Epson LQ-800 User Manual page 45

Periodically, the inside of the cut sheet feeder should be cleaned to
get rid of dust and paper lint. First, turn the power OFF and remove
the cut sheet feeder from the printer. Then use a soft brush to clean the
inside areas. Make sure the gray rollers are kept free of dust so that the
paper feeds evenly.
If you have any problems, contact your authorized Epson dealer.
