Transaction printer

Abstract

A system for issuing printed documents exchangeable for value having interconnected printer and feeder modules. The printer module includes a printing station having a printhead supported for reciprocal movement in a direction transverse to the path of movement of the print medium. A sensor carried by the printhead is operative to sense and read preprinted indicia on the print medium. The feeder module includes a receptacle for storing the print medium as a continuous form. A slot is provided for enabling the insertion of print media external to the feeder module. A gate mechanism blocks the feed slot under predetermined operating conditions. A first drive mechanism is operative to feed the print medium from the receptacle towards the printing station. A severing mechanism is operative to sever the lead document from the supply. A severing sensor detects failure of the severing mechanism. A second drive mechanism in the printer advances the severed print medium through the printer to a location at which the printhead prints indicia on at least a portion of the print medium. Several security features are also provided to inhibit or prevent the unauthorized removal of print medium from the feeder module and to control access to the interior of the modules.
