ABSTRACT:
A serial line printer uses a linear stepper motor of the variable reluctance type in which the toothed stator bar acts as a guide and support for the print mechanism carrier. Sensor elements movable with the carrier sense the presence of the teeth of the stator bar and generate timing signals usable for controlling operation of the printer and the motion of the carrier. The pitch of the teeth in the stator bar is proportional to the spacing of the print locations in a line of print.
