Abstract:
1. A sheet processing apparatus comprising a print engine, a sheet punching device for punching a set of two or more spaced holes arranged on an imaginary line in sheets processed by the apparatus, and further comprising a processor unit for controlling the apparatus, including the punching device, wherein the processor unit controls the apparatus in punching the set of holes in all sheets of a first batch, in a first position, the sheets of the first batch having substantially equal size and orientation, said processor unit enabling an operator of the sheet processing apparatus to specify: at least one second batch of sheets having substantially the same size and orientation as the sheets of the first batch, a shift of the position in which said set of holes is to be punched in the sheets of the second batch, to a second position, and a shift of the position of any printed images, for aligning the images on all sheets when the holes of all sheets are aligned, and to control the apparatus in printing shifted images and punching the set of two or more spaced holes in the second position in the sheets of the second batch, thereby creating a staggered stack of sheets with the images on all sheets aligned, when subsequent first and second batches of sheets are stacked with holes aligned, when placing them in a ring binder; wherein a specified second batch of sheets is a sub-set of a processing job, for creating a staggered stack of documents with aligned holes.
