v T&D08—AFTA calibrate test
v T&D12—Fanfold form printout test

Power Off Check: Perform this check if the AFTA indicator wheel (wheel), AFTA motor, gears, carriage shaft, or
platen have been removed at any time for service.
This check verifies the position of the wheel, and the manual operation of the AFTA mechanism. Use the wheel as
an indicator as you adjust the distance between the print needles and the platen. Each numeral change on the
wheel represents 0.1 mm (0.004 in.) change of AFTA gap. The numbers 0 through 6 are printed on the wheel, but
the numbers can be considered to go beyond the 6 to an implied number of 13.
