How to Clean a Scanner? (by 4 users)

Typical scanner use leaves dust and fingerprints on the glass, which degrades the quality of your scans. Follow these steps to clean your scanner.
1. Gather your cleaning materials. You'll need a soft, lint-free cloth (anti-static rags are particularly good for this purpose); and Endust for Electronics, an eyeglass cleaner, or a mild, non-streak glass cleaner.
2. Check your owner's manual. If the manufacturer has provided specific instructions, follow them.
3. Unplug the scanner.
4. Spray glass cleaner on your cloth.
5. Raise or remove the scanner lid.
6. Wipe glass until visible dust specks and grease have been removed.
7. Immediately wipe the screen dry with a dry portion of the rag or a second rag.
8. If you are not satisfied with the results, repeat the process.
9. Clean the chassis with the same fluid or with any other product suitable for cleaning plastic. (Some manufacturers recommend mild detergent dissolved in water.)
10. Clean under the glass (the underside of the glass and inside of the chassis) only if recommended by the manufacturer. Some manufacturers recommend carefully cleaning the mirror with a camel-hair brush or compressed air; most manufacturers recommend professional service for interior cleaning.
