    摘要： An electrophotographic printing machine that has a photoconductive belt with a skewed seam thereon. The position of the skewed seam is detected by a pair of seam detection devices. The seam detection devices are spaced from one another and adapted to transmit a pair of signals with the signals having a time interval therebetween. These signals are inputted to a detection circuit and, if the time interval between signals is within a preselected tolerance, the detection circuit generates a seam indication signal. In this way, scratches on the photoconductive surface may be discriminated from the seam.

    摘要： A platen cover for an imaging device such as a copier or scanner includes a substrate and at least of portion of the surface of the substrate is coated with a fluorescent coating. Preferably, the substrate has a dark or black color. The dark color of the substrate substantially reduces or eliminates show through of an image on the backside of an original document when the platen cover is not exposed to a light source for imaging. At the same time, when holes or uneven borders are present in the original document, the fluorescent coating fluoresces upon exposure to the light source at these regions of the original document, making these portions appear white in the replicated image and thereby substantially reducing or eliminating the unsightly appearance of these portions as black portions in the replicated image.
