Care and Maintenance of the Print Heads
Care of the print heads is essential to ensuring optimal printing at all times. There are maintenance tasks that
should be performed daily and those that should be performed periodically.
Daily Care and Maintenance
Printing tests and normal cleaning
We recommend performing a printing test and normal cleaning before day-to-day operation.
P. 40, "Printing Tests and Normal Cleaning"
Periodic Care and Maintenance
Medium cleaning/powerful cleaning
Perform medium cleaning or powerful cleaning when problems such as dot drop-out are not corrected
after performing normal cleaning.
P. 56, "Medium Cleaning", P. 57, "Powerful Cleaning"
Manual cleaning
Perform manual cleaning periodically according to your frequency of use.
P. 61, "Manual Cleaning"
Refreshing subtanks (REFRESH SUBTANKS)
Perform this procedure once every six months. (This procedure is eective when light choke cleaning does
not resolve uneven color issues.)
P. 67, "Refreshing Subtanks (REFRESH SUBTANKS)"
Care and Maintenance When Uneven Color Occurs
Light choke cleaning
Perform this cleaning 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.
P. 58, "Light Choke Cleaning"
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.)
P. 67, "Refreshing Subtanks (REFRESH SUBTANKS)"
Note: The print heads are components that wear out. Periodic replacement is required, with the frequency of
replacement depending on use. Contact your authorized Roland DG Corp. dealer.
