Waste Tray
The Waste Tray collects ink that has been purged from the ink jets. A Control
Panel message indicates when the Waste Tray is full. Empty the waste tray to
continue printing.
Caution
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 all Phaser printers. The
grease part number is 070E00890.
Caution
Plastic parts will deteriorate when unspecified grease and chemicals are
used. To avoid damage, use only Rheolube 768 grease (P/N 070E00890).
Inspection
Replace the rollers when you see any of the following defects:
■ Flat spots
■ Out of roundness
■ Cracked rubber
■ Loss of traction (tackiness) causing pick or feed failures
Replace gears that show any signs of wear or damage. Look for these
problems:
■ Thinned gear teeth
■ Bent or missing gear teeth; check especially where a metal gear drives a
plastic gear.
■ Fractured or cracked gears (Oil or incorrect grease on a plastic gear can
cause the gear to crack.)
