Abstract
A device for calibrating a scanner, including a transparent plate installable in the scanner, for supporting a document containing indicia to be transferred, and an elongated calibration label fixed to the plate adjacent to, and parallel, with an edge thereof. The label includes an opaque white substrate having a bottom surface which includes a first zone containing white calibration ink and a second zone containing black calibration ink. The white ink contains machine readable information comprising data for controlling skew, magnification, and document reference while the black ink contains data for controlling black calibration. The top surface of the calibration label includes reference indicia for aiding a user in operating the scanner. The first and second zones are surrounded by an adhesive zone for adhering the label to the plate and for isolating the zones from environmental contaminants. A method is provided for fixing the label to a scanner plate for installation in a scanner bezel.
