Medium 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 normal cleaning, perform the more forceful "medium cleaning" to remove clogging from the print heads.
IMPORTANT

Medium cleaning consumes more ink than normal 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 Medium 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 - Medium 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 medium cleaning again.
    • If problems such as dot drop-out and dot displacement persist even after you have performed medium cleaning several times, perform "powerful cleaning."
    • This cleaning can be effective when carried out periodically, according to the frequency of use.
