MP tray media-presence detection
The DC controller detects whether paper is loaded in the MP tray by monitoring the MP tray media out
sensor. The MP tray media-presence detection is not performed during Sleep mode. The DC controller
determines a media-absence and notifies the formatter when the MP tray media out sensor does not
detect any paper.
