Xerox Disclosure Journal
The subject disclosure relates to apparatus for effecting transfer of toner images from a photoreceptor drum 10 to a copy sheet 12 comprising plain paper. To this end, a transfer corona device 14 supported by an arm 16 is rotatably supported internally of a transfer drum 17 such that it can be moved by, for example, a spring drive mechanism (not shown) to its operative position depicted in Figure 1. The transfer corona is held stationary in that position by means of a pin 18 carried thereby and pin release mechanism 19 (Figure 2). The transfer corona is held in the position shown until the transfer drum 17 to which the copy sheet is secured by a gripper mechanism generally indicated at 20 has moved the sheet entirely through the nip area 22 between the photoreceptor and the drum to effect transfer of the powder images contained on the drum. After transfer the pin release mechanism is actuated to allow the armrith the transfer corona to be rotated to its inoperative position approximately 180 from the position shown in Figure 1.
