A large capacity sheet delivery apparatus mounted on a photocopier has an upwardly biased, horizontal stack plate and movable feed rollers, rotated by a drive in the photocopier, that continue to engage the top sheet of the stack as the feed position of the top sheet lowers due to removal of sheets from the stack. A sheet stripping mechanism engages the feed roller assembly and is movable with it. The horizontal plate has linear bearings mounted on its rear edge for sliding on a pair of vertical rods.

Sheet delivery apparatus with horizontal plate

A method and apparatus are described for correcting a jam condition in a photocopier, the copier having a transfer station at which a developed image is transferred from a moving photosensitive surface onto a sheet material and a cleaning station having a cleaning blade bearing against the width of the photosensitive surface. The apparatus has energy transmitting and receiving elements which detect the presence of unremoved sheet material on the photosensitive surface between the transfer station and the cleaning station and provides for continued movement of the photosensitive surface until the sheet material strikes the cleaning blade. In this way, a buckle is formed in the sheet material between the cleaning station and the transfer station which facilitates removal of the sheet from the copier.
