Abstract

At machine start-up, the photoreceptor produces a very high torque spike. This torque spike can have a very damaging effect on a cleaning blade resting in contact with the photoreceptor surface, as well as to the photoreceptor itself. For example, a knick may be formed on the cleaning blade, or the blade may be caused to tuck under, which would then cause uneven forces to be applied to the photoreceptor, thereby causing streaks on the copy produced. Furthermore, variations in the photoreceptor torque may occur while the machine is running, due to variations of the amount toner present on the photoreceptor to be cleaned by the cleaning blade.
