摘要： An apparatus is provided for reducing transfer deletions in an electrostatographic machine. The apparatus includes a registration controller for driving a print substrate at a registration velocity and feeding the print substrate to an image-retentive member. The apparatus also includes a system controller operably associated with the registration mechanism controller. The system controller monitors at least one operating parameter of an image forming apparatus and generates a control signal in response to the monitored operating parameter(s). The registration controller is responsive to the control signal and is configured to adjust the registration velocity in accordance with the control signal as the image-retentive member is driven at a preselected velocity. The apparatus further includes a transfer assist mechanism movably mounted adjacent a photoreceptive member so the transfer assist mechanism may be moved from a non-operative position to an operative position to provide substantially uniform contact between the print substrate and the image-retentive member.

摘要： An apparatus for assisting in the transfer of an image from an image bearing member onto a copy substrate, comprises an image bearing member carrying an image to be transferred, a feed mechanism for feeding a copy substrate to the image bearing member, and a transfer assist mechanism movable to an activated position bearing on the substrate to maintain the substrate in contact with the image bearing member to assist in transferring the image thereto, and to a de-activated position. A sensor generates a signal in response to passage of the leading edge and the trailing edge of the substrate to ascertain an actual length of the substrate as it moves to the image bearing member. A controller is operable to direct the transfer assist mechanism to move to the activated position and then to direct the transfer assist mechanism to move to the de-activated position after a de-activation dwell time. The de-activation dwell time is at least initially a nominal dwell time based on an expected length of the substrate from its leading edge to its trailing edge. The controller is operable to change the de-activation dwell time from the nominal dwell time in response to the determination of the actual length of the substrate.
