4.2 Troubleshooting problems in initializing disks positions
4.2.1 PI sensors information on the main board
4.2.1 Any of the disks is slightly off-position and comes in the same position
every time after its initialization
It’s attributed to a physical change in sensing position or condition. It may be fixed
by motor calibration. Refer to the appendix for the how-to.
4.2.2 A disk stops at a random position after the initialization
It’s attributed to a defective PI sensor for the disk. Follow the check procedure
below to fix this problem.
① Find the position of related PI sensor for the disk.
② Try cleaning the soldered side of the PI sensor PCB with alcohol swab.
③ If not fixed, replace the PI sensor.
Æ After replacing the sensor PCB, it is required to check the disk position of the
disk after its re-initialization. It’s not possible to re-align the disk position 100%
precisely in the outside of the factory but possible within the tolerance manually.
