Print Head Deep Cleaning
If print quality does not improve by standard print head cleaning, try print
head deep cleaning, which is a more powerful process. Print head deep
cleaning consumes ink, so perform this procedure only when necessary.
1
Prepare settings.
Connect TV to the printer and turn them on.
See “Connect TV to the printer.” on page 13.
2
Start Print Head Deep Cleaning.
(1) Use the buttons to select Tool Box from the menu screen and then press
the button.
(2) Use the
button to select Deep Cleaning
and then press the button.
(3) Use the
buttons to select Yes and then
press the button.
Important
Do not perform any other operations until the print
head deep cleaning finishes. This takes about one
minute.
When print head deep cleaning finishes, the confirmation message is displayed.
Select Yes.
note
After print head deep cleaning finishes, print the nozzle check pattern to verify
that the print head nozzles are clean.
See “Printing the Nozzle Check Pattern” on page 56.
If the problem remains, replace the ink tank.
See “Replacing an Ink Tank” on page 60.
If ink tank replacement does not resolve the problem, the print head may be worn
out. Contact a Canon service representative.
