Abstract
A printer having a transparency film discrimination system is disclosed. The printer includes a feed mechanism, an illumination source, a detector, and a processor. Light from the illumination source is reflected on or transmitting through the print medium (such as a transparent film) and is detected by the detector. The detected light is analyzed to determine the type of the medium. If the determined type of the print medium is not acceptable for the printer, then control signal is provided to the printer to halt the printing process as to avoid damage to the printer.
