Daily Print Head Checks

Printing Tests and Normal Cleaning

The print heads are important components that discharge ink. They require periodic and appropri-
ate maintenance. Before daily operations, perform a printing test to ensure that no dot drop-out or
dot displacement occurs. If dot drop-out or dot displacement occurs, perform cleaning of the print
heads (normal cleaning).

• This operation is unnecessary if you will only perform cutting.
• When performing printing tests successively, you can select "SCAN" (vertical printing) or "FEED" (hor-
izontal printing) as the print position for the 2nd and later tests in comparison to the 1st test.
