1. Turn the drum manually until the recess in the drum drive gear meets the
positioning hole [A] in the bracket, as shown.
2. Loosen screw [B] then screw [C] in that order (do not remove them). Make sure
that the bracket [D] becomes free from engagement and the cam follower [E]
contacts the drum flange.
3. Measure the gap [F] between the cam follower and cam face (front drum
flange). It should be 0 to 0.5 mm.
4. If the gap is not correct, loosen the two screws securing the cam follower
bracket [G].
5. Re-tighten the two screws while pushing the cam follower against the cam face.
Make sure that the gap [F] is 0 or less than 0.5 mm.
NOTE: Do not push the cam followers too strongly against the cam.
6. Re-position the bracket [D] and tighten the screws [B] and [C].
