changed from "every 100 prints" to
"every (100 X (SP2-974 value + 1))

This SP mode is added to recover the
machine when an SC condition occurs
because ID Sensor Initial Setting is 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.
