Cleaning Ink Jets 3-11
Cleaning Ink Jets
In addition to running AutoSet, which compensates for missing
and misfiring ink jets, you should clean the jets as described in
the following paragraphs to keep them clear of accumulated ink.
The effectiveness of the high-resolution printing process used
by the printer can be impaired by cartridges that are improperly
maintained. Partially clogged nozzles may cause the jets to mis-
fire intermittently, or deflect ink slightly in the wrong direction.
Cleaning will likely be required more often if the printer sits idle
for extended periods.

4. Open the printer’s top cover.
5. On one of the ink tubes, close the valve near the Big Ink pack.
Failing to do this can cause ink to flow backwards into the
Big Ink supply, which may keep the cartridge from refilling.
6. Release the ink jet cartridge from the print head carriage.
7. Gently wick the ink jet nozzles and wipe the electrical con-
tacts with a nonfibrous, lint-free foam swab moistened with
water. DO NOT USE ALCOHOL, use plain water.
If you find excessive buildup on the bottom of the cartridge,
clean off the excess using a moistened pad, and then wipe
the bottom of the cartridge with the swab.
8. Replace the ink jet cartridge into the print head carriage.
9. Repeat this process for each cartridge.
Caution
When handling cartridges, do not to touch the con-
tacts or orifice plate (jet nozzles) with your bare fin-
gers. Also, take care not to use excessive force when
wiping the cartridges with the swabs or pads.
