6.8.4 EXIT PAWL DRIVE MECHANISM

• During printing, the distance between the exit pawl [A] and the drum is very small,

to prevent paper wrap jams. However, when the master clamper [B] approaches

the exit pawl (as the drum turns), the pawl has to be moved away from the drum

to prevent it from being damaged by the master clamper. This is controlled by the

front drum flange [C], which is cam-shaped, and the cam follower [E] on the exit

pawl shaft.

• When the cam follower is not pushed out by the drum flange, the exit pawl

closely approaches the drum surface, due to the tension from a spring [G].

• As the master clamper approaches the exit pawl, the high point of the drum

flange cam [C] moves into contact with the cam follower [E] pushing it down. This

moves the cam follower arm [F] downwards. The pawl shaft turns clockwise to

move the pawl away from the drum.
