Abstract
Performing optical mark recognition (OMR) scanning includes receiving a first substrate to be scanned, the first substrate having one or more colors visible to a human eye and bearing user-made marks; scanning the first substrate using a plurality of colors of light emitted from a light sensor to simultaneously generate both (a) first image data representing a visual appearance of the first substrate, and (b) first OMR data corresponding to respective locations of the user-made marks on the first substrate; transmitting from a first page buffer at least a portion of the first image data and/or at least a portion of the first OMR data; receiving a second substrate to be scanned; and during the transmitting from the first page buffer, simultaneously scanning the second substrate.
