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 46.
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&D 12: Change the T&D 12 value until the Wheel goes to the Chosen
Wheel position from step 6a.
