6.1 Cleaning the ADF
Your scanner is designed to be maintenance-free.
However, it still needs to be cleaned occasionally to ensure
optimum image quality and performance.
The scanner parts may be contaminated with ink, toner
particles or paper coatings. As a result, the scanner needs to
be cleaned occasionally particularly in the following cases:
1. Documents do not feed smoothly or easily;
2. Several documents feed at one time.
The cleaning procedures
1. Wet a cotton swab with some isopropyl alcohol. (95%)
2. Open the ADF unit as shown below and wipe the upper
feeding roller by moving the swab from side to side.
Rotate the roller forward with your finger and repeat the
above cleaning procedures until the entire roller is cleaned.
Be careful not to snag or damage the pick springs.
