摘要： Electrostatographic recording method and apparatus that includes a primary image-forming member (PIFM) which moves along a closed path at high-speed. The PIFM may be in the form of an endless belt, which has a row of image frame synchronizing indicia. The indicia are spaced from each other in the direction of movement of the PIFM. The indicia are not all uniformly spaced from one another so that an interframe area larger than other smaller interframe areas on the PIFM can exist. During a production run toner images are formed on the image frames by sensing the image frame synchronizing indicia. The larger interframe area is provided preferably at a splice or seam area to provide sufficient time for a change in a process element for which sufficient time is not available at a smaller interframe area. As an example, the process element may be a transfer roller which is switched in polarity at the larger interframe area to reduce toner contamination of the transfer roller due to presence of the seam or placement of toner at process control patches at such area. The endless belt may contain a single row of indicia that are used to synchronize two respective different series of image frame sizes.

摘要： An electrostatographic recording apparatus and method wherein a primary image forming member (PIFM) is moved along a closed path. The PIFM is sufficiently large to form a series of images thereon in the direction of movement of the PIFM during a production run. Plural series of toner images are formed on the PIFM during production runs. The toner images are transferred from the PIFM by engaging the PIFM with a transfer device. A cycle-down of the apparatus is provided to stop movement of the PIFM so that the PIFM is stopped to park the transfer device in a predetermined location on the PIFM preferably a seam area of the PIFM.

摘要： An electrometer probe is used in an electrophotographic apparatus as part of a process control system to measure charge on a photoconductive film belt. This measurement is used to control voltage level or other process parameter of the electrophotographic process. The probe is supported in an electrometer probe holder so that a sensor aperture of the probe is at a fixed distance from the film belt. In order to ensure proper operation of the electrometer probe, a method and an apparatus for independently calibrating the electrometer probe is provided. A curved plate is provided on the electrometer probe holder. The plate is mounted at the same spacing from the probe aperture as the film belt. This plate has a receptacle for the service person's test lead to attach. The other end of the test lead is attached to a test point for the toning station bias supply. The probe may be reoriented on the probe holder to position the probe aperture at the fixed distance to the plate. Using a service test program, different biases are applied to the plate, and the response of the electrometer is monitored. In this way, troubleshooting of electrometer related errors is easily done without the need to remove the electrometer probe to a special test apparatus.

摘要： A dry electrophotographic printer is operated to remove toner from a longitudinal member. A process-control time interval, and a cleaning time interval that is a positive multiple thereof, are selected. Prints are produced until the process-control time interval elapses, as measured by a timing device. A process-control patch is produced in a process-control frame. This is repeated until the cleaning interval has elapsed. In the process-control frame, after the cleaning interval elapses, the photoreceptor and development member are spaced apart, then, after a selected time delay, brought into operational relationship, so that a stop at one end of the photoreceptor contacts an end block at one end of the development member, and toner is removed from the longitudinal member, which is connected to the end block.

摘要： Apparatus for removing toner after a selected time interval from a longitudinal member in a dry electrophotographic printer for printing a visible image on a receiver. An end block is disposed at one end of a rotatable development member, and a longitudinal member is disposed adjacent to the development member or photoreceptor and is connected to the end block. A backup bar is disposed adjacent to the photoreceptor and can selectively make physical contact with at least one point on the end block. When a measured time interval of printer operation reaches the selected time interval, a controller causes the backup bar to apply a selected force to the end block to cause toner on the longitudinal member to be removed from the member.
