The device is fitted with two toner shutters (the toner refill shutter and the waste toner shutter) to prevent toner soiling from the toner refill inlet or the waste toner
outlet when a drum unit is being removed or replaced.
These shutters are not motor driven but are opened and closed manually.
The toner refill shutter is opened/ closed by means of the position of the manually operated lock slide on the drum unit. When the slide is in the lock position, the
toner refill shutter is open and when the slide is in the unlock position, the toner refill shutter is closed.
The waste toner shutter is opened/ closed by means locking and unlocking the manually operated lock lever on the process unit. When the lever is in the lock
position, the waste toner shutter is open and when the lever is in the unlock position, the toner refill shutter is closed.
