Frequently asked questions
This section provides information on some common questions, and provides
answers to those questions as well.
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 the Scan Picture ( ) and the Scan Slides or Negatives ( ) buttons
on the front of the scanner at the same time while reconnecting the power
cable to the scanner.
The carriage in the scanner should move forward. The scanner lamp should
blink six times. Then the scanner carriage should move backwards.
4 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 problems continue, see “Customer support” on page 8.
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).
