contacts
If you use the printer in a dusty environment, debris may
accumulate on the copper-colored contacts and cause
printing problems.
To clean the print cartridge contacts
1. Gather the following items to clean the contacts:
– Distilled water (tap water may contain
contaminants that can damage the print
cartridge)
– Cotton swabs or other soft, lint-free material that
will not stick to the print cartridge
2. Open the print cartridge door.
3. Remove the print cartridge and place it on a piece of
paper with the ink nozzle plate facing up. Be careful
not to touch the copper-colored contacts or the ink
nozzle plate with your fingers.
Caution Do not leave the print cartridge
outside the printer for more than 30 minutes.
Ink nozzles exposed to the air longer than
this may dry out and cause printing
problems.
4. Lightly moisten a cotton swab with distilled water
and squeeze any excess water from the swab.
5. Gently wipe the copper-colored contacts with the
cotton swab.
Caution Do not touch the ink nozzle plate.
Touching the ink nozzle plate will result in
clogs, ink failure, and bad electrical
connections.
