Quality Check Sheet, and then check it.

Press Stop/Exit.
If you still see missing ink in this Print Quality Check Sheet, repeat the cleaning
and test print procedures at least five times. If ink is still missing after the fifth
cleaning and test print, replace the ink cartridge for the clogged color. (Perhaps
the ink cartridge was in your fax machine over six months or the expiration date
written on the cartridge package has passed. Or, the ink may not have been
stored properly before use.)
After replacing the ink cartridge, check it by printing another Print Quality
Check Sheet. If the problem still exists, repeat the cleaning and test print
procedures at least five times for the new ink cartridge. If ink is still missing,
call Customer Service at 1-800-284-4329 (
in USA ), 1-800-853-6660 ( in
Canada ) or 1-514-685-6464 ( in Montreal ).
Caution
Do NOT touch the print head. Touching the print head may cause permanent
damage and may void the print head’s warranty.
When an ink head nozzle is clogged
the printed sample looks like this. After the ink head nozzle is cleaned,
the horizontal lines are gone.
