4-5 CAM GEARS
The mounting position relationship among the three cam gears
(cam gear F, cam gear R and relay gear) is special. Therefore, their
installation should be performed in the following order.
1. Move pinch roller actuating lever F and head base assembly as
shown by the arrows.
2. Mount cam gear F so that its indicated hole (*) lines up with
the hole on the transport chassis. Then relax the above-moved
two parts moved in step1.
3. Mount the other two gears by lining up their markers as shown.
Note: When mounting cam gear R, pinch roller actuating lever
R should be moved in the direction of the arrow.
