Cleaning the scanner glass
● Clean the glass only if dirt is visible, or if you are experiencing a decrease in copy
quality (such as streaking).
● Clean the glass surface by wiping it gently with a clean, damp, lint-free cloth. Use an
ammonia-based surface cleaner to dampen the cloth.
CAUTION Do not pour or spray liquids directly onto the glass.
CAUTION Do not press hard on the glass surface. You might break the glass.

plastic sheet.
3 Clean the ADF backing and the calibration strip by wiping them with a clean, damp,
lint-free cloth. Use an ammonia-based surface cleaner to dampen the cloth.
