Abstract

The lapped seam on an organic photoreceptor belt cannot be imaged. A timing hole known in the art comprises a drilled or punched hole deliberately made in or on the non imaging area of an organic photoreceptor belt to serve as a reference point for belt tracking. The timing hole has the disadvantage in that delamination of the layered organic photoreceptor may occur at the hole location. Furthermore, defects on the nonimaging area of the organic photoreceptor belt may cause false detection. An improved embodiment employs the use of an electrostatic voltmeter to locate the belt seam by detecting the charge accumulation at the seam.
