Abstract: An apparatus for cleaning a charge retentive surface of a photoreceptor which includes a rotating brush for cleaning the charge retentive surface of a photoreceptor. A spring or other device is used to maintain constant, uniformly distributed contact between the charge retentive surface and the rotating cleaning member together. The use of one or more pressure rollers to maintain the cleaning brush next to the photoreceptor belt can prevent undesirable friction, heat and/or static charge buildup adjacent to the photoreceptor, and can prevent photoreceptor jamming and other malfunctions. The resulting self regulating cleaning brush contact improves photoreceptor cleaning effectiveness despite brush aging, bristle wear or set, or other factors effecting the radius of the cleaning brush or its relative positioning in the photoreceptor cleaning assembly. The present invention results in the uniform distribution of the contact pressure on the photoreceptor, which may monitored and/or be controlled.

Abstract: In an auto-fitting mode, a scanner prescans an input document to determine the location and size of an image within the input document. The area of the image is defined in terms of a rectangular area encompassing all area of the input document where the reflectance of the image data is less than 20% of the reflectance value of the input documents background. Once the image area has been defined, a magnification factor is calculated. The input document is then rescanned applying the calculated magnification factor and properly registered so that the image area can be centered when it is rendered on to the desired output paper. If the image area detected is such that the longer side of the rectangular area does not have the same orientation as the desired output paper, the image is automatically rotated prior to the magnification and registering processes. The magnification factor can be calculated either anamorphically or isotropically.

Abstract: Disclosed is a method of creating simulated, photographic-quality prints using transparent polyester substrates such as Mylar.RTM.; polypropylene, and the like. Reverse or wrong reading images are formed on the substrate using a linear or crosslinked low melt polyester toner and mixtures thereof.
