To ensure the best print quality and the most reliable printer operation, follow these simple guidelines:

• Use high-quality paper and only Xerox transparencies and glossy coated paper.
• Do not use any media designed for inkjet printers, especially inkjet coated paper and inkjet transparencies. Inkjet media are coated with a substance that may damage the Fuser; Xerox does not furnish service for damage or malfunction caused by the use of non-Xerox supplies or consumables. Xerox coated paper and transparencies have been specially designed for use with Xerox Color Laser Printers.
• Double-sided printing and specialty media will require more frequent cleaning of the rollers and will reduce the average life of the consumables.
• Auto-duplex only with laser bond paper that is 75 - 90 g/m2 (20 - 24 lb.). Do not use paper that is lighter than 75 g/m2 (20 lb.); it is not opaque enough for acceptable duplex prints.
• Use only laser paper for automatic double-sided printing with the Duplex Unit.
• Keep the Imaging Unit's light exposure to a minimum -- less than 90 seconds of artificial light and no exposure to sunlight -- or you may damage the unit:
• When installing a new Imaging Unit, keep the protective plastic sheet on until immediately before inserting the unit.
• If, when installing the Imaging Unit, you also need to install other components, install the Imaging Unit last to minimize its light exposure.
• When changing a Toner Cartridge or clearing a media jam, make sure that you close the printer's right side door quickly to avoid any light exposure to the Imaging Unit.
• Do not leave the printer's front door open for extended periods of time (for example, several hours).
• Do not touch the underside or the right side of the Imaging Unit; fingerprints may appear on your output.
• If your printer is a Phaser 740L printer (check the nameplate above the front panel display), make sure that you keep the light shield in place to protect the Imaging Unit. Only remove the light shield when adding color to your printer.
