Powerful Cleaning Method

The print heads are important components that discharge ink. They require periodic and appropriate maintenance. When problems such as dot drop-out are not resolved by medium cleaning, perform the more forceful "powerful cleaning" to remove clogging from the print heads.
IMPORTANT

Powerful cleaning consumes more ink than medium cleaning, and overly frequent use may damage the print heads themselves. Avoid performing this operation more than necessary.

MEMO If the media has already been set up, the After cleaning, perform a printing test. menu appears on the Powerful Cleaning screen. When this setting is turned on, a printing test is performed after cleaning.
Procedure
  1. Load the media.
    Setup of New Media
  2. Tap AP-640_Panel_Icon_MENU.
  3. Tap Cleaning - Powerful Cleaning.
  4. Tap Execute.
    Cleaning will start. On completion, you will return to the original screen.
  5. Tap AP-640_Panel_Icon_BACK.
  6. Tap Printing Test.
  7. Select Nozzle Drop-out Test and tap Execute.
    Perform a printing test again to check whether the dot drop-out and dot displacement have been corrected.
    MEMO

    • If the problem persists, try performing powerful cleaning again.

    • This cleaning can be effective when carried out periodically, according to the frequency of use.

    • If problems such as dot drop-out and dot displacement persist even after you have performed powerful cleaning several times, perform "manual cleaning."
