If not adjusted, perform the steps below.
1)
Remove the MR sensor holding plate, correct the position of MR sensor holding plate block as shown in Fig. 5-9-21.
2)
Install the MR sensor holding plate, perform the MR waveform inspection again.
3)
Repeat steps 1) and 2) until the inspection OK.
4)
After completing the adjustment, apply the adhesive bond (B-10) to the tip of two screws.

3. Motor Assembly Inspection
The following pop-up window is one example.
Fig.5-9-22
If the NG judgment continues three times in the motor assembly inspection, perform the MR waveform inspection.
When the MR waveform inspection is OK, perform the adjustment of MR sensor.
When the MR waveform inspection is NG, replace the ultrasonic motor unit.
4. DMF Ring Rotation Detector SW Inspection
The following pop-up window is one example.
