Care and maintenance

English

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.

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
