Remarks
Set a sheet of plain paper (A4 or Letter) in the cassette, or the
rear tray if selected.
Unclogging of the print head nozzles, and maintenance to
keep the print head conditions good.
If there is a missing portion or white streaks in the nozzle
check pattern printout, perform this cleaning.
If print head manual cleaning is not effective, perform this
cleaning. Since the deep cleaning consumes more ink than
regular cleaning, it is recommended to perform deep cleaning
only when necessary.
Set a sheet of plain paper (A4 or Letter) in the cassette, or the
rear tray if selected. Then, scan the printed pattern. If the
automatic print head alignment is not effective, perform
manual print head alignment.
Set 3 sheets of plain paper (A4 or Letter) in the cassette, or
the rear tray if selected.
Confirmation of the current print head alignment values.
The paper feed rollers of the selected paper source (the rear
tray or the cassette) rotate while being pushed to the paper
lifting plate. Since the rollers will wear out in this cleaning, it
is recommended that you perform this only when necessary.
Cleaning of the platen ribs when the back side of paper gets
smeared.
Fold a sheet of plain paper (A4 or Letter) in half crosswise,
then unfold and set it in the rear tray with the folded ridge
facing down. (No paper feeding from the cassette)
