Abstract

Electrophotographic printing machines employing a seamed belt photoreceptor also have a seam tracking system to prevent imaging at the seam. It is proposed to use the seam tracking system to protect the donor roll surfiace andor high voltage pulsed bias supply of a Hybrid Jumping Development (HJD) system. The seam tracking system would interrupt the pulsed bias power supply, at the HJD, whenever the photoreceptor seam passes through the development nip. This provides protection against spurious electrical arcing caused by a diminished size of the development gap (donor roll to photoreceptor spacing) when an overlapped photoreceptor seam passes through the nip.
