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.
