Printer do's and don'ts for optimum print quality
Before you move or lift the printer, remove the toner cartridges, waste toner pack and fusing unit
to avoid spills. Be sure to keep the printer as level as possible. Damage caused by failure to remove
the supplies may void your warranty.
Do not touch the rollers of the fusing unit. This can degrade print quality.
