4.1 Feed roller pressure adjustment (LU-404 only)
Conduct the feed roller pressure adjustment when there occurs a no feed condition while in the paper feed.

• Adjusting the feed roller pressure changes the pick-up release amount. So after completion of
adjustment, be sure to check the pick-up release amount.
• Be sure to purchase the paper feed assist plate (P/N: 13FG4062*) separately since it is supplemen-
tal part.
