Abstract: A toner usage sensing system for an electrostatic reproduction apparatus which utilizes multicomponent developer material including electrostatically charged toner to develop electrostatic latent images on a photosensitive plate directly senses the amount of toner consumed by the reproduction process. Since the average toner body charge (coulomb/gram) is constant for a given desired toner concentration, the weight of the electrostatically charged toner consumed in sensed by measuring the charge removed from the developer material during the reproduction process. The developer unit containing the developer material is electrically isolated from the remainder of the reproduction apparatus and grounded through a single connection. The current in the ground connection returns charge to the developer unit sufficient to replace the charge removed and is sensed to obtain a measurement of the toner consumed. A measured amount of toner is added to the developer material when a preselected amount of charge has been sensed as being removed. In one embodiment, a DC motor drives the toner replenisher and rotates an amount proportional to the sensed current thereby providing a mechanical storage of the incremental amounts of toner removed on widely spaced reproduction runs.

Abstract: This is an electrophotographic process comprising the step of contacting a latent electrostatic image with a developer comprising carrier and toner. The carrier is a core coated with a continuous film of a fluoropolymer and a modifying resin. This carrier has a positive triboelectric charge with respect to the toner. This positive charge is obtained by curing the coated carrier at a temperature less than 700*F.

Abstract: Cleaning apparatus for cleaning the residual toner image from an electrostatic plate of an electrostatic reproduction apparatus incorporates an open celled foam wiper which is mounted for wiping engagement with the plate. The foam wiper is mounted adjacent a conductor which is biased to attract charged toner particles to the wiper as the toner image moves relative therepast. The wiper is periodically cleaned by a serrated or grooved portion of the plate which follows the image and mechanically dislodges toner from the wiper. A reverse bias is applied to the conductor as the serrations on the plate move past the wiper creating a field between the wiper and the plate which repels toner from the wiper to the plate. The toner is carried by the serrations on the plate to the developer unit for use by the electrostatic reproduction apparatus.

Abstract: An image producing process of a document copier is controlled by means detecting a low average intensity of reflected light during initial stages of scan of an original being copied to produce a low density or light copy adjacent the leading edge of the copy sheet passing through the machine thereby minimizing paper feed difficulties associated with the passage of copy having a dense leading edge through a contact fuser.

Abstract: A continuously operating transfer reproduction apparatus includes a cyclic control unit which automatically effects alternate redevelopment and reimaging cycles when reproducing multiple copies of the same master. An electrophotographic plate travels in a closed loop past a moving optical system which images the plate with a light image of the master creating a latent electrostatic image on the plate. The latent image is developed at a developing station and transferred to a substrate at a transfer station as the plate travels therepast. Increased throughput speed is achieved by effecting a fixed number of redevelopment cycles while the moving optical system is resetting. Thus, the plate continues its travel past the resetting optical system to the developing station where the latent image is redeveloped and thence to the transfer station for transfer of the developed image to a second substrate. The plate is then cleaned and charged prior to being reimaged with the light image of the same master, and the process continues until the requisite number of copies have been reproduced. In one embodiment, multiple imaging areas, preferably an odd number thereof, are located on the plate facilitating rapid alternate imaging and redevelopment cycles.

Abstract: The invention concerns a method and apparatus for operating a multibin sheet collator, particularly a copier/collator installation. Additional to the number of sets to be collated, the number of sheets contained in each set is entered into the collator logic. If this number of sheets in a set exceeds the capacity of a single collator bin, adjacent bins are grouped together and treated as one virtual bin with increased capacity, thus extending the collator usage. Sheets exceeding the total capacity of the collator can be fed into additional receptacles.
