Width detecting media hanger
First Claim
1. A printer comprising:
- a processor;
a media hanger comprising a body for supporting loaded media and a sensor array receiving space extending along a length of the body; and
a sensor array positioned in the sensor array receiving space and communicatively connected to the processor, the sensory array comprising a plurality of sensor pairs, each sensor pair having an emitter and a receiver, the sensor array being configured to;
emit light from the emitter outward from the media hanger,detect the emitted light after the emitted light is reflected off a surface of a roll of media loaded on the media hanger,transmit signal intensity of the reflected light detected by each of the sensor pairs to the processor;
wherein the processor is configured to determine a width of the roll of media loaded on the media hanger based on the signal intensity detected by each of the sensor pairs.

11. A method comprising:
-
emitting light from an emitter in a direction outward from a media hanger towards a roll of media supported by the media hanger, the emitted light being generated by a plurality of sensor pairs, each sensor pair comprising the emitter and a receiver; detecting the emitted light with the receiver after the emitted light has been reflected off a surface of the loaded roll of media; transmitting a signal intensity of the emitted light detected by the receiver in each of the sensor pairs to a processor, the receiver from each sensor pair detecting light emitted from the corresponding emitter in the sensor pair; and processing the signal intensities detected by the receiver from each sensor pair to determine a width of the loaded roll of media. - View Dependent Claims (12, 13, 14, 15)

16. A media hanger assembly comprising:
-
a processor; a body for supporting loaded media, the body comprising; a sensor array receiving space extending along a length of the body, and a light passing window extending along the length of the body; and a sensor array positioned in the sensor array receiving space and communicatively coupled to the processor, the sensory array comprising a plurality of sensor pairs, each sensor pair having an emitter and a receiver, the sensor array being configured to; emit light from the emitter outward from the media hanger, detect the emitted light after the emitted light is reflected off a surface of a roll of media loaded on the body, transmit signal intensity of the reflected light detected by each of the sensor pairs to the processor; wherein the processor is configured to determine a width of the roll of media loaded on the body based on the signal intensity detected by each of the sensor pairs. - View Dependent Claims (17, 18, 19, 20)
