Cleaning the product
To clean the top ADF glass strip
If you are still experiencing poor copy quality, you might need to clean the top ADF
glass strip.
CAUTION
Clean this area only if you see copy defects such as streaks, and you notice dust
inside the glass strip. Cleaning this area frequently could introduce dust into the
product.
1 Open the ADF cover.
2 Locate the latch that releases the top ADF glass strip. Push the latch to the
left, and pull down to expose the inside of the glass strip.
3 Gently wipe the glass with a dry, lint-free cloth.
CAUTION
Use dry cloth only in this area. Do not use solvents, cleaners, water, or compressed
air. Doing so could severely damage the product.
4 Pull up on the latch to return the glass strip to its normal position.
5 Close the ADF cover.
