A scanning device comprising a first image sensor, a second image sensor module and a housing. The first image sensor module has a first image array sensor for scanning information from a first side of media. The second image sensor module is mounted opposite the first image sensor module so that the media can move to a scanning region between the first image sensor module and the second image sensor module. The second image sensor module has a second image array sensor for scanning information from a second side of the media. A housing is attached to the second image sensor module. When the media moves to the scanning region between the first image sensor module and the second image sensor module and exits the scanning region, when the media reenters the scanning region, the media impacts a convex region of the housing that causes the second image sensor module to move with respect to the first image sensor module and to thus provide sufficient separation distance between the second image sensor module and the first image sensor module to allow the media to re-enter the scanning region.
