Waste Tray Lubrication Inspection Cleaning and Maintenance A Control Panel message indicates when the maintenance kit is low. Printing is still possible when the Drum Maintenance Kit is low. When the message indicates the Drum Maintenance Kit is "empty," replace the kit to continue printing. Note The Drum Maintenance Kit fluid, an oil, poses no known adverse health effects. See the Material Safety Data Sheet at www.xerox.com/office/ msds. 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. 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). 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.)
