Shutter Mechanism
When the toner bottle holder is opened, a self-sealing shutter prevents toner spill.
The top of the shutter [A] has a semi-circular opening [B]. Normally, toner from the toner bottle [C] flows
through this opening into the hopper below.
However, pulling out the shutter cover [D] closes the cover automatically to prevent toner spill from the
hopper.
