Frequently asked questions
This section contains answers to frequently asked questions.
How do I test my scanner hardware?
1 Ensure that the TMA cable on the scanner lid is connected to the back of the
scanner.
2 Ensure that the scanner is not connected to the computer.
3 Reset the scanner. See Reset the scanner.
4 Disconnect the USB cable and power cable from the scanner.
5 Ensure that the scanner power cable is still connected to the power source.
6 Press and hold the Scan(
) and Copy buttons ( ) on the scanner at the
same time while reconnecting the power cable to the scanner.
The TMA should turn on for three seconds and then turn off. After the TMA
turns off, the carriage in the scanner should move forward and backward, and
the scanner lamp should turn on. The scanner lamp should flash six times
while the carriage is still in motion.
7 To end the test, disconnect the power cable.
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.
2 Select Scan Settings & Preferences.
3 Select Scan Preferences.
4 Click the Quality vs. Speed tab.
5 Turn off Extended lamp 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 issues continue, see Customer support.
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).
