13. 2. Operation
쩸 While the copier is ready, the transfer belt stands by at a position separated from the photosensitive
drum.
쩹 When printing starts, the transfer belt is lifted and held in contact against the photoconductive drum.
쩺 Voltage from the high-voltage transformer unit is applied to the transfer belt via the power supply roller.
쩻 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.
쩼 After printing ends, the transfer belt is lowered and separated from the photoconductive drum to stand
by again.
