Checking the HeightITilt
(When a Malfunction
Occurs)
1) Check the height of the finisher and the host ma-
chine. Place a ruler on the buffer pass unit as shown
and check to see if it is as indicated on the right side
of the finisher (falling between the top and bottom
index lines). Check the height at both front [I] and
rear [2] by referring to the two sets of index lines;
be sure that the discrepancy in height is 1.5 mm or
less.
2) Check the tilt of the finisher and the host machine.
Check to see that the gap between the top edges of
the finisher top cover and the host machine delivery
cover is 1 1.7*2 mm or less of the Finisher-AEl and
3 +I-1.5 mm or less for the Saddle Finisher-AE2.
Take measurements at two locations (front and
rear), making sure that the discrepancy at front and
rear is 1.5 mm or less. Moreover, when looking
from the front, the gap between the finisher and the
host machine must run in parallel lines.
3) If you need to adjust the heighthilt, see "Adjusting
the HeightITilt."
