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.

Process control with longitudinal member toner removal

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.

Removing toner from longitudinal member in printer

Toner is removed, after a selected time interval, from a skive mount in a dry electrophotographic printer. An end block is disposed at one end of the rotatable development member, and a skive mount disposed adjacent to the development member connects a skive to the end block. A timing device measures a time interval of printer operation. At the selected time interval, a controller causes a backup bar to lift away from the photoreceptor, then, after a selected time delay, causes the backup bar to make physical contact with at least one point on the end block, so that the backup bar applies a selected force to the end block to cause toner on the skive mount to be removed.

Removing toner from skive mount in printer

Toner is removed from a skive mount in a dry electrophotographic printer. An end block is disposed at one end of the rotatable development member, and a skive mount disposed adjacent to the development member connects a skive to the end block. A timing device measures time intervals of printer operation. A process-control time interval and a cleaning time interval that is a non-negative multiple of the process-control time interval are selected. Prints are made until the process-control time interval elapses. A process-control patch is produced in a process-control frame. Once the cleaning interval has elapsed, in the process-control frame, a backup bar is lifted lift away from the photoreceptor, then, after a selected time delay, brought into physical contact with at least one point on the end block, so that toner is removed from the skive mount.

Removing toner during printer process-control frame

A method and apparatus for assembling copy sets of a first or principal copy job including a plural number of identical copies of an original document of one or more pages with a supplemental copy job including a like plural number of copy sheets. The first copy job is reproduced in either a first mode wherein the copies are made of the original document last page first to first page last copy order or a second mode wherein copies are made of the original document first page first to last page last copy order. Copy sheets of each copied page of the original document are sorted into a like number of collating bins wherein the copy sheets are stored in collated order. In response to commands entered by the user specifying the number of copies to be made of the original document and the selection of the first mode or the second mode, the feeding of copy sheets is repetitively operated for storing copy sheets respectively in the bins in the first or second order in which the pages of the original document are reproduced. In response to selection of the first mode for the first copy job copies of information associated with a supplemental copy and/or print job are successively made on copy sheets and positioned in a first orientation in each of the bins consistent with respect to the pages of each copy made of the original document therein. In response to selection of the second mode for the first copy job copies of information associated with a supplemental copy and/or print job on copy sheets are successively made and positioned in a second orientation in each of the bins consistent with respect to the pages of each copy made of the original document therein. There is thus provided consistency in orientation of the two jobs in the bins.
