Abstract
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.
