5. Maintenance
5.1 Cleaning the ADF
Your scanner is designed to be maintenance free. However, it still
needs to be 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 will need to be cleaned
frequently in case:
1) Documents do not feed smoothly or easily;
2) Several documents feed at the same time.
The cleaning procedures
1) Soak a cotton swab with some isopropyl alcohol. (95%).
2) Open the scanner front door and wipe the upper feeding roller by
moving the swab from side to side. Rotate the roller forward
with your finger and repeat the cleaning steps above until the
entire roller is cleaned. Be careful not to damage the pick
springs.
3) Wipe the pad in one direction from top to bottom or the other
way around. Be careful not to damage the pick springs.
4) Close the scanner front door. Your scanner is now ready for use.
