8. CARE AND MAINTENANCE
8.1 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.
3. Wipe the pad in the direction from top to bottom. Be careful not
to hook the pick springs.
