The transfer roller [A] is always pressed against the image transfer belt by pressure from a spring. The
transfer roller moves toner images [B] from the transfer belt to the paper. When a sheet of paper [C]
goes between the transfer roller and the transfer belt, the transfer roller turns with the paper.
The transfer unit has a discharge plate [D] above the transfer roller. The discharge plate removes
charge that was applied to the paper during paper transfer. This helps paper move away from the
transfer roller.
Waste Toner Bottle
The waste toner collection coil [A] moves collected waste toner from the ITB (image transfer belt) unit to
the entrance [B] of the waste toner bottle. The agitator plate [C] levels the collected waste toner in the
waste toner bottle. It is driven by the waste toner collection motor [D].
The waste toner bottle set sensor [E] detects whether the waste toner bottle is set. If it is not set,
"Waste Toner Bottle" appears on the LCD on the machine.
The waste toner overflow sensor [F] detects whether the waste toner bottle is full. If it is full, "Replace
the Waste Toner Bottle" appears on the LCD on the machine. 400 more pages can be printed, then the
machine stops.
