Abstract

A method of determining a registration offset in a hard copy apparatus (10), the apparatus comprising a pen arranged to mark a print medium (30) and a sensor (50) arranged to detect marks on the medium along a sensor path (65), the method comprising the steps of: marking an alignment pattern (61-64) on the medium, the pattern being at least partially located along the sensor path; detecting the position along the sensor path of a portion of the pattern; and, determining a distance by which the pattern is offset from the sensor path in a direction substantially perpendicular to the sensor path, the pattern being configured such that the detected position is indicative of the offset distance. <IMAGE>
