Abstract

Typically, photoreceptor blade cleaning is compatible with continuous band photo-receptors, i.e, one which does not have an open seam. Where a replenishable photo-receptor is used, a scroll stores the used and unused portions of the photoreceptor on separate rolls inside a support drum. One or two gaps then exist at the location

Typically, photoreceptor blade cleaning is compatible with continuous band photo~ receptors, i.e, one which does not have an open seam. Where a replenishable photo~ receptor is used, a scroll stores the used and unused portions of the photoreceptor on separate rolls inside a support drum. One or two gaps then exist at the location

where the photoreceptor enters and exits the interior of the support drum. The tip of a typical cleaner blade could easily hang up in the gap causing blade fold under with resultant damage to the cleaning system. To obviate this, a closure plate 5 is pivotally mounted in the gap 6 of the photoreceptor support drum 7. To prevent the cleaning blade 8 from "catching" in the gap, plate 5 is designed such that the blade 8 always rides off and not into the lap joints 9 between the drum edges and

the sides of plate 5.
