Abstract

An apparatus and method for calibrating a peripheral device having a scanner and document feeder is provided. A target page is printed having a target at a known location on the page. The target page is then fed into the document feeder for scanning by the scanner. A calibration value is determined by determining the lateral position of the scanned target within the scanner. The calibration value is then used to adjust the lateral position of a scan line window width of the scanner to scan substantially only the entire width of a document page to be scanned.
