Abstract
Example implementations relate to an edge sensing apparatus. For example, an edge sensing apparatus consistent to the present disclosure may include a reflector in a beam path of a retroreflective sensor. The edge sensing apparatus consistent with the present disclosure may include a cover glass located between the retroreflective sensor and the reflector. The edge sensing apparatus consistent with the present disclosure may include a media feeder to feed a media along a media path between the cover glass and the retroreflective sensor.
Claims16
An edge sensing apparatus comprising:
- a reflector in a beam path of a retroreflective sensor;
- a cover glass located between the retroreflective sensor and the reflector;
- and
- a media feeder to feed a media along a media path between the cover glass and the retroreflective sensor.
An edge sensing apparatus comprising:
- a retroreflective sensor located on a scanner optical assembly-facing side of an automatic document feeder housing;
- a reflector in a beam path of the retroreflective sensor, wherein the reflector is located between scanner glass and a cover glass fixed to a scanner body;
- and
- a media feeder to feed a media along a media path between the cover glass and the retroreflective sensor.
An edge sensing system comprising:
- a retroreflective sensor located on scanner optical assembly-facing side of an automatic document feeder housing;
- a reflector in a beam path of the retroreflective sensor, wherein the reflector is located between scanner glass and a cover glass fixed to a scanner body;
- and
- a media feeder configured to feed media between the cover glass and the retroreflective sensor an acute angle relative to the cover glass to wipe debris from the cover glass.
