Product Technical Overview
Transfer and Detack
The toner image is transferred from the photoreceptor drum to the surface of the paper by the
bias transfer roll (BTR). The BTR is constructed of a metal shaft surrounded by a soft, conduc
-
tive urethane roll which has a positive charge. As the photoreceptor and BTR rotate together,
the positive charge of the BTR attracts the negative charge of the toner.
The paper is released from the photoreceptor drum by the detack saw and stripper fingers. A
voltage is applied to the detack saw to eliminate the charge on the paper. In cases where the
paper is still attracted to the photoreceptor drum, the stripper fingers will physically strip the
paper from it. Refer to Figure 15 and Figure 16.
NOTE: The detack saw is part of the transfer chute assembly, PL 90.15 Item 1.
