Abstract
A printing device includes a controller, a light emitter and a color sensor. The controller controls print functions. The light emitter is situated to emit light on media fed into the printing device. The color sensor detects light from the light emitter reflecting off the media. The color sensor generates a feedback signal for use by the controller.
Claims20
A color calibration system within a printing device comprising:
- a controller that controls print functions;
- a light emitter situated to emit light on media fed into the printing device;
- and,
- a color sensor that detects light from the light emitter reflecting off the media, the color sensor generating a feedback signal for use by the controller, the controller using the feedback signal for color calibration of images placed on the media.
