Transfer/Separation And Conveying Sections - Kyocera Mita KM-4530 Service Manual

2-1-5 Transfer/separation and conveying sections

The transfer/separation section consists of the transfer charger unit and the drum separation claw. The transfer charger
unit consists of the transfer charger for transferring the toner image on the drum onto paper and the separation charger
for separating the paper from the drum. The transfer charger performs transfer charging by applying a high voltage
generated by the high voltage transformer PCB (HVTPCB) to both ends of the tungsten wire. The separation charger,
when an alternating voltage is applied from the high voltage transformer PCB (HVTPCB), discharges it and neutralizes
the residual charge on the paper for which transfer is complete. The paper is therefore separated from the drum by its
own weight. The drum separation claw is used as auxiliary measures for separating securely the paper that has been
separated from the drum.
The paper conveying section consists of the paper conveying belt assembly, the paper conveying motor (PCM), and so
on. The paper that passes through the transfer/separation section is conveyed to the fixing section with the paper
conveying belt. Holes are provided on the paper conveying belt and the paper conveying fan motor (PCFM) attracts the
paper from under the paper conveying section.
