HP 4370 manual Care and maintenance, Clean the scanner glass

2 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 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 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.
