4.11.3 EXIT PAWL ADJUSTMENT
Ensures that the exit pawls can move out of the way of the drum master clamper while the drum is
rotating.
Timing Adjustment
 When releasing the stoppers from the brackets, note that the press roller goes up quickly.
1. Turn the drum manually until the recess in the drum drive gear meets the positioning hole[A]
in the bracket, as shown.
2. Release the stopper at the operation side [B] from the pressure arm [C].
 Slide the stopper [B] to the left, and then lift the pressure arm [C].
3. Loosen screws [D] and [E]. Then measure the gap between the cam follower and cam face
(front drum flange). It should be 0 to 0.5 mm. Then re-tighten the two screws while pushing
the cam follower against the cam face.
4. Lock the stopper on the operation side with the lock bracket to keep the press roller in its
correct position.
5. Do the clearance adjustment (see the next page).
