摘要:
The present application is dieted to methods and devices for determining the absence of media sheets within an image forming device. In one embodiment, a support section configured to hold a stack of media sheets is positioned in an input area of the image forming device. A pick mechanism is positioned to contact a top-most sheet in the support section. The pick mechanism may include a pick motor and a pick roller. A sensor roller may fee positioned to contact the top-most media sheet at a position spaced away from the pick roller. A controller may determine the absence of a media sheet based on the movement of the sensor roller after a predetermined movement of the pick motor.
