Abstract
A media tracking sensor (MTS) apparatus for performing a calibration procedure to determine a resolution calibration factor includes: a full sensor array including: a first virtual array, having a first width, for capturing a calibration reference image; and a second virtual array having a third width equal to the first width, for capturing a plurality of images and comparing the captured images with the calibration reference image. The MTS apparatus further includes a print media positioned below the full sensor array; and a host system for moving the print media below the full sensor array. When the first virtual array captures the calibration reference image, motion data of the full sensor array will be set to zero, and when an image captured by the second virtual array matches the calibration reference image, total motion data will be recorded and used to determine the resolution conversion factor.
