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

Care and Maintenance When Uneven Color Occurs

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)

with uneven colors.)
