W hen Dot Drop -outs/Uneven Colors Are Not Fix ed
Cleaning of the Surf ace of the P rint H eads as an Emergency Measure
When dot drop-out or dot de ection 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.
Note that this operation 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.

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 or press it forcefully against the print head surface.
