When the device is
connected to a grounded
power source, the control

the firmware is done
loading, Scanner bulb

the control panel, and the
scan head moves back
and forth for 10-15
seconds. If you lift the
scanner lid, you will see
that the scanner bulb is lit.
Near the end of this time,
the automatic document
feeder (ADF) motor turns
on for about two seconds.
