Topic
To adjust paper width, the KNOB SIZE is rotated. In a rare case, the BELT linked to KNOB skews and the convex of
the inside of the BELT contacts the FRAME L ASSY. Then, some noise is generated when driving or the rotation of
the KNOB will be heavy. Therefore, the SPACER (No.1) was added so that the edge of the BELT can contact the
SPACER when it skews.
