Cleaning the print head surface 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. The print head surface (nozzle
surface) is a very delicate mechanism, so work must be performed carefully and cautiously.
Very gently touch the cleaning stick
against the print head surface (nozzle
surface).
Very softly press the cleaning stick against the
print head surface. Never rub the stick or press it
forcefully against the print head surface.
This procedure is an emergency measure. Depending on symptoms, it may damage normal areas and
cause symptoms to worsen. If you have any questions, contact your authorized Roland DG Corp. dealer.
