To maintain print quality, use the troubleshooting information in this book and the Quick Reference Guide, as well as the Consumables Page and Service Print 1 in the front panel's Help Pages menu.
Double-sided printing and specialty media will require more frequent cleaning of the rollers and will reduce the average life of the consumables.
Caution: 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:
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.
Use only laser paper for double-sided printing; other media may damage printer components.
