Cleaning Cleaning the Image Scanner If the glass of the scanner gets soiled from ink or paper dust, the quality of the image data may deteriorate. Clean the glass every 6 months or every 100,000 passes. Follow these steps to clean the glass. 1 Open the scanner cover. See "Opening the Scanner Cover" on page 46 . 2 Lightly wipe the glass areas shown in the picture below with a soft, dry cloth. When the glass of the scanner is smeared with oil, grease or other unremovable substance, wipe it with a cloth lightly dipped in alcohol. After that, wipe off all remaining alcohol. Do not use synthetic detergent, benzine, water, or other liquid for cleaning. Doing so may result in a stain.
Never apply any liquid directly to the glass of the scanner. Be careful not to spill liquid into the scanner mechanism or electronic components. This could permanently damage the mechanism and circuitry. CAUTION 3 Close the scanner cover firmly until it clicks in place. It is recommended to clean the image scanner once per week or once every 2,000 checks for good reading results. 54
