When Dot Drop-out Cannot be Cleared Up

Chapter 3 Maintenance
Cleaning of the head surface as an emergency measure
When dot drop-out and/or dot deection 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)
is an extremely delicate mechanism, make sure to perform the operation carefully and deliberately.
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 Corp. dealer.
