CHAPTER III. CARE AND MAINTENANCE
Your scanner is designed to be maintenance-free. However, routine care
and maintenance can keep your scanner working smoothly.
Cleaning the Scanner
Paper powder, dust, ink and toner from paper being scanned may make
the inner document feeder dirty, which leads to poor image quality or
document-feeding errors. How often you clean your scanner depends on
the type of paper and number of pages being scanned.
Perform the following procedures to clean the scanner surface and the ADF
unit. Gently wipe locations described herein. Do not rub too hard.
Warning
 Before cleaning the scanner, turn off
the scanner and disconnect the power
cable and USB cable, and wait a few
minutes for the glass and/or the inner
ADF to cool to ambient temperature.
 Wash your hands with soap and water
after cleaning the scanner.
Cleaning Materials
Have the following cleaning materials ready to clean the scanner:
 soft, dry, lint-free cloth (or a cotton swab)
 non-abrasive cleaner—Isopropyl alcohol (95%). DO NOT use water.
Attention
 Alternatively you can use glass
cleaner or neutral detergent to clean
the scanner glass.
 DO NOT use either products to clean
the ADF feed roller or pad module.
Use of other cleaning materials could damage your scanner.
