Cleaning the Print Head
The bottom of the ink jet cartridge is covered with wet ink.
Avoid contact of ink with skin and clothing. Ink may cause irritation -
especially to the eyes.
3.1.
Cleaning the Print Head Automatically
If the ink on the page looks splotchy or smeared, or if blank spaces appear in
characters, the print head should be cleaned. To automatically clean the print head,
press CODE + SHIFT + INK CHG.
3.2.
Cleaning the Ink Jet Nozzles and Contacts
If print quality does not improve after automatically cleaning the print head, the problem
may be dried ink on the nozzles, contacts, or on the print cartridge bracket contacts.
(1) Remove the ink-jet cartridge.
(2) With a clean, water-dampened cloth, gently wipe the entire copper colored area,
including the nozzles and contacts.
NOTE:
•
To dissolve any dried ink, hold the damp cloth against the nozzles for a few seconds;
then gently blot and wipe dry.
(3) Allow the copper-colored area to dry, and re-install the cartridge.
(4) Press RETURN, and then CODE + SHIFT + INK CHG, and close the cover.
NOTE:
•
If the machine still fails to print properly, clean the bracket contacts in the carriage.
