with streaks, smears, and other marks that transfer from the glass area while scanning documents.
Use a lint-free cloth lightly dampened with Xerox Anti-Static or another suitable non-abrasive glass 
cleaner to clean the document glass and the CVT glass to its left.
Use a lint-free cloth, Xerox Cleaning Fluid or Xerox Film Remover to clean the under side of the 
document cover and the document feeder.
