Your business's flatbed scanner turns paper documents, such as letters and photos, into digital files. For an image to scan clearly, without streaks, smudges or other defects, the scanner's glass must be clean. Even if the glass appears clean, the scanner will magnify small pieces of dust, and they may cause specks and streaks on the scanned document. You don't need any special equipment to clean your scanner, and removing dust ensures that your documents scan correctly every time.

Step 1

Power off the scanner and disconnect the power cable and the USB cable.

Step 2

Dampen a lint-free cloth with ammonia-free glass cleaner. Do not spray the glass cleaner directly on the glass. If you do so, the cleaner may leak into the scanner and cause damage.

Step 3

Lift up the scanner lid and wipe the glass with the cloth to remove streaks and dust. Wipe the glass from the top of the scanner to the bottom, and move the cloth in one direction to avoid leaving more streaks. Apply more glass cleaner to the cloth, if necessary.

Step 4

Allow the glass to dry, or wipe it dry with a clean cloth or paper towel.

Step 5

Close the scanner lid and reconnect the power cable and the USB cable. Turn on the scanner.
