Care and Maintenance of the Print Heads

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.
Daily care and maintenance

We recommend performing a printing test and normal cleaning before day-to-day operation.

Maintenance procedures in the event of uneven color issues
 Light choke cleaning
Perform this procedure when printed colors are unstable or uneven, e.g., when color density is inconsistent,
even if the same data is printed with the same settings.

 Refreshing subtanks (REFRESH SUBTANKS)
Use this procedure when light choke cleaning does not resolve uneven color issues. (Note that it is neces-
sary to perform this procedure once every six months regardless of whether or not there are problems
with uneven colors.)

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.
