• The 4in1 Type has an operation panel (6) in front with a full array of buttons, a 10-key panel, and
a 7-digit display. The top of the machine is covered by an ADF (7) that can hold and feed 15
originals, and a flatbed scanner unit (8).
Common AIO
The AIO (All-In-One) cartridge (or print cartridge) in the center of the machine is permanently sealed
around the main elements of the printing mechanisms: (1) drum charge unit, (2) drum, (3) development
unit, (4) tone supply unit, (5) cleaning blade, and (6) waste toner collection tank.
• Throughout the service manual this unit is called the "AIO" (All-In-One).
• The AIO is common to all machines of this series.
• There are no serviceable parts inside the AIO. (Disassembly of an AIO is never required.)
• When the AIO runs out of toner, the toner waste tank can be emptied and the toner supply tank
can be refilled with fresh developer/toner.
• An AIO can be refilled up to three times (this is the approximate service life of the drum). The
refillings greatly extend the service life of the AIO.
• The AIO can be easily removed and replaced by the user.
