Abstract

Photoreceptors commonly used in xerographic systems typically have an unprotected outer surface which may be easily damaged by scratching or similar abrasive handling. As such damage may render the photoreceptor unusable, due to a print quality defect caused by the scratch, the present disclosure proposes a pad-like device that may be used with xerographic systems having rail-mounted photoreceptor belt modules.

Photoreceptors commonly used in xerographic systems typically have an unprotected outer surface which may be easily damaged by scratching or similar abrasive handling. As such damage may render the photoreceptor unusable, due to a print quality defect caused by the scratch, the present disclosure proposes a pad-like device that may be used with xerographic systems having rail-mounted photoreceptor belt modules.

Typically, when the photoreceptor belts in such machines need to be serviced, the module is slidably removed from the interior of the system. While sliding the module out, the lower side of a loosened photoreceptor belt is susceptible to abrasion by any components lying beneath it, which may contact the photoreceptor's outer surface during removal.

The proposed solution to the abrasion problem is a detachable device which protects the exposed photoreceptor surface against contact damage from developer housings or similar components that lie near the photoreceptor module. More specifically, the device is a thin, non-abrasive pad which is sufficiently flexible so as to allow its placement over the outboard edges of a developer housing or similar components which might contact the photoreceptor upon removal from the xerographic system. Furthermore, two ends of the pad may be connected with a...
