2.Regular Maintenance
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 operaons, perform a prinng 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).
MEMO
• This operaon is unnecessary if you will only perform cung.
• When performing prinng tests successively, you can select "SCAN" (vercal prinng) or "FEED" (hor-
izontal prinng) as the print posion for the 2nd and later tests in comparison to the 1st test.
