Abstract
A document handler, such as used in a digital copier, includes an input tray and an output tray, connected by a paper path. Along the paper path are disposed two scan heads, one to record image data from each side of the sheet. The two scan heads are separated from each other along the paper path by a pitch length longer than a sheet to be scanned. The arrangement allows an image on each side of the sheet to be scanned at an exclusive time. For long sheets, a recirculation path, associated with the paper path, is used to allow the sheet to re-enter the paper path: in this way, one side of the sheet is scanned with one scan head, and then the other side is scanned with the other scan head.
