[Note]

If the drum separation pawl is brought into contact with the
drum at a same position for 160K life period, the drum may
be worn down remarkably. In order to prevent against this,
change the installing position of the separation pawl at 80K
maintenance.

<Procedure>

When replacing the drum separation pawl unit, change the
marking position (which is fit with the positioning rib) from A

→

 B 

→

 A ... at every 80K to change the contact position

between the separation pawl and the drum.
