Abstract: Multiple copies of sheets produced by a copying machine or the like are sorted onto trays. The trays are arranged in a stack and are moved upwardly and downwardly to enable different sheets to be sorted onto the trays on each upward pass and downward pass of the stack. The trays have pairs of pins extending outwardly from opposite side edges into a pair of slots on upright support plates. The walls of these slots support each tray as a cantilever. One of the slots, which is closest the rear edge of the trays, is preferably larger than the other and enables any adjacent trays to be spread apart by lifting and tilting one of the trays so as to provide access between the separated trays for jam clearance and the like. A shifting mechanism moves the trays across a gap into which sheets are dispensed from the copier onto the tray at the underside of the gap. This lifting mechanism is a rotatable assembly which engages the pins and moves a tray across the gap.

Abstract: An improved cleaning roll assembly for cleaning the residual toner particles from the heated fuser roll of a heated pressure fusing system in an electrostatic copy machine. A carriage supports a plurality of cleaning rollers in contact with the surface of the heated fuser roll. A pressure loading mechanism applies a force on the carriage and cleaning rollers against the surface of the heated fuser roll. Each of the cleaning rollers is rotatable on a shaft assembly which is connected to the carriage by a flexure member mounted on a shaft journaled in the carriage. The shaft assembly has a displaceable plunger member to receive and lockingly engage the cleaning roller on each end thereof.

Abstract: An improved cleaning roller for cleaning the residual toner particles from the heated fuser roll of a heated pressure fusing system in an electrostatic copy machine. The cleaning roller is mounted on a carriage supporting one or more cleaning rollers in contact with the surface of the heated fuser roll. A pressure loading mechanism applies a force on the carriage and cleaning rollers against the surface of the heated fuser roll. Each cleaning roller has a core member which is covered with a sleeve of soft suitable material such that under the pressure loading condition the surface of the cleaning roller conforms to that of the heated fuser roll. The exterior surface of each cleaning roller has a toner coating mixed with silicone oil to insure proper release of the residual toner from the heated fuser roll onto the cleaning roller.
