Abstract: A method for printing including receiving, by a printer, a first page image, a second page image, and a selection for enabling media type substitution. The printer identifies a preferred media type and an alternate media type, where the preferred media type and the alternate media type include a common printable area (CPA), and the first page image and the second page image are modified to match a dimension of the CPA. The printer then selects the preferred media type for printing the first page image.

The printer then selects the alternate media type in response to the message and the selection enabling media type substitution, and prints the second page image using the alternate media type.

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.).

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.
