Phaser 840 and 850 Color Printers
Maintenance
Maintenance roller
The printer uses the maintenance roller as part of its self-maintenance routine to
coat the print drum with oil before each print. The Phaser 840 maintenance roller
(and its counter) must be replaced after about 30,000 prints (the starter
maintenance roller must be replaced after 10,000 prints). The maintenance
cartridge of a Phaser 850 printer lasts between 23,000 to 45,000 prints depending
on the ink coverage (higher ink coverage lowers the life of the cartridge.); refer to
the printer’s Usage Report.
A front panel message indicates when the maintenance roller is low. Printing is
still possible when the maintenance roller fluid is low. When a front panel
message indicates that the maintenance roller is “empty,” the maintenance roller
and its counter must be replaced before continued printing is possible. Refer to
the instructions included with the kit to replace the maintenance roller kit.
Phaser 840 and Phaser 850 maintenance cartridges are interchangeable.
Note
The drum fluid, an oil, poses no known adverse health effects.
Refer to the Material Safety Data Sheet for amino oil in
printer’s
Advanced Features and Troubleshooting Manual
for more
information.
Waste tray
The maintenance drawer contains a waste tray that collects ink that has been
purged from the printer’s ink jets. The waste tray should be emptied each time
the maintenance drawer is removed from the printer. Refer to the printer’s user
guide for instructions on removing and emptying the waste tray. Be sure to insert
the waste tray into the maintenance drawer before reinstalling the maintenance
drawer in the printer. Never reuse waste ink in the printer.
