5.0 MAINTENANCE
5.1 LUBRICATION AND CLEANING
5.1.1 Lubrication
There are no lubrication points in the printer. All parts are either permanently lubricated or are
designed to operate dry. No lubricants should be used. They may adversely affect operation.
5.1.2 Document Feed Roller Cleaning
1. Open the cabinet.
2. Moisten a lint-free cloth with isopropyl alcohol and wipe the front rollers while rotating the
gear on the end of the roller shaft. Do not use any strong solvents in place of alcohol.
3. In similar fashion, clean the rear rollers. Make sure all rollers are dry and free of residue.
5.1.3 Sensor Cleaning
Clear sensor light paths of paper, paper dust and other obstructions if rollers continue to run
when no document is present or other sensor problems occur.
1. Insert the flexible nozzle tube of a compressed air can under the input guide and near each
of the document sensors. Clear each sensor area with a 5-second burst of air.
