Cleaning the Glass Display/Scanner Aperture
Note: These instructions are for components made of glass. If there is a removable protective
film sheet on the display screen, remove the film sheet before cleaning the screen.
Keep fingers and rough or sharp objects away from the scan aperture and display. If the glass
becomes soiled or smudged, clean only with a standard household cleaner such as Windex®
without vinegar or use Isopropyl Alcohol. Do not use paper towels or harsh-chemical-based
cleaning fluids since they may result in damage to the glass surface. Use a clean, damp, lint-free
cloth. Do not scrub optical surfaces. If possible, clean only those areas which are soiled.
Lint/particulates can be removed with clean, filtered canned air.
