ABSTRACT:
A printing system transfer unit includes features which permit it to be coupled to the output sections of a variety of commercially available printing and copying machine. The system transfers thin foils onto printed indicia. The transfer unit has its own self-contained drive mechanism that may be operator adjusted to perform at the proper speed to permit the throughput of the transfer unit to match that of the printer and to minimize paper and foil jams and creases. A sensitive paper sensor is provided for initiating the transfer cycle. The transfer cycle includes the interposition of a transfer sheet and a printer output sheet between a heated roller and a pressure roller to effect transfer. The pressure roller, the transfer sheet and the heater roller are automatically separated from each other and remain in their inactive position, prepared to move into the transfer-cycle position in response to an output signal from the paper sensor.
