Abstract: A device for feeding sheets from a supply station aligning the sheets in an X, Y and .theta. coordinates and then gating the sheet into a work station such as the transfer station of a copier. The device includes a pair of independently servo-controlled motors disposed on opposite sides of the sheet. Each motor drives a nip roller which transports the copy sheet. Sensors are disposed to generate signals representative of sheet position in the X, Y and .theta. coordinates. A controller uses the signals to adjust the angular velocity of the motor so that the sheet is squared and is gated onto the work station. The sensors and controller are utilized to measure different parameters associated with the sheet.

Abstract: A compact single bin finisher adaptable to form collated sets of copy sheets outputted from a copier/duplicator. The finisher includes an output tray adapted to support the collated sets and to support copy sheets during accumulation of a set. A set accumulation module having an accumulation platform is disposed in a plane which is displaced both horizontally and vertically from the output tray. A transport device carries sheets into the accumulation module. A predetermined number of sheets form a set which may be stapled and is ejected onto the output tray.
