System and related methods for automatically determining the media count in a printing device media tray |
摘要 |
A system for determining the amount of media available to a printing device is presented. The system comprises a sensor and a disc containing one or more visual cues perceptible to the sensor. The disc is rotated by a coupled lifting member to lift a media handling tray to present any media stored thereon to a receiving printing device. The sensor generates a signal based, at least in part, on the visual cues provided from the rotated disc.
