Toner collecting port shutter mechanism

• A shutter mechanism is provided to prevent waste toner from being spilled from the toner
collecting port when the waste toner box is removed and reinstalled.
• Placing the shutter lever in the "locked" position (to the front side of the main body)
closes the shutter of the toner collecting port.
• The transfer belt unit can be removed after removing the waste toner box, closing the
shutter of the toner collecting port, and removing the fixing screws.
• A preventive mechanism works to stop the transfer belt unit from being removed with the
toner collecting port opened. Due to the shutter lever interfering with the suction trans-
port unit, the transfer belt unit cannot be removed until the shutter lever is placed in the
locked position. Similarly, to install the transfer belt unit, the shutter lever needs to be
placed in the locked position so that the shutter lever will not interfere with the suction
transport unit.
• To prevent the toner collecting port shutter from leaving unopened after the installation of
the transfer belt unit, installing the waste toner box pushes the shutter lever of the toner
collecting port and opens the collecting port.
