ABSTRACT:
According to aspects illustrated herein, there is provided a printmaking device, a method, and a system for calibrating sensors. The printmaking device includes a calibration system with a media path, a registration device, and at least one edge sensor. The registration device having a pair of nips connected by a lateral carriage and a calibration member disposed traversely and affixed to the lateral carriage. The lateral carriage is configured to move laterally relative to the media path. The at least one edge sensor may be configured to determine an extent of movement of a first portion of the calibration member. The registration device calibrates the at least one edge sensor by: moving the lateral carriage a predetermined distance; determining the extent of movement of the first portion of the calibration member; and comparing the predetermined distance and the extent of movement so as to determine the calibration factor.
