Abstract
A printer is disclosed having an improved paper feed mechanism. The improved paper feed system has a reduced cost and accepts a wide variety of paper types including continuous forms and single cut sheets fed both by hand and from a paper tray. Furthermore, the printer is capable of switching from one paper source to another without requiring the operator to unload and reload paper. The mechanism operates with only two motors and no solenoids. Control over the paper path is maintained by employing the carriage to select the paper path and lift the ball. The printer also has a novel paper sensor.
