Lubrication; Inspection - Xerox Phaser 8400 Service Manual

A front panel message indicates when the Maintenance Kit is low. Printing is still
possible when the Maintenance Kit is low. When a front panel message indicates that
the Maintenance Kit is "empty," the Maintenance Kit must be replaced before
continued printing is possible. Refer to the installation instructions included with the
Maintenance Kit.
Note
The maintenance kit fluid, an oil, poses no known adverse health effects. See the
Material Safety Data Sheet at www.xerox.com/office/msds.
Waste Tray
The waste tray collects ink that has been purged from the printer's ink jets. A front
panel message indicates when the waste tray is full. Refer to the printer's Reference
Guide for instructions on removing and emptying the waste tray. A front panel
message displays when the waste tray needs to be emptied (usually after seven
purges). Never reuse waste ink in the printer; it will damage the printhead.

Lubrication

The printer is lubricated during assembly at the factory and requires no periodic
lubrication. Some parts require lubrication following replacement. These parts are
identified in the replacement procedures. When lubricating during replacement, use
the grease approved for the Phaser 8400 Printer. The grease part number is 006-7997-
00).
Caution
It is essential to use only the approved grease. Some lubricants will damage
plastic components, including the printer chassis.
