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 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

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

click
Scan Settings
, and then click

.
