Abstract

A copy sheet transport between the photoreceptor stripping point and the roll fuser for photoreceptor/f user speed mismatch compensation. A slack, curved belt is used as the transport to provide an initial sheet buckle, which buckle can be pulled out by fuser over-speed without pulling (sliding) the sheet trail edge on the photoreceptor.

A copy sheet transport between the photoreceptor stripping point and the roll fuser for photoreceptor/f user speed mismatch compensation. A slack, curved belt is used as the transport to provide an initial sheet buckle, which buckle can be pulled out by fuser over~speed without pulling (sliding) the sheet trail edge on the photoreceptor.

Here a sprocket~driven belt transport 1 is maintained slack in its copy sheet transport side or flight 2, while its opposite flight 3 is the tension sides A vacuum is applied through the slack side 2 to conform the copy sheet 4 to the beIt~sconcave configuration until the lead edge of the copy sheet reaches the fuser roll nip 5~The slack can be maintained by a separate drive belt 6 connecting the shafts of the two large diameter sprocket wheels 7 and S supporting the transport belt or belts L Alternatively, the slack can be maintained by driving the upstream wheel 7 while applying drag to the downstream wheel S.
