5. Maintenance
5.1 Cleaning the ADF
Your scanner is designed to be maintenance free. However, it
still needs to be cleaned (especially, the pad and the feeding
roller) 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 (See Figure 5-1)
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 and the same direction, top down or
bottom up. Be careful not to damage the pick springs.
4) Wipe where the window glass is contaminated, which is
manifested by the constant appearance of a vertical line on
some specific part of the scanned image. (See Figure 5-2)
