Cleaning the Print Head
If you find that the nozzle check result is
unexpectedly faint or some dots in the printed image
are missing, you may be able to solve these problems
by cleaning the print head, which ensures that the
nozzles are delivering ink properly.
Note:
❏ Print head cleaning uses both color and black ink. To
avoid wasting ink, clean the print head only if the copy
quality drops (for example, blurred printout,
incorrect or missing color).
❏ Before cleaning the print head, perform the nozzle
check first to see if it really needs to be cleaned. This
saves ink.
❏ When a message appears on the LCD panel to prompt
you to replace the ink cartridge or to indicate the ink
is low, you cannot clean the print head. In this case,
replace the appropriate ink cartridge first.
Press the Setup button.
