Abstract: An example apparatus includes a lift plate of a tray to hold a print medium. A support member is operatively connected to the lift plate. A sensor is attached to the support member to measure a distance of the lift plate from the sensor. A processor may receive a measurement of the distance of the lift plate from the sensor, and output an indicator describing an amount of print media in the tray based on the measurement of the distance of the lift plate from the sensor.

Abstract: An example assembly includes a first guide positioned in a pre-print zone area of an imaging device. A second guide rotatably is connected to the imaging device and spaced apart from the first guide to permit a print medium to traverse between the first guide and the second guide. A bearing mechanism connects the second guide to the imaging device in the pre-print zone area. An interface mechanism is operatively connected to the second guide. A bias element is positioned between the interface mechanism and the second guide to release energy upon exposing the interface mechanism to the pre-print zone area allowing rotation of the second guide away from the first guide.
