Toner collecting port shutter mechanism

• The toner collecting port is equipped with a shutter mechanism that prevents toner from
being spilled out when the toner cartridge is removed from the main body.
• After installing the toner cartridge into the main body, placing the print unit release lever
in its locked position opens the shutter of the toner collecting port. Then toner can be
conveyed to the main body.
• Moving the print unit release lever to the right or left accompanies the synchronizing
movement of the slider. This makes the gear connected to the shutter rotated and then
makes the shutter opened or closed.
• To prevent the front door from getting closed while the shutter is open, the preventive
mechanism works in the way that the front door cannot be closed by interfering with the
release lever until the release lever is placed in the locked position (to the left in the pic-
ture).
