AIO (All In One) Cartridge
The AIO (print cartridge) in the center of the machine is permanently sealed around these main elements
of the printing mechanisms: 1) OPC drum, 2) charge unit, 3) development unit, 4) drum cleaning unit,
and 5) toner supply unit.
• This print cartridge is called the "AIO" (All-In-One) throughout this service manual.
• When toner runs out, the AIO can be refilled by the service technician or the AIO can be replaced
by the operator. Refilling requires removal of two caps: the square cap to dump the toner and the
round cap for refilling. These two parts are the only service parts for the AIO. There are no other
service parts for the AIO.
• The AIO can be easily removed and replaced by the user. For more details, please refer to the
operating instructions.
