Abstract: A mechanism for advancing paper from a supply in incremental steps. The paper is initially fed into a loading slot formed by a paper guide and a rotating roller. The roller advances the paper through a paper stripper to a printing station.The rotation of the roller is accomplished by a ratchet mechanism which is activated by a double acting driver which in turn is driven by a solenoid assembly. The ratchet mechanism and driver also activate a retracting pressure bar which insures intimate contact between the paper and the printing station. The pressure bar pulls a paper stripper which positively strips the paper from the print station in preparation for paper advancement.
