3.17.2 Adjusting the 9
th
station slider for CP-742/743(M)E
1. Remove shaft G or O to gain access to the 9
th
station slider.
2. Turn the cam to 0 degrees and turn the placing solenoid valve ON. (Y035)
3. Adjust the slider height, so the leading edge top surface between the cylindrical cam and slider is
smooth to the touch. (See Fig. 51) Or use a dial gauge as indicated in Fig. 52.

Place a dial gauge against
section A and set the gauge to
zero. Measure the height to
section B (in the Y-direction).
Tolerance: ±0.03 mm
Target: ±0.01 mm

4. Adjust the height using the 9
th
station adjustment rod in the cam box. After completion, rotate the
index and return to check the position. If OK, then make sure the lock nut is tight on the rod.
3.18 Reattaching the Shaft Assembly
When the slider height adjustment has been completed, reattach the shaft in the reverse order
removed.
1. Tighten the retainer installation bolts (M4 x 12 ) using a torque wrench:
Torque value: 1.96N.m (20Kgf/cm)
2. Using the bar jig (at station 9), re-install the shaft assembly (with the cam at 180 degrees) and
align the holder and clutch so the alignment jig inserts smoothly between the holder and the
clutch. (there should be NO resistance) It is important for all shafts and clutches to be aligned
properly in order to avoid problems later on.

3.19 Placing Height Z0 Calibration
Carry out the procedure listed below to set the Placing Origin height. (Z0)
NOTE: Calibrate only after adjusting the ST9
slider height.
1. Turn the ST9 solenoid valve ON at 0 degrees.

2. After the Z- axis adjustment is completed, clamp the jig plate (fig. 53) in the middle of the table,
and install the nozzle jig in the A holder.
3. Manually move the jig under the ST9, placing point.
4. Set the cam angle at 195 degrees to lower the nozzle jig. Manually raise the Z-axis so that the
nozzle jig is in contact with a feeler gauge jig (-0.3mm). The Z-axis servo counter at this time is
Z0.
Target: CP-732/733E (5000 +/-500 pulses)
Target: CP-742/743(M)E (6000 +/-500 pulses)
5. Calibrate “Z0” on the reference side, adjustable side and center of the jig plate. The
deviation between each measuring point should be within 50 pulses
of each other.
6. Enter the average value (of the three measurement points) to the Calibration Data as
follows:
Press: [Maintenance] → [Calibration] → [Placing Reference] → [Z0] → [Set]

IMPORTANT!!
The placing height calibration is critically
important to ensuring stable placement.
If not adjusted correctly, damage to
components may occur (due to shock
from nozzle) or placing accuracy will not
be at optimum levels. Be sure to use
care when making adjustments in this
area.

7. Alternatively, clamp the XC/YC calibration plate in the center of the table. Raise the Z-axis until
the dial gauge deflects 0.3mm. The Calibration Data value will be the servo pulse count with the
gauge deflected 0.3, plus 1050 (thickness of the jig plate). This procedure works well resulting
in basically the same value as obtained using the procedure in steps 1 to 6.

Chapter 4 Station Adjustment
4.1 Shaft Assembly Adjustment
1. With the cam at 0 degrees, turn the 9
th
station placing solenoid valve OFF. (Y034)
2. Make sure that there is a nozzle holder on shaft A.
3. Check the alignment of the holder and clutch at 195 degrees. Use the jig indicated in
Fig.1.
Jig No. CP-732/733E: DCPJ0431
CP-742/743(M)E: DGPJ0020.

4. If the holder and clutch are not aligned correctly, use a 7mm spanner at position A in the
diagram below; and a 2.5mm L-wrench at position B, to loosen the shaft assembly and realign
them.

5. When the clutch and holder on the shaft assembly are correctly aligned, there should be no
resistance with the jig.
6. Finally, in preparation for the adjustments that follow, remove the holder from shaft A.
