Service Call Procedures
Lubrication
The printer is lubricated during assembly at the factory and does not require periodic lubrica-
tion. Some parts require lubrication following replacement. These parts are identified in the
replacement procedures. When lubricating during replacement, use the grease approved for
all Phaser printers.
CAUTION
Plastic parts will deteriorate when unspecified grease and chemicals are used. To avoid dam-
age to the printer, use only Rheolube 768 grease.
• Rheolube 768 Grease: Part Number 070E00890
Cleaning Procedures
Purpose
The purpose is to provide cleaning procedures to be performed at every call.
Cleaning is indicated if the printer is having print-quality or paper-feeding problems. Some
cleaning procedures, such as purging the jet nozzles are done automatically when necessary.
Other procedures, such as scrubbing the Paper Feed Rollers with a moistened lint-free wipe,
must be done by the customers, but only if the Rollers are visibly dirty.
Cleaning is indicated by any of the following:
• Light stripes or missing colors appear in prints.
• Ink smears or random streaks appear on the front or back of prints.
• Only spots appear along the tops of prints.
• Mispicks or multiple picks occur at the media tray.
• Persistent paper jams inside the printer or at the media tray if the Rollers are visibly dirty.
• Wiggly vertical stripes caused by too much oil created by a dirty Drum Maintenance Unit
blade.
• Most print-quality problems can be corrected by running the cleaning procedures on the
printer’s Control Panel menu.
Procedure
CAUTION
Do not use any solvents unless directed to do so in this manual.
General Cleaning

otherwise in this manual. Wipe with a dry, lint-free cloth if a moistened cloth is used.
Inspect the vents on the exterior of the printer for dust. Clean as necessary.
Appropriate cleaning procedures, as listed in Table 1 and Table 2, should be performed when
