e. Find print head gap that begins to give DARK print.
Note: DARK characters are bold and black. Light characters are grayer. Very light characters are
even grayer and begin having missing dots.
f. Referring to Table 19, if you see Examples 1, 2, or 3 note the Wheel position number where DARK
begins. If you see Example 4, you will need to use T&D10—AFTA calibrate test to decrease the gap
by the value by −4. This will make the samples look like Examples 1, 2, or 3.

Gap B → The Wheel position where DARK characters begin is Print Head Gap B.
Step 3. Determine the Wheel Position resulting in the correct print head gap.
Determine the Wheel position that will provide the best print quality while ensuring reliable paper feeding.
Gap A versus Gap B Comparison
If Gap B is equal to Gap A or up to 0.5 Wheel number greater
