1. To gain access to the wheel, remove the left side cover.
2. Verify the smooth rotation of the wheel. Hand cycle the wheel clockwise (as viewed from that end of the
printer) to a higher value, until the mechanical stop is against the frame. This is the full-open gap position.
v The travel of this rotation should equal about 10 to 11 numbers on the wheel.
v The travel through the entire range must be smooth and free of any binding as you rotate the wheel to
full-open, then to the full-close position. If you feel any binding:
a. Check the AFTA intermediate gear (gray) and the wheel (white) for damaged teeth. Replace, if
necessary.
b. Ensure the AFTA motor is not pushed upward too much against the AFTA intermediate gear. Loosen
and retighten the AFTA motor screws. This will allow the AFTA motor to fall away from the AFTA
intermediate gear.
v Check the ends of the (large) carriage shaft for correct adjustment.
– If the carriage shaft is too tight, you will notice binding at the frame.
– If the carriage shaft is too loose, you will notice clicking at the frame when you grasp the carriage shaft
and attempt to move it up and down.
