A.
POSITIONING OF FENCE (SEE
FIG~
5-2)
a.
Pull tab of fence (42) to the right so that the first
window of the fence is located 4.5-in. (114 mm) from
right side of left support post.
(Note that his dimension
adjusts for a nominal 5/S-inch print margin on printing
form) .
b.
Secure fence under right clamp (41) and when correct
dimension has been applied, tighten hardware (43, 45).
B.
OPTIC HEAD (NO LOCATING DIMENSION) (SEE FIG. 5-2)
1.
Set fibre optic head by loosening adjusting screws found on
top of video amplifier board (Fig. S-19/26), and place face
of head as close to fence without touching. Tighten screws.
Run optic head full length of timing fence insuring that
it
does not touch fence.
(If fence still touches optic head,
apply 0.005-in. thick shim/s (46) between clasp (40) and
left post). This is done to maintain parallelism within
0.05 mm (0.002-in.) between timing fence and left and right
support post.
