Cleaning the print head

If you find that the printed data is unexpectedly faint or dots in the printed data are missing,
you may be able to solve these problems by using the Head Cleaning utility to clean the
print head, which ensures that the nozzles are delivering ink properly.
To use the Head Cleaning utility, follow the steps below.
Note:
❏ Do not start the Head Cleaning utility while printing is in progress; otherwise, your printout may
be marred.
❏ To save ink, use the Nozzle Check utility first to confirm that the print head needs to be cleaned.
This is because the cleaning process consumes some ink.
❏ 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 133.
1. Make sure the printer is turned on and the ink status light is off.
2. Click Head Cleaning.
3. Follow the on-screen instructions.
4. Click Confirmation in the Head Cleaning dialog to confirm that the head is cleaned and
to reset the cleaning cycle.
If you still find missing dots after cleaning, try these solutions.
❏ Select POWER CLEANING from the control panel on the printer. See "POWER
CLEANING" on page 107.
❏ Repeat this procedure four or five times, turn the printer off and leave it alone overnight,
and then try head cleaning again.
❏ Replace some of ink cartridges as they may be old or damaged.
If the print quality remains a problem after you have tried these solutions, contact your
dealer. See "Contacting Customer Support" on page 174.
