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.Performing Printing Tests Arranged Horizontally

    IMPORTANT Depending on the media, locations on which optimizer ink is printed may be difficult to check. If it is difficult to see the optimizer ink, switch to a different media and perform the printing test again.

    If no dot drop-out or dot displacement occurs, this operation is finished. Press AP-640_Panel_Icon_HOME to go back to the original screen.
