Character print quality and result
Menu setting Wheel position # Example 1 Example 2 Example 3
Fixed 4 D LIGHT
Fixed 5 E Very light
Result Use wheel A Use wheel C Make T&D08 = — 4
6. Finally, choose the estimate to use and Set the correct Print Gap:
a. Write down estimate A and estimate B. Compare them using the next chart:
Table 22.
Estimate comparison Action
If estimate B is equal to estimate A or up to 0.5 greater than
estimate A Use estimate A for Print Gap
If estimate B is greater than estimate A by more than 0.5 wheel
number Use estimate A + 0.5 for print gap
If estimate B is LESS than estimate A, the print needles are worn
down Replace printhead & repeat samples
b. Set the correct print gap using T&D08: Change the T&D08 value until the wheel goes to the Chosen wheel
position from step 6a.
c. SAVE and exit the T&Ds.
