seconds. When the firmware
is done loading, Scanner
bulb warming up might
appear on the control-panel
display, 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.
