Abstract
In a media tray, a mid-tray sensor is located relatively equally distant between the tray front and the tray back. This allows the tray to be free of a divider between the front and reserve stack areas. After the user closes the tandem tray, an elevator plate lifts media in the lead stack location and a slider moves in a forward direction toward the tray front based on the front media sensor not detecting media in the front stack area, or whenever the mid-tray sensor detects media located between the front stack area and the reserve stack area. An alarm is produced when the front media sensor does not detect any media, or when the slider is unable to move when it should be able to move (forward into the front stack area, back through the reserve stack area, etc.).
