13. 2. Operation
While the copier is ready, the transfer belt stands by at a position separated from the photosensitive
drum.
When printing starts, the transfer belt is lifted and held in contact against the photoconductive drum.
Voltage from the high-voltage transformer unit is applied to the transfer belt via the power supply roller.
As the surface of the transfer belt is electrified by a plus voltage by dielectric polarization, the paper is
held in contact by static electricity, and the processes of transfer, separation, and paper transport can
be carried out continuously.
After printing ends, the transfer belt is lowered and separated from the photoconductive drum to stand
by again.
