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 is more forceful cleaning that consumes more ink than Normal Cleaning.

MEMO

If the object to be printed on is set up before Medium Cleaning is performed, After cleaning, perform a printing test. will be displayed on the Medium Cleaning menu screen. When this setting is turned on, Printing Test will be performed after Medium Cleaning even if Nozzle Drop-out Test is not performed.

    • If problems such as dot drop-out and dot displacement persist even after you have performed Medium Cleaning several times, perform Powerful Cleaning.
