The stacker is “switched on” by connecting the power cord to
the power outlet.

There is no power switch.  The power cord is the on/off
switch.

Once the power cord is connected to the power outlet, the
stacker motor drive and fan initialize.

As media leaves the printer, the lead edge of the media enters
the stacker.  A motion sensor in the stacker detects the lead
edge of the media and the fan and motor are switched on.  The
media then is fed into the stacker inclined tray.

When the motion sensor detects the trail edge of the media, the
fan and motor continue to run until the print is fed into the
inclined tray.  After the last print output is fed into the stacker
tray, the fan and motor switch off.

The Stacker 1000 is equipped with tray extensions:

These tray extensions are used for E-size (A0) and longer-size
prints.
