Occasional cleaning of your scanner helps ensure higher-quality scans. The amount of
care necessary depends upon several factors, including the amount of use and the
environment. You should perform routine cleaning as necessary.
For all care and maintenance procedures required for the scanner, please see the Care
and maintenance section for your scanner in the onscreen Help. In the HP Solution
Center, click
Help
, and then select the Help section for your scanner model.
Routine cleaning and maintenance should include cleaning the scanner glass and the
transparent materials adapter (TMA).
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.
Clean the scanner glass
1.
Disconnect the 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.
