Abstract
In a tandem media supply, two vertical stacks of media sheets are stored. The first stack is positioned on a lift plate that rises as top sheets are removed from the stack of media. When the first stack is exhausted, the second stack is moved by an actuator towards a position where the lift plate was loaded with the first stack of media sheets. Movement of the second stack displaces a biased gate to decouple the lift plate from a drive member that elevated the lift plate. The lift plate drops under the effect of gravity to a position where the second stack of media sheets moves onto the lift plate. Once the second stack is on the lift plate, a biasing force returns the biased gate to a position that enables the drive member to elevate the lift plate.
