Patent ID: 6866260

Claim:
An integral sheet registration system for providing sheet forward feeding, sheet deskewing by partial sheet rotation, and sheet lateral registration by lateral sheet movement, with first and second spaced apart sheet feeding nips; wherein said first and second sheet feeding nips are both rotatably driven for said forward sheet feeding by a single and stationary nips drive motor, wherein said first and second sheet feeding nips are laterally repositionable for said sheet lateral registration by a lateral repositioning system, wherein said first and second sheet feeding nips are variably differentially rotatable with respect to one another by a differential drive system for said sheet deskewing, and wherein said differential drive system comprises a variably laterally translatable helical drive interconnection between said first and second sheet feeding nips to provide said variable differential rotation of said first and second sheet feeding nips with respect to one another and said rotatable driving of said first and second sheet feeding nips by said single and stationary nips drive motor.
