5. Maintenance
5.1 Cleaning the Copyboard Glass
Your scanner is designed to be maintenance free. However, it
still needs to be cleaned from time to time to ensure optimum
image quality and performance.
The scanner document glass may be contaminated with ink, toner
particles or paper coatings. As a result, the scanner needs to be
cleaned occasionally particularly if the scanned image looks
smeared.
The cleaning procedures (See Figure 5-1)
1) Open the document cover.
2) Soak a cotton swab with some isopropyl alcohol. (95%).
3) Wipe the copyboard glass by moving the swab from side to
side. Repeat this step until the whole copyboard glass is
cleaned.
4) Close the document cover. Your scanner is now ready for
use.
