Abstract:
1. A stripper assembly arranged to strip a media sheet from a photoreceptor belt; the stripper assembly comprising a support bracket arranged to support an included stripping finger base; the support bracket arranged to be fixed proximate to the photoreceptor belt in a media stripping position; the stripping finger base having a multiplicity of individual stripping fingers attached thereto, each stripping finger having a protruding distal stripping end and an opposite stripping finger base end, with an upper media stripping surface extending therebetween, so that with the support bracket in the media stripping position the corresponding finger distal stripping end extends toward the proximate photoreceptor belt to thereby form a gap with the photoreceptor belt; the support bracket comprising an inboard guide pin and a parallel outboard guide pin, the corresponding inboard and outboard guide pin distal ends protruding outward away from the support bracket; the stripping finger base having an inboard guide pin hole and an outboard guide pin hole arranged for respectively engaging the inboard and outboard guide pins, thus enabling the stripping finger base to move along the inboard and outboard guide pins either towards or away from the support bracket; the support bracket arranged to pivot about a pivot axial located at an included support bracket inboard end, the opposite support bracket outboard end being releasable to thus enable the support bracket to pivot away from the photoreceptor belt; including an inboard guide pin load spring positioned at the inboard guide pin distal end and an outboard guide pin load spring positioned at the outboard guide pin distal end, the inboard and outboard guide pin load springs arranged to apply corresponding inboard and outboard load spring expansion force against the stripping finger base, thereby urging the stripping finger base to move towards the support bracket; including an inboard guide pin clamp positioned between the inboard guide pin load spring and the stripping finger base and an outboard guide pin clamp positioned between the outboard guide pin load spring and the stripping finger base, the inboard and outboard guide pin clamps arranged to control the application of the corresponding inboard and outboard load spring expansion forces against the stripping finger base; and including an inboard guide pin return spring positioned at the inboard guide pin base end and an outboard guide pin return spring positioned at the outboard guide pin base end, the inboard and the outboard guide pin return springs arranged to apply corresponding inboard and outboard return spring expansion forces against the stripping finger base, thereby urging the stripping finger base to move away from the support bracket.
