Carrier Return Latch Actuating Arm Adjusting Screw
(latch height) - With the carrier return cam latched
in the rest position, adjust the screw so that the car-
rier return latch will pass under the cam follower by
.00111 to .010

(Fig. 142).
CAUTION:
Any change in the carrier return latch
height directly affects the front to rear position of
the latch {with respect to the cam follower} when
the machine is at rest. See adjustment #4 in the
Operational Control Section.
NOTE:
On a limited number of printers equipped
with the early style carrier return mechanism, a
carrier return latch actuating arm was lJ:>ed that did
not have a flat surface machined on the left end of
its pivot pin. These early·production latch actuat-
ing arms should be replaced before attempting to
make the carrier return adjustments. The flat sur-
face machined on the left end of the pin is required
to establish the proper radiai position of the carrier"
return lever on the pin (with respect to the latch
actuating arm)
I
and insures that the carrier return
lever cannot slip on the pin.
