Document Type and Number:

WIPO Patent Application WO2002091729

Kind Code:

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.
