Cleaning Ink Jets 5-3
Cleaning Ink Jets Maintenance interval: daily.
Before running AutoSet, which compensates for missing and
misfiring ink jets, you should clean the jets as described in the
following paragraphs to help keep them clear of accumulated
ink.
The effectiveness of the high-resolution printing process used
by the printer can be impaired by printheads that are improp-
erly maintained. Partially clogged nozzles may cause the jets to
misfire intermittently, or deflect ink slightly in the wrong direc-
tion.
Cleaning the ink jets daily should be sufficient in most cases.
Cleaning will likely be required more often if the printer sits idle
for extended periods.
1. From the Front Page screen of the control panel, press the
Carriage key.
The carriage moves out from the service station and stops.
2. Open the printer’s top cover.
3. Depress the lock levers to unlock the printhead assembly, and
swing up the carriage to expose the ink jets.
4. Gently wick the ink jet nozzles with a nonfibrous, lint-free
swab moistened with water. DO NOT USE ALCOHOL, use
plain water.
If you find excessive buildup on the bottom of the print-
head, clean off the excess using a moistened pad, and then
wipe the bottom of the printhead with the swab.
Caution
Do not to touch the contacts or orifice plate (jet noz-
zles) with your bare fingers. Also, take care not to
use excessive force when wiping the printheads with
the swabs or pads.
5. Close the printer’s top cover.
6. Swing the printhead assembly down into the printing posi-
tion, and push the printhead assembly down into position
until it engages the lock levers with a click.
