Abstract
A measurement module for a printer generally includes a page diverter mechanism configured to selectively divert a sheet of media from a main media path to a module media path; a rotating drum configured to receive the media from the module media path and to affix the media on an outer surface of the drum; a measuring device spaced adjacent to the drum and configured to measure as aspect of the media affixed to the surface of the drum; and a sheet transport configured to remove the media from the drum. According to one embodiment, the module may include a drum with an electrostatic hold-down mechanism that captures a sheet and an axially translating measuring device that is configured to read the entire surface as the drum rotates. The measurement module also allows the printed media to cool to eliminate problems with color measurements due to thermo chromaticity.
