NOTE
Basically, the lubricating the spline shaft (Z-axis) is not required. However, the grease on the spline shaft surface is
removed by touching with hand or by sprinkling solvent. As a result, the spline shaft gets easily rusted. Apply the
specified grease (NSL) slightly for anti-rusting as needed.

4.6 Checking the SC-axis flex cable
The SC-axis flex cable is a flat multi-cable designed for rigidity to prevent the harness from drooping as it
moves along with the scan camera. However, the cable may eventually droop due to warping or weakening
from long-term use. If cable drooping occurs, then the cable may come in contact with moving parts and cause
trouble. We recommend making periodic checks and replacing the cable if drooping becomes obvious.
