HP scanjet g4010 [22/28] Buttons appear not to work

Scanner will not turn on

If the scanner will not turn on when you press the front-panel scanner buttons, check for

these possible problems:

● The scanner might have been unplugged. Check to see that the power cable has

not become disconnected from the scanner or unplugged from the power source.

● The scanner might be turned off. Check to see that the scanner power switch is in

the on position.

● Check to see that the TMA cable has not become disconnected from the scanner.

Scanner does not scan right away

If the scanner has not been used for a while, the scanner lamp might need to go through

a warm-up period before scanning can begin. If the scanner lamp needs to warm up, it

takes a moment after starting the software or pressing a scanner button for scanning to

begin.

To change the lamp warm-up setting, open the HP Solution Center, click Settings,

click Scan Settings, and then click Scan Preferences.

After each step, start a scan to see if the buttons are working. If not, proceed with the

● Restart your computer.

● The buttons might be disabled. Try the following procedure:
