open the toner door to access the toner cartridge, clear jams,
and clean the printer. To open the toner door, firmly grasp the left
and right sides and pull the toner door toward you.
Note You will feel some resistance when opening the toner door. Opening
the toner door conveniently lifts the toner cartridge for easy removal.
