Abstract: A printing apparatus provided with a deposition unit for printed sheets comprising a number of copy trays situated one above the other, which trays are adjustable in height independent of one another to a deposition position with respect to the sheet delivery rollers disposed at a fixed height, and to a parking position. Upon the activation of the printing apparatus by a start key provided on the printing apparatus, a control system sets the bottom copy tray into a deposition position and the other copy trays into a higher parking position. Upon the activation of the printing apparatus by a start key disposed at a distance from the printing apparatus at a workstation, the control system selectively sets one of the other copy trays into a deposition position and the bottom copy tray into a lower parking position.

Abstract: A copying machine is provided with a sheet stapling device for both automatically fastening together in a corner area a bundle of sheets successively printed in the copying machine and fastening together a bundle of sheets manually inserted in an externally accessible opening formed in the side of the stapling device. Preferably, the opening is formed by an elongated slot which extends to the operating side of the copying machine and which coincides with the opening through which sheets printed in the copying machine are discharged from the stapling device. A bundle of sheets can be inserted in the opening so that any edge part is under the stapling means. Thus, the inserted bundle can be stapled at different places along any edge. The opening is provided with two detectors to determine when a bundle of sheets inserted manually is correctly positioned under the stapling device and to initiate the stapling action.
