Abstract

In a xerographic copier having a recirculation automatic document feeder (RADF) which feeds original documents, with side-edge orientation, to a glass platen, at which location the documents are stopped for copying, the document's long leading edge is stopped at an operator-selected position, in order to form a blank binder-oriented margin on the appropriate edge of the copy sheet. The document glass has a normal registration position at which all document leading edges are stopped for conventional copying. The document's leading edge is, for example, the 11-inch edge when the original document is of the 8 1/2 by 11-inch size.

Copy Margin Shift

In a xerographic copier having a recirculation automatic document feeder (RADF) which feeds original documents, with side-edge orientation, to a glass platen, at which location the documents are stopped for copying, the document's long leading edge is stopped at an operator-selected position, in order to form a blank binder-oriented margin on the appropriate edge of the copy sheet. The document glass has a normal registration position at which all document leading edges are stopped for conventional copying. The document's leading edge is, for example, the 11-inch edge when the original document is of the 8 1/2 by 11-inch size. In order to provide a blank margin for binding of a multi-sheet copy set, the stopping position of original documents is changed to position the document's leading edge to the left or to the right of this normal registration position. The amount of shift is operator selectable in tenths of an inch, up to a maximum of 9/10 of an inch. When this function is selected by the operator, the copier's photoconductor erase timing is also changed to eliminate unwanted toned background adjacent the document's leading or trailing edges. Selection of this function, and selection of the shift amount, is by way of interaction between the copier's control panel and the operator, as assisted by a cathode ray tube (CRT) display which is located on the copier's control panel. This CRT display prompts the operator to enter certain information...
