4.7.2.5 Card Lever
With pin bail arm against its stop, position card lever to
clear pin bail by 0.005 inch to 0.010 inch.
4.7.3 Pin-Sensing Unit Removal and Replacement
1. Remove eject mechanism from top of pin-sensing unit.
Removerelease pin that operates eject mechanism.
2. Remove the three screws holding eject front rail, the two
nuts beneath this rail, and the two nuts holding stacker
plate to stacker assembly near stacker switch. The plate
can now be removed. (When reassembling, check adjust-
ment of traveling card guide before tightening nuts.)
3. Disconnect pin bail drive link at its coupling screws
(Figure 4-29) through hole in rear of punch bed. Do not
remove spring from link-to-drive-unit rear frame.
4. Remove the screw holding the sensing-pin cable clamp.
5. Remove the two screws in top of pin-sensing unit and
lift out unit from top ofbase.
6. With long-nose pliers, pull out common wire to sensing
contact strip; then slip off connections to individual
terminals. Note that cable is fanned out so that it can be
easily reinstalled.
7. Reinstall unit in machine with punch index at 345
degrees. Extend pin bail link to bring pin bail arm up
against the stop.
CAUTION
Do not overextend pin bail link because punch drive
can be damaged.
8. Check to see that PS makes after and breaks before pin
contacts. Be careful that plastic dust cover does not bind
the 9-sensing contact.
4.7.4 Sensing Pin Removal
1. Remove pin-sensing unit from machine.
2. Trip card lever and place pin-sensing unit upside down.
3. Removeplastic dust cover for sensing pin contacts.
4. Remove the two screws holding contact assembly to
frame and lift it off. This exposes operating ends of
sensing pins. Use care to avoid moving contact bail
because it is possible to lift all sensing pins out of the
separator; considerable time is needed to replace them.
4.8 EJECT UNIT
4.8.1 Eject Unit Adjustments
4.8.1.1 Pressure Roll Registration
Adjust pressure roll lever shaft to align pressure roll with
feed roll and cause proper feeding through read station
(4.5.11.2 and 4.5.12.2).

(4/69)
4.8.1.2 Pressure Roll Opening
For adjustment of pressure roll opening, see 4.5.11.2.
4.8.1.3 Throat
Add or remove shims for a throat clearance of 0.012 inch
to 0.020 inch. (See 4.7.2.2.)
4.8.1.4 Register Arm Tension
1. Tip bed to vertical position and turn CF index to 30
degrees.
2. Insert strip of card betweenrolls.
3. Form paper clip to hook under arm just inside roller,
and hook other end in hole of 10X blade.
4. Form long end of spring to require 200 to 275 grams to
free the card.
4.8.1.5 Eject Arm Tension
Use the procedure under 4.8.1.4.
4.8.1.6 Eject Card Guide
The plastic guide should clear the stacker plate by at least
0.016 inch. It can be raised by filing the eject casting
slightly or by shimmingthe right end of the guide. Forming
the plastic is unsatisfactory because, even if heat is used,
the plastic returns to original condition.
4.9 STACKER UNIT
4.9.1 Stacker Unit Adjustments
Note: Check wiring diagram for exact timings on machines
with special features such as variable card length feed.
4.9.1.1 Stacker Timing
With card feed index at O degree, time stacker with teeth
that provide the closest measurement to 4-11/16 inches
from upper cut in stacker drum to front edge of base. This
