Hint
In the User Mode, if the tray position is set to a height other than the
lowest position, then the Document Feed Tray moves up and down
when the power is turned on. In this case, the Document Feed Tray
is lowered once to the lowest position and then moves to the
configured height. When the power is turned off, the Document
Feed Tray does not move and stays at the configured height. (See
p. 18.)
