Wiping the Print Cartridge Nozzles and Contacts
If print quality does not improve after repeating the nozzle test, the
problem may be caused by dried ink on the:
¥ Print cartridge nozzles.
¥ Print cartridge contacts.
¥ Print cartridge carrier contacts in the printer.
1. Remove the print cartridge. See ÒReplacing the Print CartridgeÓ
on page 3.18.
2. Use a clean cloth, dampened with water only, to gently clean the entire
copper coloured area, including the nozzles and contacts. To dissolve
any dried ink, hold the damp cloth against the nozzles for about three
seconds. Gently blot and wipe dry.
