care and maintenance
This section presents information about how to care for and maintain the scanner.
Occasional cleaning of your scanner helps ensure optimal performance. The
amount of care necessary depends upon several factors, including the amount
of use, the type of media that is fed through the ADF, and the environment. You
should perform routine cleaning as necessary.
Routine cleaning and maintenance should include cleaning the scanner glass,
the TMA, and the ADF.
Caution! Avoid placing items that have sharp edges in the
scanner. Doing so can damage the scanner. Before placing an
item on the scanner glass, make sure that the item does not contain
wet glue, correction fluid, or other substances that can be
transferred to the glass.

1 Disconnect the universal serial bus (USB) cable and power cable from the
scanner.
2 Clean the glass by using a soft, lint-free cloth that has been sprayed with a
mild glass cleaner, and dry the glass with a dry, soft, lint-free cloth.
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.
3 When you have finished, reconnect the USB cable and power cable to the
scanner.

glass, visit www.hp.com/support.
