Service check and adjustment
1. Remove all paper, the ribbon cartridge, and the paper bail assembly.
2. Loosen the right side support shaft screw.
3. Measure the gap between the printhead and the platen at both ends of the platen, right and left.
The correct gap is 0.25 to 0.30 mm (0.010 to 0.012 in.) when the AFTA indicator is pointed to the middle of
sector 1.
The correct difference in the gap between the left and right ends is
≤
0.08 mm (0.003 in.).
4. Using pliers, rotate the eccentric bushing until a minimum difference between the left and right end gaps is
obtained (see Figure 7)
5. While holding the eccentric bushing with pliers to prevent it from moving, firmly tighten the right side support
shaft screw.
