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.

SPRING LOADED TORQUE RELEASE CLEANING BLADE HOLDER (Cont'd)

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.

Referring to the figure, the present spring loaded torque release cleaning blade holder 2 utilizes a spring 1 fixed to the ends 6 of the cleaning blade holder 2. The blade holder 2 is thus provided flexibility in a substantially vertical 3 direction with respect to the photoreceptor 10. The blade holder, in conjunction with anti-skew idler wheels 4, is also provided flexibility in a substantially horizontal 5 direction with respect to the photoreceptor 10. This flexibility provided to...
