Cleaning the print head
If you find that your printed image is unexpectedly faint or dots in the printed
image are missing, you may be able to solve the problem by using the Head
Cleaning utility to clean the print head, which ensures that the nozzles are
delivering ink properly.
Note:
❏Do not start the Head Cleaning utility whi le printing is in progress; otherwise, you r
printout may be marred.
❏To save ink, use the Nozzle Check utility first to confirm that the print head needs
to be cleaned.
❏When the ink status light is flashing or on, you cannot clean the print head.
Replace the appropriate ink cartridge first. See "Replacing Ink Cartridges" on
page 169.
