2nd Toner Conveying Roller
ATDC Sensor UN1
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 2.36 to 2.44 V?
YES NO
The voltage input to the ATDC Sensor from the
Master Board at this time is fixed as the reference
voltage.
The voltage input to the ATDC Sensor from
the Master Board is varied.
2.45 V or more: Decrease the voltage.
2.35 V or less: Increase the voltage.
