AUTOMATIC FEED SEQUENCE
With no optional feed trays installed, the Autotray function in the Print
Menu is set by default to OFF and the Tray sequence function is set to
DOWN. Ensure that the Autotray function is set to ON (default) when you
have either or both optional feed trays installed. In this way, if a tray runs
out of paper, automatic feed will take place in the order Tray 1, Tray 2 (if
installed), provided that these trays are set up for identical media.
