Clean the scanning strips
To clean the scanning strip components, follow these steps:
1. Press the Power button to turn off the scanner, and then disconnect the USB cable and power supply
from the scanner.
2. Lift up the document feeder.
3. Clean the scanning strips with a soft, lint-free cloth that has been sprayed with a mild glass cleaner.
CAUTION: Use only glass cleaner to clean the scanning strips. Avoid cleaners that contain abrasives,
acetone, benzene, and carbon tetrachloride, all of which can damage the scanning strips. Avoid
isopropyl alcohol because it can leave streaks on the scanning strips.
Do not spray the glass cleaner directly on the scanning strips.
4. Dry the scanning strips with a dry, soft, lint-free cloth. Wipe the strips of gray, reflective material on
each strip.
5. Close the document feeder, reconnect the USB cable and power supply to the scanner, and then press
the Power button to turn on the scanner. The scanner is now ready to use.
