Patent ID: 7511864

Claim:
An apparatus for recording data from images on sheets, comprising: an input tray and an output tray; a paper path, suitable for moving a sheet therethrough from the input tray to the output tray; a first scan head, disposed on a first side of the paper path, and a second scan head, disposed on a second side of the paper path, the first scan head and second scan head each outputting digital image data related to light reflected from an image moving therepast; a first recirculation path associated with the paper path, whereby a sheet of a first size in the paper path can be moved past the first scan head and recirculated and moved past the second scan head, whereby the first scan head is finished recording an image before the second scan head begins scanning an image; and a second recirculation path associated with the paper path, whereby a sheet of a second size longer than the first size in the paper path can be moved past the first scan head and recirculated and moved past the second scan head, the second recirculation path being longer than the first recirculation path, whereby the first scan head is finished recording an image before the second scan head begins scanning an image.
