(1) Ribbon slant elimination adjustment
As you turn the Ribbon Left-Right Balance Adjustment Knob (Front), the knob side (right side)
of the "SA, Ribbon Tension Shaft F" moves back and forth with the eccentric mechanism. In the
same way, when you turn the Ribbon Left-Right Balance Adjustment Knob (Rear), the knob
side (right side) of the "SA, Ribbon Tension Shaft R" moves up and down. With this eccentric
mechanism, ribbon running can be adjusted.
TIP: The adjustment on the front side is more effective than that on the rear side.
