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 and dot displacement 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.
