2.5 B-Cam Scale Angle Check (Timing Reference Point)
1. Set a dial indicator on the cam lever of the waste tape cutter (B-axis). Check that the
maximum diameter (low point) of the cam is set to: 194 degrees: CP-732/733E, (190
degrees: CP-742/743(M)E)

2. When measuring with the dial gauge, find the center point and move the cam lever
0.01mm as indicated above. If the setting is balanced, the readings should be as
indicated. However, if not, move the angle scale so the readings are within range.
IMPORTANT!
The Cam B axis scale is the reference point for all timing within the Cam Box. Be sure
this adjustment is carried out correctly. Otherwise, the machine timing will be adversely
affected.

2.6 Cam-axis Synchronization (Using B-axis Scale)
1. Set a dial gauge against the nozzle holder. When the nozzle index stops, the cam angle
should be between 140 and 144 degrees. When starting to move, the cam angle should be
between 234 and 238 degrees.

2. Set a dial indicator on the theta index helical gear. When the theta index stops, the cam
angle should be between 70 and 72 degrees. When starting to move, the cam angle should
be between 296 and 298 degrees.

3. Set a dial indicator on the RQ cam lever (Station 10). Make sure that when the cam lever is
at the low point, the cam axis is between 94 and 274 degrees.

4. After checking the above, ensure the A-axis scale matches the B-axis reference scale.
Notes:
1. In all cases above, the maximum difference between the stopping and starting points
should be within +/- 1 degree.
Example: (fig. 4 above) If the nozzle index stops at 142 degrees, it should begin moving at
236 +/- 1 degree.
2. The exact timing of movement varies a little from machine to machine. (but still within
tolerance). The main point is to ensure that the stopping and starting points are balanced.

2.7 Helical Gear Backlash Check
1. Check the backlash of the large helical gear using a dial indicator with shafts A, E, I,
and M at station 9. (Cam at 180 degrees)
2. The backlash between the two helical gears should be within 0.02 to 0.06mm.

Theta Index Unit
3. The backlash may be adjusted by moving the theta index unit to the right or left.
2.8 Cam Lever Stopper Adjustment
1. Turn the machine power OFF.
2. At 0 degrees, set the gap between the cam follower and cam as indicated below for
Station 1 Nozzle up/down, Station 1 tape feed, Station 9 up/down and Station 14
nozzle change.
3. Manually, turn each station’s solenoid valve OFF at zero degrees. (fig. 10)
The solenoid valve should be OFF when setting the dial gauge, and ON when making
adjustments. For the valve buttons: [Green = ON] [Orange = Off]
4. Set a dial gauge on the cam lever at the locations shown in fig 8 and measure the
clearance according to the table below:
