Notes on reassembling:
• Distinguish the Ribbon Tension Spring R (used here) from the Ribbon Tension Spring F (used in
3-5-8 “Ribbon Tension Shaft F SA”). They look like the same, but the number of turns differs.
18 turns (Spring F, Ribbon Tension)
20 turns (Spring R, Ribbon Tension)
• When assembling the Tension Base Adjust Cam, adjust its position as shown in the figure to set
it at the mechanical center. Then, perform adjustment according to 3.6.2-(2-1) “Tension base
adjust cam position adjustment (For service personnel)” on page 3-
47.
• When assembling the tension adjust screw (PH, M1.7x4), perform 3-6-3 “Ribbon Tension
