Maintenance
4. When the
P
power light stops flashing, click the
Confirmation
button in the Head Cleaning dialog box to
print a nozzle check pattern and to reset the cleaning cycle.
Use the check pattern to confirm that the head is clean. Refer
to page 148 to see a sample of the nozzle check pattern.
If print quality has not improved after repeating this procedure
four or five times, turn the printer off and leave it alone overnight.
Then do the nozzle check again, and repeat the head cleaning if
necessary.
If the print quality still has not improved, some of your ink
cartridges may be old or damaged and may need to be replaced.
To replace an ink cartridge, see “Replacing an Ink Cartridge” on
page 279.
If print quality remains a problem after replacing the ink
cartridges, contact your dealer.
Note:
To maintain print quality, we recommend printing a few pages at least
once every month.
