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

service parts for the AIO.
• The AIO can be easily removed and replaced by the user. For more details, please refer to the
