If Drop-out Persists Even After Carrying Out Cleaning Several Times

Perform head cleaning only when there is dot drop-out (gaps) or printing becomes faint.
Performing head cleaning more than necessary subjects the heads to wear and consumes ink. In particular, cleaning performed
at the [POWERFUL] menu for [HEAD CLEANING] can cause premature head wear and consume large amounts of ink.
(Performing cleaning at the [POWERFUL] consumes approximately 70 cc (when you are using SJ-740), or approximately 65 cc
(when you are using SJ-640), or approximately 60 cc (when you are using SJ-540) of ink for each group.)
