4–18 Adjustment Procedures
Ribbon Guide Alignment (Figure 4–9 )
1. Open the printer cover.
2. Load paper and install the ribbon. To adjust the left ribbon guide, the
ribbon should have a full spool on the right hub (1).
3. Run a shuttle and ribbon diagnostic self–test (page 3–27).
4. To adjust the left ribbon guide, momentarily short between the left
ribbon guide skid screws (2) to assure right to left motion of the ribbon.
5. Observe how the ribbon (3) is passing around the left ribbon guide (4).
It should be centered and not folding against either of the two white
nylon washers.
6. If the ribbon is not centered, loosen the retaining screws (5) just enough
so that the ribbon guide (4) can be rotated to new positions, but remains
in place once moved.
7. Rotate the ribbon guide (4) as necessary to center the ribbon (3).
8. Observe how the ribbon (3) is winding on the left spool (6). Reposition
the ribbon guide (4) as necessary to allow the ribbon to wind up without
interfering with the flange of the spool.
9. Tighten the screws (5).
10. Allow most of the ribbon to accumulate on the left spool (6). Repeat
steps 3 through 9 for the right ribbon guide (7).
