6. To set the travel limits (Min Limit D1) and (Max Limit D2) follow the procedure below:
a. Zero set both device tables.
b. Manually move D1 toward D2 (D2 is at 0 pulses) until the interference prevention sensor
triggers. Move D1 back 117 pulses (Min Limit Pos. D1) and enter the pulse count at the host
PC.
c. Position D1 to 0 pulses, move D2 toward D1 until the interference prevention sensor triggers.
Move D2 back 117 pulses (Max Limit Pos. D2) and enter the pulse count at the host PC.

3.16 D-axis Pallet Flatness Measurement
1. Flatness of the top plates on the pallets is important to maintain consistent pick up. Set up two dial
gauges as pictured and indicate the top surface of the feeder plate at the positions illustrated in
Fig.34. (Tolerance: within 0.1mm)
2. If the flatness measurement is out of tolerance, contact Fuji for further instructions.

3. Set a dial gauge and block on the machine base and check the flatness from A to B.
(Tolerance: within 0.05mm)
3.17 Cam Box Positioning Check
1. Attach the positioning jig onto the A Shaft and turn the Pick-up valve ON.
2. Position the A shaft at station 1 and set the cam to 200 degrees.
3. Install the cam box alignment jig on the D1 table.
(Tolerance: 0 to + 0.05mm)
4. Check the cam box position at slots 3 & 68 of D1 & D2
3.18 Pick up Position Calibration
1. Attach the positioning jig onto the A Shaft. (Jig No.:ADCPJ8130)
2. Set the “Pick up Position” jig on the D1/D2 table at slot No.1. (Jig No.:Z9913AWPJ9330)
3. Turn the Pick-up valve ON and set the cam to 170 degrees at Station 1.
4. Balance the dial gauge on both sides of the positioning jig in the X-direction.
When the gauge is balanced on each side, this becomes pick up position D1/D2.
5. When balanced, enter the pulse count into the proper at the host PC.

3.19 Shaft Measurement Check
The following procedure explains how to check various items on the nozzle shafts. These
measurements are required when carrying out adjustments in Chapter 5.
1. Set the Cam angle to 0 degrees.
2. Turn the 11
th
station place solenoid ON.
3. Using shaft A as the reference 0, measure the height of the shaft
flange (1) for all the shafts A to T. Measure with the cam at 200
degrees. Push down on the flange slightly with a finger so the
position of the shaft remains consistent.
(Tolerance: < 0.05mm)
Measure both ends of the shaft flange to ensure it is flat; the
difference between the two ends of the flange should be
0.01mm or less.
4. Next, use spool A as the reference and measure the height of
spools A to T. Note that the height of the spool should be
measured when it is at the upper limit (2). Measure at 200
degrees. Push down on the flange slightly with a finger so the
position of the shafts remains consistent.
(Tolerance: < 0.15mm)
5. Next, measure the stroke of the 12
th
station. Measure at 200
degrees. Put the dial gauge in the center of the clutch underside
(3). Find the lowest shaft (the shaft that pushes down the least)
and set the stroke for this shaft within the range of 0.3 to
0.35mm. Note that 0.31mm is the ideal value. Also be aware
that when rotating the shaft the stroke amount will change; set
the stroke where the clutch underside is lowest. When rotating
the shaft, the fluctuation in the stroke amount should be less
than 0.03mm.
6. As mentioned above, the stroke of the lowest shaft should be
within the range of 0.3 to 0.35mm. The stroke of all the other
shafts must be within the range 0.3 to 0.45mm.
7. For the adjustments that follow in Chapter 5, it is necessary to
establish the following three values:
1. Identifying the low shaft. (the clutch which pushes down the least)
2. Identifying the shaft with the average clutch stroke.
3. Identifying the shaft with the low spool valve.
