Patent ID: 7967289

Claim:
A printing apparatus, comprising: at least one releasable media drive nip including a drive roll and an idler roll in mating engagement with said drive roll and adapted to drive media for capture by a downstream nip; a drive member operatively connected to said drive roll, wherein said drive member is adapted to rotate in a forward direction when moving media through said media drive nip; an idler mounting member operatively connected to said idler roll and supporting said idler roll such that rotation of said drive roll rotates said idler roll; a cam operatively connected to said idler roll, wherein as said cam rotates, said cam moves said idler roll between a first position of mating engagement with said drive roll and a second position out of contact with said drive roll; a drive motor operatively connected to said drive member, wherein said drive motor is adapted to drive said drive member in said forward direction when rotated in a first direction and said drive motor is adapted to drive said cam when rotated in a second direction; and at least two single direction devices supported by said drive member and operatively connected to said drive motor, wherein one of said at least two single direction devices is operative only when said drive motor is rotated in a first direction and the other of said at least two single direction devices is operative only when said drive motor is rotated in a second direction in order to allow said media drive nip to be activated for release while said media is under said media drive nip and a lead edge thereof has been simultaneously acquired by said downstream nip.
