Abstract: A system for controlling a sorter for receiving copy sheets from a reproduction machine processor. The sorter includes a plurality of bins for holding collated books of copy sheets. The control system provides a fault detection feature which insures that the copy sheets are placed in the correct bin. As each sheet enters the sorter, a timer is caused to begin running. When a sheet enters a bin, the timer is read and a fault is declared if the sheet did not reach the bin within a predetermined time range. Other features include bin module selection capabilities and automatic starting of the processor after a module has been unloaded.

Abstract: An electrostatographic type copying or reproduction machine for making duplex as well as simplex copies. To enable offset margins on the original documents being copied to be matched on both sides of a duplex copy, a control is provided which when actuated moves the second side image into alignment with the first side image.

Abstract: In an electrostatic reproducing machine an improved fusing apparatus is provided for fusing xerographic images onto copy sheets. The fusing apparatus comprises various actuable means including a pressure roller, a fuser roller, means for engaging and disengaging the pressure roller against the fuser roller, means for cooling end portions of the pressure roller, means for lubricating the fuser roller, and control means for actuating the various actuable means in a timed order and sequence to effect the fusing operation.
