A bottle for collecting untransferred developer material and debris cleaned from a dielectric member of a reproduction apparatus. The collection bottle is a container having an opening adapted to receive untransferred developer material and debris therethrough for storage within the container. The container is made of a conductive material. The conductive material is a carbon-doped plastic having a volume resistivity of less than 10 omhs cms with the carbon dopent being approximately 15-20% by weight. The container is coupled to electrical ground via an electrical tap, whereby static charge build-up is substantially prevented.

A control system for an optical sheet sensor device, including at least one light emitter and at least one light detector associated therewith for sensing a sheet in a sheet travel path for automatically controlling the sheet sensor device in order to provide an intensity of light from the light emitter to compensate for varying background reflectance and background-to-light emitter distance. The control provided for determining a light emitter current level corresponding to an operating condition where a sheet is known to be absent from the sheet travel path and where there is a close, reflective background to the light emitter. A light emitter current operating level corresponding to a reduced level with respect to the above determined current level is stored. A current startup error level at a preset amount off-set from the stored current level is determined. Current is applied to a light emitter, the applied current being increased toward a level at which the threshold level for the light detector is exceeded. The instantaneous applied current level is compared with the determined startup error current level, and an error signal is provided when the light intensity threshold is reached prior to the applied current level exceeding the determined current level. If the determined startup error current level is exceeded by the applied current level prior to the light intensity reaching the light intensity threshold, the light emitter is operated at the applied current level.

A fuser for fixing a toner image to a receiver sheet includes a housing, a fusing roller mounted for rotation within the housing, and a rotatable wick for applying offset-preventing liquid to the fusing roller. The rotatable wick is adjustable between a first position in frictional contact with the fusing roller, wherein the rotatable wick is rotated by the fusing roller and applies an amount of offset-preventing liquid to the fusing roller, and a second position spaced from the fusing roller. An actuation structure selectively moves the rotatable wick between its first and second positions. A motor and a transmission interconnecting the motor and the rotatable wick, at least when the rotatable wick is in its second position, are provided to effect rotation of the rotatable wick to inhibit settlement of offset-preventing liquid in the rotatable wick.

A control system for an optical sheet sensor device, including at least one light emitter and at least one light detector associated therewith for sensing a sheet in a sheet travel path, having a control system for automatically adjusting the intensity of said light from said light emitter. The control system stores a light emitter current level corresponding to a known valid operating condition where, when a sheet is absent from the sheet travel path, light detected at a light detector beyond a threshold level. A current level at a preset amount off-set from said stored current level is determined. A current is applied to a light emitter, the applied current rising toward a level at which the threshold level for the light detector is reached. The instantaneous applied current level is compared with the determined current level, and an error signal is provided when the applied current level reaches the determined current level. If the determined current level is not reached by the applied current level, the light emitter is operated at the applied current level, and if the determined level is reached, such error signal is provided.

An apparatus for diverting paper along at least two paper paths in photocopiers, the apparatus comprises a paper diverter for diverting paper from one path to another path. A magnet is attached to and moves the paper diverter which movement, in turn, permits the paper to be directed from one path to another paper path. Means for creating a magnetic field interacts with the magnet for permitting the magnet to move in response to the magnetic field for enabling the magnet to move the paper diverter for ultimately permitting paper re-direction.
