Advanced Media Control
Auto Tray Change
When an input tray runs out of paper, auto tray changing enables 
the printer to switch to another available tray that contains the 
same Media size and type.
Media Check
Controls whether or not the paper size and media type specified 
in the print job must be used to satisfy the print request. 
When both Auto Resize and Media Check are enabled, Auto 
Resize overrides Media Check in regard to paper size. 
To force a specific paper size, disable Auto Resize in the printer 
menu (under Admin Setup > Print Menu).
Express Print
To use Express Print, you must disable Media Check. You can use 
the driver to do this. 
When the printer is in Express Print mode, you can leave the default media 
settings as is in the printer, and it will assume the paper you put in the tray 
and selected in your driver is the correct size and type for the print job. 
This allows you to switch between paper sizes easily without configuring 
custom paper sizes at the printer. It is up you to load the correct 
media in the designated tray.
