摘要： A guide system for xerographic printing apparatus introduces paper bearing an unfixed image and having a broad range of basis weights into a fuser nip from a prefuser transport without causing image smear. An entrance baffle is positioned in the path of the paper advancing toward the fuser nip for engagement by the paper's leading edge. The entrance baffle is hinged at its mounting end for swinging movement between a maximal and minimal positions as defined by stop members and is biased into engagement with the minimal stop member. The magnitude of the bias is chosen such that as the lightest basis weight paper engages the entrance baffle, it bends around its free end and is guided into the fuser nip, and such that as the heaviest paper engages the entrance baffle, it forces the entrance baffle toward engagement with the second stop member and itself is guided into the fuser nip.

摘要： An apparatus which transfers a developed image from a photoconductive member to a sheet. A sheet baffle guides an advancing sheet to the photoconductive member at the transfer station. The sheet baffle has an elongated axis extending in a transverse direction to the planer surface of the photoconductive member. A sensing unit, located prior to the transfer station, generates a signal indicative of the sheet basis weight. A regulator, responsive to the signal from the sensing unit, adjusts the position of the sheet baffle to position the elongated axis thereof at a selected angle relative to the planer surface of the photoconductive member. This angle is greater for a lightweight sheet than for a heavyweight sheet.

摘要： 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.
