■ in order to maintain the quality of your scanned images, regularly clean the glass plate.

    ■ before cleaning, switch off the scanner by unplugging the power cord.

    ■ use a damp cloth and a mild detergent or alcohol to clean the surface of the glass plate.

    ■ when you use sprays directly onto the glass plate, avoid the seams around the glass, as this may cause the liquid to penetrate and contaminate the mirrors and lenses inside the scanner. do not use detergent on the plastic parts of your scanner.

    ■ especially the cleaning of the calibration slits in the holders is important. keep this area dustand dirt-free.
