Clean the paper feed path if white spots appear because of paper dust sticking to the paper, or if paper misfeeding or double feeding occurs.
Guide Board
Wipe the guide board with a well-wrung-out damp cloth. To reach the inmost recesses, the cloth should be the size of your palm.
Paper Feed Roller
Wipe the entire surface of the paper feed roller lengthwise with a well-wrung-out damp cloth, and then with a dry, unused, lint-free cloth until no moisture remains.
