Chapter 3 – Static Accuracy Measurement
3.1 Straightness of the X/Y Axes
1. Equipment: perpendicular measurement jig (Z9531DEPJ0050). Dial gage (0.01mm).
2. Attach the dial gage to the placement head (an extension bar is necessary).
3. Place the perpendicular measurement jig (Z9531DEPJ0050) on the conveyor. Adjust the
jig position so that when running the dial gage along the jig in the X direction, the 0mm
and 300mm point values are both “0” (i.e. the jig is parallel to the X axis).

4. Measure the Y axis straightness in the same way as the X-axis. Measure in the part
placement area of the main conveyor.

3.2 Perpendicularity of the X/Y Axes
1. Equipment: perpendicular measurement jig (Z9531DEPJ0050). Lever type dial gage
(0.01mm).
2. Load the perpendicular measurement jig on the conveyor. Adjust the jig position so that
when running the dial gage along the jig in the X direction, the 0mm and 300mm point
values are both “0” (i.e. the jig is parallel to the X axis).
3. With the jig in this position, measure the Y-direction side. This indicates the
perpendicularity of the X and Y axes.
4. Measure in the part placement area of the main conveyor.

3.3 Piston Deviation
1. Equipment: lever type dial gage (0.01mm).
2. Bring the number 1 nozzle to the front of the machine and set the dial gage on the top of
the nozzle piston as illustrated in the following photo:
3. Using the number 1 nozzle piston height as a reference, move the R axis through one
rotation and measure all the remaining pistons.
4. The height difference between the highest and lowest piston should be within 0.10mm.
If out of tolerance please contact FUJI. Also record which of the 12 pistons is the highest
(this information is necessary for later adjustments).
3.4 Backlash
1. Equipment: lever type dial gage (0.002mm).
2. With the servo ON set the dial gage against the X and Y axes in turn and measure the
backlash.
3. Any backlash should be within 0.01mm.
4. In the case of the Q and R axis gears there should be no backlash.
