11.4 ATDC Sensor Automatic Adjustment

• The reference value for the ATDC Sensor is automatically adjusted as detailed below
using the ATDC Sensor Automatic Adjustment mode.
With the copier set in the ATDC Sensor Automatic Adjustment mode, press the Start key.
The developer is mixed.
The ATDC Sensor converts the reference T/C (14 %) to a corresponding voltage
value and outputs it.
Does the output voltage fall within the range from 2.28 to 2.36 V?
YES
The voltage input to the ATDC Sensor
from the Master Board at this time is fixed
as the reference voltage.

NO
The voltage input to the ATDC Sensor from
the Master Board is varied.
2.37 V or more: Decrease the voltage.
2.29 V or less: Increase the voltage.
