Notes on Head Cleaning
Ink is consumed during head cleaning.
Clean the print head only if print quality declines; for
example, if the printout is blurry or the color is
incorrect or missing.
When cleaning all nozzles, ink is consumed from all
colors.
Even if you are using only black inks for black and
white printing, color inks are also consumed.
Prepare a new maintenance box if there is not
enough empty space in the box.
If you repeat head cleaning several times in a short
period, the ink in the maintenance box may become
full soon as ink does not evaporate quickly from the
maintenance box.
Powerful Cleaning consumes much more ink than
Head Cleaning in the Maintenance menu.
Check the remaining ink level in advance, and prepare
a new ink cartridge before you start cleaning if the ink
is low.
