unused, and the displaced amount of remaining ink is not true.

3-3 Cleaning the Printing Heads
Switching on the sub power automatically performs maintenance operations, including cleaning of the printing head. This means that
there is normally no need to perform cleaning otherwise.
If drop-out occurs with printed images, clean the printing head.
* After cleaning, carry out a printing test. Load material.
The cleaning causes a certain amount of head wear and also consumes a certain amount of ink, so use should be kept
to a minimum.
[POWERFUL] results in faster head wear and also uses up much ink. (Performing cleaning from the [POWERFUL]
menu uses up about 57 cc of ink for six colors. This is because the process discharges all ink in the ink tube and
replaces it with fresh ink.)
