6. PREVENTIVE MAINTENANCE
6.1 Cleaning
This S900 is designed to be maintenance free. However, it is suggested to perform preventive
maintenance in the shorter term either every 6 months or every 60,000 sheets scanning to ensure a
consistently optimum performance.
6.1 CLEANING THE DOCUMENT GLASS
There are times when the document cover and document glass are contaminated with ink, toner particles,
or paper coatings. In this case, the S900 will have to be cleaned frequently to ensure the best
performance.
Follow the cleaning procedure as below:
(1) Open the document cover.
(2) Dip a clean cloth with non-corrosive solvent like alcohol (purity above 99.5%).
(3) Wipe the document cover and the document glass gently as shown the following figure. Continue
until the entire document cover and document glass is cleaned and observed that no cleanser
remains on the surface.
(4)
Close the document cover. Your S900 is now ready for use.
