Abstract
A print media detection apparatus may include a movable scanner bar for scanning media, a feeder tray for supplying the print media, a print media indicator and a controller. The print media indicator may include a first portion to interact with the print media within the feeder tray and a second portion coupled to the first portion to move in response to movement of the first portion. The scanner bar is to sense the second portion of the media indicator. The controller is to determine a characteristic of the print media within the feeder tray based upon sensing of the second portion by the scanner bar.
Claims15
A print media detection apparatus comprising:
- a movable scanner bar for scanning media;
- a feeder tray for supplying the print media;
- a media indicator comprising:
- a first portion to interact with the print media within the feeder tray;
- and
- a second portion coupled to the first portion to move in response to movement of the first portion, wherein the scanner bar is to sense the second portion of the media indicator;
- and
- a controller to determine a characteristic of the print media within the feeder tray based upon sensing of the second portion by the scanner bar.
A print media detection method comprising:
- moving a media indicator based upon interaction of the media indicator with print media within a media tray;
- moving a scanner bar to sense the media indicator with the scanner bar;
- sensing the media indicator with the scanner bar;
- and
- determining a characteristic of the print media within the media tray based upon the sensing of the media indicator with the scanner bar.
A non-transitory computer-readable medium containing print media detection instructions to direct a processor, the print media detection instructions comprising:
- scanner bar instructions to direct the processor to move a scanner bar to sense a media indicator that interacts with print media within a feeder tray that supplies the print media for being printed upon;
- media indicator sensing instructions to direct the processor to cause the scanner bar to sense the media indicator;
- and
- media characteristic determination instructions to direct the processor to determine the characteristic of the print media based upon sensing of the media indicator.
