Print Head Check before Printing

Performing a Nozzle Drop-out Test

Before you carry out actual printing, perform a printing test to ensure 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
When performing printing tests successively, you can select [Feed] (vertical printing) or [Scan] (horizontal printing) as
the printing position for the second and later tests in comparison to the first test.
