Abstract:
A sheet jam access assembly is used with a digital printer having a finisher transport assembly with a main transport cover. First and second axles with idler nip rollers are mounted on the transport for movement away from the process path. First and second drive nip rollers are mounted for driven rotation on the transport. A jam access cover pivots on the main transport cover from a closed to an open position. First and second hinges each has a first outer leaf on the jam access cover connected by a hinge pin to an inner leaf which translates transverse to the process direction. The hinge axis is spaced apart from the cover axis. A cam plate base portion translates parallel to the process direction. First and second ramps adjacent the axles extend away from the base portion at an angle to the process direction. A slot extends through the first inner leaf at an angle to the process direction. A transfer pin attached to the base portion engages the slot to move the cam plate ramps, which engage the axles to raise the nip rollers and release the jammed sheet. A leaf spring detent holds the jam access cover open.
