13.3 General Description of Transfer Belt Unit Operation
1) The transfer belt unit is released from the photoconductive drum in the ready status.
2) The transfer belt is lifted, as well as rotated, and contacted with the photoconductive drum at the
start of printing.
3) The voltage of the high-voltage transformer is applied on the transfer belt through the power supply
roller.
4) Since the surface of the transfer belt is positively charged by a dielectric polarization, the belt elec-
trostatically attracts the paper from the drum. Thus the processes of transfer, separation and paper
transport are continuously performed.
5) The transfer belt unit is lowered, stops rotating, and waits at the released position from the photo-
conductive drum after the completion of printing.
