Clean the scanning glass ( the top and bottom) and rollers. When cleaning off dirt with adhesive properties such as glue and correction fluid, try applying a little pressure when wiping the places corresponding to where the lines appear. If the problem is not solved after cleaning, the inside of the glass may be scratched.

1. Open the feed tray.
   
   
   
2. Open the feeder cover.
   
   
   
3. Remove any dirt from the scanning glass, separation pad and rollers inside the scanner (parts shown in the figure).
   
   Use a clean dry cloth to wipe off any dirt on the scanning glass.
   
   Wipe off any dirt on the rollers with a cloth that has been dampened with water, and then wipe the rollers with a clean soft dry cloth.
   
   Remove the feeding rollers before cleaning them.
