6. To check the stroke, the cam needs to be set at a specific angle. Due to recent changes of the B-
cam assembly, the cam angle depends on the type of B-cam assembly. To identify which type,
look at the markings on the side of the B-axis counter balance lobe.
If the marking is “3 or 4”, the cam angle should be set to 141 degrees and the stroke amount
should be within 0.01 to 0.05mm. (“3 or 4” identifies the old type B-axis assembly)
If the marking is “x”, the cam angle should be 146 degrees and the stroke amount should be
within 0.01 to 0.05mm. (“X” indicates the newer type B-axis assembly)

Counter balance
CP742(M)E/732E = 141 degrees
CP743(M)E/733E = 146 degrees
Or
Check the marking on the B-cam
as indicated in step 6.
7. If not within range, loosen the two bolts of the stroke adjustment rod (item 1 in figure 15) and turn
the rod to change the stroke amount.
8. Once the stroke is set within range, lock the two bolts and recheck the stroke.
4.9.4 Nozzle Change Origin Position Calibration
1. Set a shaft at the RQ origin position and move it to station 13 at 0 degrees. (This action will align
the nozzle holder to the correct position for nozzle changing)
2. Rotate the NC motor to around zero pulses. Rotate the rotor until it is horizontal. When the rotor
is horizontal, the pulse count must be within 0 +/- 1800.
3. Turn the 14
th
Station solenoid valve ON. (Y037) and slowly rotate the cam to 141 degrees
(CP742(M)E/732E) or 146 degrees (CP743(M)E/733E) to engage the NC clutch rotor with the
nozzle holder clutch at station 14 while holding the clutch horizontal.
4. Move the cam-axis to a position where the clutch starts to engage and where the backlash
decreases for the NC clutch rotation.
5. When the lower gear is rotated in the above situation, the counter will vary due to the backlash.
Take the center value and set it as the NC Origin Position.
Note: The Calibration Data can be either plus or minus. However, make sure that the value does
not exceed +/- 1800 pulses.

1. Remove the 13
th
station reject parts brush, as this will interfere with the jigs.
2. Move the cam to 200 degrees. Install the above jigs in turn and check/adjust the alignment of
the 13
th
and 15
th
stations by sliding the “sliding jig” into the sensor holder brackets.
Caution – the jigs span two shafts so never rotate the cam when they are in place.

3. Once alignment is achieved, put the fiber sensors to their forward limit and lock the set screw for
each sensor.
4. Put a holder on shaft A and align it at the 10th station RQ original position.
5. Set the six sensor amplifiers to L-ON.
6. Set the mode switch of the six sensor amplifiers to SET.
7. Set the nozzle holder to the number 2 nozzle.
8. Move the nozzle holder on shaft A to the 13
th
station and 15
th
station in turn. For each station
ensure that the cam angle is at 200 degrees and the nozzle holder in place, then press the
tuning button once.
9. Next, set the nozzle holder to the number 6 nozzle.
10. Move the nozzle holder on shaft A to the 13
th
station and 15
th
station in turn. For each station
ensure that the cam is at 200 degrees and the nozzle holder in place, then press the tuning
button one more time.
11. Finally, set the sensor amplifiers from SET to RUN.

12. Check that the sensors react correctly when the nozzle holder is set to the positions shown in
the following table:

4.11 Station 1 Tape Feed Adjustment
1. Set the cam angle to 0 degrees, turn the station 1 tape feed
solenoid valve ON. (Y033)
2. Move the jig to the parts pick-up position. Adjust the
clearance between the roller and the lever to 0.5mm.
To adjust loosen bolt “A” in the cam box, (figure 22) and
then use a small spanner to adjust the rod up or down.
