Sheet stack loader and sheet stack unloader arrangements provide load-while-run or unload-while-run capabilities. In a stack loader, a pusher element laterally pushes a stack or receiver into a sheet feed receiver. In a stack unloader, the pusher element pushes a finished stack from a stacking receiver to a removal receiver. By employing smooth paper support surfaces in the receivers, with close side-by-side positioning and an unobstructed path of movement, stacks of sheets of paper can be moved laterally by the pusher mechanism, which engages a side surface of the stack to be moved. Compact drive systems utilizing toggle drives and lead screws are utilized to minimize space requirements. Continuous run capabilities can be provided by auxiliary supply or stacking trays which are operative during the stack transfer sequence.

A copier is disclosed as having a sorter positioned on top of the copier housing for easy access to an operator. The path of movement of processed copy sheets is repeatedly folded in order to present to the operator collated copy sets or stacks for easy observation of sorting and removal. The sheets exit the copier processing station in a horizontal plane, are turned 90.degree. while still in the plane, are transported upwardly in a vertical plane, and deposited in sorter trays toward the operator.

Copier with sorting function

An apparatus in which an article is illuminated by a light source moving thereacross. Vibration of the light source is minimized during the movement thereof.

Lamp carriage drive system

An apparatus in which a fluid release material is applied to a fuser member. The fuser member is in communication with a backup member and a sheet of support material having particles thereon passing therebetween. A sealing arrangement prevents sidewise leakage of the release material along the longitudinal axis of the fuser member.

Release material application seal

An apparatus in which a metered quantity of release material is applied to a fuser roll. The release material is heated to maintain it substantially in a fluid state.

Heated fuser release agent container

An electrophotographic printing machine in which particles are cleaned from a half-tone image screen. The screen is movable from an operative position closely adjacent to the printing machine photoconductive member to an inoperative location remote therefrom. As the screen moves in one direction, a cleaning device moves in a direction opposed thereto so as to remove particles therefrom.

Screen cleaning device

A cover arranged to hold an original document in the platen of an electrophotographic printing machine. The cover includes an outer member defining a chamber with an inner member being mounted therein. The outer member cooperates with the platen to form a light-tight seal while the inner member presses the original document thereagainst.

Platen cover

An electrophotographic printing machine in which a screen moves from an inoperative position remote from a photoconductive member employed therein to an operative position closely adjacent thereto. As the screen moves from the operative position to the inoperative position, particles are cleaned therefrom. In addition, the spacing between the screen and photoconductive member is adjustable.
