The platen defines a scan area over which the image sensing device is capable of scanning an image. The image sensing device includes a plurality of calibration marks falling within the scan area. The method further includes operating the scanner to scan the test sheet; determining a scanned position of the calibration marks and a scanned position of the test marks resulting from the scan; comparing the scanned position of the calibration marks with reference position of the calibration marks to determine scanning error; determining an adjusted position of the test marks responsive to the scanning error; and comparing the adjusted test mark positions with predetermined reference positions to measure registration accuracy. An edge guide disposed on the platen assists in aligning the test sheet for scanning."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for measuring image on paper registration","description":"A method and apparatus for measuring image on paper registration including placing a test sheet of media including a plurality of test pattern marks on a platen of an image sensing device.
