Performing optical mark recognition (OMR) scanning includes receiving a substrate to be scanned, the substrate having one or more colors visible to a human eye and bearing user-made marks; moving the substrate and a light sensor relative to each other such that the substrate moves past the light sensor a single time; during the relative movement of the substrate, scanning the substrate using multiple colors of light to simultaneously generate both (a) image data representing a visual appearance of the substrate, and (b) OMR data corresponding to respective locations of the user-made marks on the substrate.

Single-pass imaging and optical mark recognition scanning

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.
