Care and maintenance
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 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 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.
Note For instructions about how to clean the underside of the scanner glass,
visit www.hp.com/support.
Clean the transparent materials adapter (TMA)
Clean the TMA with a dry, soft, lint-free cloth. If necessary, lightly spray the cloth with
glass cleaner and wipe the TMA.
Clean and maintain the automatic document feeder (ADF)
The ADF requires periodic cleaning depending on the amount of use and the type of
media that is fed through it. Use an HP ADF cleaning cloth to clean the ADF when
vertical streaks appear in images scanned by the ADF, when media running through
the ADF is dusty or dirty, or when the environment is dusty. If you use the ADF
