Timing of Print Head Care and Maintenance
To keep a stable printing condition at all times, the print heads need to be maintained. There are maintenance
tasks that should be performed daily and those that should be performed periodically.
Note: The print heads are components that wear out. Periodic replacement is required, with the frequency of
replacement depending on use. Purchase them from your authorized Roland DG Corp. dealer.
Daily Care and Maintenance
 Printing tests and normal cleaning
We recommend performing a printing test and normal cleaning before day-to-day operation.
