care and maintenance
Occasional cleaning of your scanner helps ensure optimal performance. The
amount of care necessary depends upon several factors, including the amount
of use and the environment. You should perform routine cleaning as necessary.
Routine cleaning should include cleaning the scanner glass and the TMA.
clean the scanner glass
1 Disconnect the power cable from the scanner.
2 Open the scanner lid.
3 Clean the glass using a soft, lint-free cloth sprayed with a mild glass
cleaner.
Caution! Use only glass cleaner. Avoid abrasives, acetone,
benzene, and carbon tetrachloride, all of which can damage the
scanner glass. Avoid isopropyl alcohol because it can leave
streaks on the glass.
Do not spray the glass cleaner directly on the glass. If too much
glass cleaner is applied, the cleaner could run to the edges and
damage the scanner.
4 Dry the scanner glass using a dry, soft, lint-free cloth.
5 When finished, reconnect the power cable to the scanner.
For instructions on cleaning the underside of the scanner glass, go to
www.hp.com/support, select your country or region, navigate to the support
page for your scanner, then click the link to view information about cleaning the
underside of the glass.
clean the TMA
If you have an HP Scanjet 3670, 3690, or 3970 scanner, clean the TMA using
a dry, soft, lint-free cloth. If necessary, lightly spray the cloth with glass cleaner
and wipe the TMA.
scanner installation or setup problems
check your computer
• Ensure that your computer meets the minimum system requirements that are
listed on the scanner box.
• If you do not have enough hard-disk space, remove unnecessary files or
install the software on a different disk drive.
use a valid folder
On a Microsoft Windows computer, if you receive a message, such as
“Destination Directory Is Invalid” or “Program Folder Is Invalid,” during
installation, you may not have read/write permissions to that folder.
