6 Adjust the gap between the feeding roller and the separation roller to optimum
width.
1. While one sheet remains in place between the rollers, continuously attempt
to slide the second sheet (in front of the remaining sheet) to the right, back
through the roller gap.
2. Slowly turn the paper thickness adjustment dial clockwise (right) just until
the second sheet stops feeding into the gap.
IMPORTANT
Turning the adjustment dial clockwise too much may damage the rollers.
