Abstract

A timing hole embodiment for use in organic photoreceptor belts is disclosed. A timing hole is typically a hole or mark deliberately made in or on the non image areas of organic photoreceptor belts which serve as a reference point for sensing and tracking various photoreceptor operations, for example, counting belt revolutions, calculating belt speed, belt to developer and receiver sheet registration, and the like.

Proposed Classification

A timing hole embodiment for use in organic photoreceptor belts is disclosed. A timing hole is typically a hole or mark deliberately made in or on the non image areas of organic photoreceptor belts which serve as a reference point for sensing and tracking various photoreceptor operations, for example, counting belt revolutions, calculating belt speed, belt to developer and receiver sheet registration, and the like.

Timing holes known in the art comprise drilled or punched holes. These holes may have a disadvantage in that delamination of layered organic photoreceptors may occur at the hole location. An improved embodiment employs a reflective patch in place of a punched or drilled hole, which may be applied to the photoreceptor, manually or robotically, with a suitable adhesive material.
