Factory use only
Use this SP mode when an SC condition

occurs because ID Sensor Initial Setting
was not done after doing an NVRAM Clear
or replacing the NVRAM. Reset this SP to
the factory setting in this case.
The PWM data is stored when ID Sensor
Initial Setting is done.

Performs the ID sensor initial setting. The
ID sensor output for the bare drum (V
adjusted to 4.0 ± 0.2V.
This SP mode should be performed after:
1. Replacing or cleaning the ID sensor
2. Replacing the NVRAM or doing an
NVRAM clear
3. Replacing the SBICU board
