3-6-2. Ribbon Slant Elimination Adjustment
There are two kinds of ribbon slant elimination adjustments: for user and service personnel.
1) For User
• Adjustment with the Ribbon Left-Right Balance Adjustment Knobs (Front/Rear)
2) For Service Personnel
• Tension Base Adjust Cam position adjustment:
• Ribbon guide position adjustment (The ribbon guide is a part of Head SA.)
Note : The general procedure how to remove ribbon wrinkles is explained on page 3-50 . Refer to
“Removing Ribbon Wrinkles” on that page.
(1) Ribbon slant elimination adjustment (For user)
As you turn the Ribbon Left-Right Balance Adjustment Knobs (Front/Rear), the knob side (right
side) of the Ribbon Tension Shaft F SA moves back and forth with the eccentric mechanism,
and also, the knob side (right side) of the Ribbon Tension Shaft R SA 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.
