Abstract
An apparatus for a scanning-head printer in which a single motor is used to provide movement to a print head carriage and to advance the paper along a paper path. The single motor is coupled to the print head carriage to provide movement of the carriage back and forth across the width of the paper. As the carriage is moved across the paper, the print head applies print to the paper. An advancement mechanism is located near the edge of the paper path. As the print head carriage reaches the edge of the paper, the carriage contacts the advancement mechanism which, in turn, causes the paper to be advanced along the paper path. Thus, a single motor advances the paper and moves the carriage across the paper.
