(C) in the direction indicated by the arrow, then tighten screws (A) and (B) at the position where the
pressure roller contacts the sliding surface of the rear X rail. (Repeat this same procedure for the right

Confirm that the rollers remain in contact with the sliding surface throughout their entire stroke, the
sound made by the rollers turning is constantly the same, and the rollers slide smoothly.
