Figure 1-3-33 Transfer and separation section
The transfer and separation section consists of the transfer charger assembly and drum
separation claws.
The transfer charger assembly consists of the transfer charger that applies a high
voltage to transfer the toner image from the drum surface onto the paper, and the
separation charger that helps the paper separate from the drum surface.
In the transfer charger, a high voltage generated by the high-voltage transformer PCB
(HVTPCB) is applied to the both ends of the tungsten wire.
The separation charger uses the AC voltage applied from the high-voltage transformer
PCB to neutralize the residual charge on the paper after the transfer process. The paper
can then separate from the drum under its own weight.
The separation claws ensure that the paper separates reliably from the drum.
