Abstract: Documents fed serially from a document reproduction machine 10 are fed by a vacuum belt feed system 21 to sheet accumulation and stapling system 22. When at the registration position in system 22, the leading edge of each sheet has passed output bin 14, and the trailing portion is supported either by platform 16 or sheet sets thereon. After a set is accumulated in system 22, it is stapled and then ejected back into bin 14.

Abstract: Electronic alignment of paper feeding components in a machine such as an electrophotographic copier machine is achieved by placing an original master containing vernier calibrations on the document glass and a target master containing vernier calibrations in the copy paper bin. Thereupon, the machine is operated to produce a copy of the original master onto the target master producing a double set of vernier calibrations on the target master, which, when compared, provides information relating to skew angle, side edge relationship and leading edge alignment of the image to the copy paper. The vernier calibrations provide data which are keyed into a microprocessor controlled copy feeding servo mechanism to correct copy paper position and remove misalignment. The operation is repeated for various combinations of paper feed paths with techniques of original document placement and for duplex operation so that the copy paper matches image position for all modes of copier operation. For printer mode of operation, the master vernier is printed to produce the needed image. In addition, sensors are located in the copy paper path to automatically correct for deviations in the copy sheet feeding unit, caused by wear, for example, over a period of time. Sensors are also located in the document feeder so that corrections in the position of the copy paper may be made on an individualized and dynamic basis to electronically correct for misalignment of individual originals on the document glass.
