Tray 2 or tray 3 sensing

Tray 2 or tray 3 sensing

Expanded sensing
The printer stops the first five pages fed from each paper tray to sense the type and averages the five results.
The printer assumes that the sixth and all subsequent pages are of the same media type, until the printer is turned off or goes into sleep mode, or until the tray is opened.
Transparency only (default)
The printer does not stop any pages for sensing but distinguishes between transparencies (Transparency mode) and paper (Normal mode).
This is the fastest mode and is useful for high-volume printing in Normal mode.
