@Olarichdom,

Welcome to the HP Forums 🙂 I would like to take a moment and thank you for using this forum, it is a great place to find answers. For you to have the best experience on the HP forum, you could also visit our HP Forums Guide for First Time Here? Learn How to Post and More. I see from your post that you are having issues with the scan quality. Don't worry we'll work together to help you find a solution.

To provide you with an accurate solution, I'll need a few more details:

Have you recently made any changes before the issue started?

Have you tried to clean the scanner glass?

Have you tried to reset the scanner?

Clean the scanner glass: 

Cleaning of the scanner glass helps ensure high-quality scans. The amount of care

needed depends upon several factors, including the amount of use and the environment.

You should perform routine cleaning as necessary.

1. Disconnect the USB cable from the scanner.

2. Clean the glass 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 to the scanner.

NOTE: For instructions about how to clean the underside of the scanner glass, visit

www.hp.com/support.

If the issue persists, I would suggest here is to reset the scanner, for more details, please check this link: HP Scanjet Scanners - Resetting the Scanner

Please let me know if this resolves the issue, or if you require further assistance!

Eagerly waiting for your response!
