11. The test completed successfully if the display advances to the next test number.
12. T&D12 determines the number of motor steps to move from “full open” gap to the “1-part paper=0.1mm” print
gap position. Calibrate the printer to the minimum allowed: 1-part paper=0.1 mm.
T&D12 - AFTA Calibrate Test
You must complete this test to:
v
Calibrate the microcode for the printhead
- and -
