frequently asked questions
how do I test my scanner hardware if I think there may be a problem?
1 Disconnect the USB cable and power cable from the scanner.
2 Ensure that the scanner power cable is still connected to the power source.
3 Press S
CAN () and COPY ( ) on the scanner at the same time while
reconnecting the power cable to the scanner.
The carriage in the scanner should move forward and backward, and the
lamp should turn on.
4 To end the test, disconnect the power cable.
If the scanner lamp does not turn on or the carriage does not move, a problem
exists with the scanner hardware. See product support on page 20.
how do I turn off the lamp?
The scanner lamp should time out and turn off automatically after a period of
inactivity (about 14 minutes). If it does not turn off automatically, do the
following:
1 From the HP Director, click Settings, and click Scan Preferences.
2 From the Quality vs. Speed tab, turn off Extend lamp timeout to turn the
scanner lamp off after 14 minutes of inactivity. If this option is on, the
scanner lamp turns off after 1 hour of inactivity.
If the scanner lamp problems continue, see product support on page 20.
how do I turn off the scanner?
Normally you do not need to turn off the scanner because after a period of
inactivity (about 14 minutes), the scanner reduces to a low-power mode.
If you need to turn off the scanner completely, disconnect it from the power source
(electrical outlet or surge protector).
