Abstract: A system and method for manually removably locking a paper handling module to a reproduction apparatus with greatly reduced manual force, wherein the reproduction apparatus and the paper handling module have respective sheet feed openings which are operatively aligned for sheet feeding therebetween when the module is so locked to the reproduction apparatus in a locking position, and wherein the paper handling module has a weight which is undesirable for manual lifting into the locking position. The module is supported on an integral module transporting system to be freely movable in any horizontal direction into an initial docking position closely adjacent to the reproduction apparatus.

Abstract: A bearing mounting system for mounting and retaining a rotatable shaft between first and second bearings mounted to first and second spaced frame members of a machine frame, utilizing commercially available bearings, with respective inner and outer races. Both bearings inner races are press fitted onto the shaft. A first bearing mount rigidly secures a first bearing outer race to one of the frame members. A second bearing mount provides for axial movement of the second bearing outer race relative to the second frame member but prevents rotation of that outer race. The second mount includes a round aperture in the second frame member through which the second bearing outer race is axially moveable, and a notch aperture adjacent to the round aperture, and a clamp removably clamped to the outer race and moveable therewith. The clamp is axially but not rotatably moveable within the notch aperture in the second frame member.

Abstract: In a document handling apparatus for registered feeding of document sheets to the imaging station of a copier with a document imaging station transport, and a document sheet acquisition and initial registration system for feeding document sheets to the document imaging station transport, the improvement wherein said document sheet acquisition and initial registration system includes a sheet inversion path with a sheet inverting roller and spaced plural sheet retaining belts partially wrapped around the inverting roller to provide separate document sheet lead edge capturing nips therewith, and to provide a non-slip document feeding path when a document is held between the plural belts and the roller, and with apparatus for mounting a central one of the plural belts differently from the other belts for centrally engaging a document sheet in a registration nip with the central belt prior to engagement of a document sheet in the capture nips of the other belts.
