cleaning liquid. Never rub the stick on the surface and press it forcibly.
