ABSTRACT:
A card reader and validator for use in wagering terminals includes a housing with a paper path. A paper drive surface of a drive wheel projects into the paper path. A platen assembly includes a pressure roller for pressing paper against the paper drive surface of the drive wheel and a platen surface for pressing paper agianst the paper path at a processing zone. The platen assembly is pivotally mounted to the housing in a manner such that it is biased toward the paper path when the drive wheel rotates in one direction and is lifted away from the paper path when the drive wheel rotates in the opposite direction. Corresponding ribs in the platen surface and paper path flatten the paper in the processing zone to facilitate the reading of optical marks on the paper by optical sensors. An ink jet printhead is provided for printing indicia on a portion of paper traveling through the paper path. A wick mounted to the platen assembly absorbs ink from the ink jet printhead during a purge cycle.
