Zusammenfassung:	In one example, a printer with adaptive sampling includes a print engine, a monochrome scanner, a light source, and an analysis module. The light source has independently controlled primaries oriented to illuminate a media from the print engine. The analysis module includes a page selection module to select a chosen page of media for analysis, a heuristic analysis module to analyze the chosen page and determine a region of the page for analysis, a light control module to select a mono-color for the light source in region on the chosen page, and a quality module to accept an image of the chosen page and a scan of the chosen page with the monochrome scanner illuminated by the selected mono-color and compare the image and the scan within the region to determine a discrepancy.
