Abstract
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.
