Abstract
A ribbon sensor includes a first and second emitter and a receiver. The first emitter is configured to transmit a yellow light signal and the second emitter is configured to transmit a blue light signal. The receiver is configured to produce an output signal in response to the transmission of the yellow and blue light signals through a panel of a print ribbon, wherein the output signal is indicative of a color of the panel. Additional aspects of the present invention are directed to a printer that includes the above-described sensor and a method of using the sensor to identify colored ribbon panels.
