Abstract
A system and method for determining proper positioning of the printhead as it travels between first and second positions by sampling an electrical resistance signal of a motor during tilting of the printhead, calculating an average of specified samples at a time, and comparing the calculated average to a predetermined threshold to determine whether the printhead is operating properly. Thus, the need for sensors to determine the positioning of the printhead is eliminated.
