    摘要： An electrostatographic printing apparatus comprises a charge receptor, and a transfer station for transferring a toner image from the charge receptor to a sheet. The sheet passes through a nip formed between the charge receptor and a moving transfer belt. Upstream of the nip, the belt forms a shallow angle relative to the charge receptor; downstream of the nip, the belt forms a steep angle relative to the charge receptor. This configuration enables self-stripping of the sheet from the transfer belt at the exit of the nip.

    摘要： An apparatus and method for automatically adjusting the timing of a transfer assist blade in an electrostatographic imaging system. The apparatus and method operate by partially toning an area of the photoreceptor and then actuating the transfer assist blade such that it smears at least a portion of the partially toned area. Using an electronic toner area cover sensor system, the amount of smearing can be determined, From this, the timing of engagement of the transfer assist blade with the photoreceptor can be determined and, if necessary, adjusted.

    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.

    摘要： In a printing machine having at least one transfer device driven in response to an electrical signal and operable to transfer a medium onto a sheet, a method of controlling the magnitude of the electrical signal driving the transfer device comprises assigning a magnitude of the electrical signal for driving the transfer device to each of at least two transfer stress conditions, evaluating at least one operating parameter of the printing machine relative to a corresponding pre-determined threshold value, selecting one of the at least two transfer stress conditions based on the evaluation of the at least one operating parameter, and applying the magnitude of the electrical signal corresponding to the selected stress condition to the electrically-driven transfer device. The operating parameters may include environmental parameters, such as altitude and humidity, sheet properties, such as paper weight, and machine parameters, such as transfer device life.

    摘要： An apparatus is provided for reducing transfer deletions in an electrostatographic machine. The apparatus comprises a registration mechanism controller for driving a registration mechanism in the process direction. 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 mechanism controller is responsive to the control signal and drives the registration mechanism at a velocity that corresponds to the control signal. 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 a print substrate supplied from said registration mechanism and said photoreceptive member.

    摘要： An improved coronode assembly includes pin guards that are positioned closely spaced from and extending above a coronode in order to provide protection for a user reaching past the coronode to remove a sheet jam, and prevent coronode damage when the coronode is handled during servicing by a field service technician. The closeness of the pin guards to the coronode also serves to produce a more uniform field.
