ABSTRACT:
A transfer system including a contact member for applying pressure against a copy substrate to create uniform contact between the copy substrate and a developed image on an imaging member. The transfer system includes a flexible transfer assist blade and a rotatable cam shaft having a lobe for deflecting the transfer assist blade into contact with the copy substrate. Alternatively, the transfer assist blade may include multiple segments and the rotatable cam shaft may include a plurality of lobes, each having a lengthwise dimension corresponding to predetermined segments of the blade for providing contact across a dimension corresponding to that of the copy substrate. The system further includes a stepper motor for rotating the cam to predetermined angular positions to create an abutting relationship between the lobe and the transfer assit blade for deflecting selected segments of the blade toward the copy substrate. The transfer assist blade presses the copy sheet into contact with at least the developed image on the photoconductive surface to substantially eliminate any spaces or gaps between the copy sheet and the developed image during transfer of the developed image from the photoconductive surface to the copy sheet.
