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 improperly 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.
