Displays the fusing temperature detected by the
fusing thermistor.
Press the key to monitor the temperature
during the normal copy cycle.
If the setting of SP30 (Toner Supply Mode
Selection) is 1 or 3, this value is used for the TD
sensor target voltage.
Normally, this value should not be changed.
When the TD Sensor initial setting is performed, this
mode is adjusted automatically.
Normally, this value should not be changed.
!
Displays the TD sensor output voltage.
Press the key to monitor the output voltage
during the normal copy cycle.
The output voltage will display "0" when this mode is
accessed after turning on the main switch without
making any copies.
Adjusts the ADS reference voltage.
After adjusting the light intensity (SP48), place 5
sheets of A4(LT) white paper on the exposure glass
and select this mode. Adjust the ADS voltage to 2.5
V ± 0.1 V using VR101 on the main control board.
!
Displays the ADS output voltage.
Press the key to monitor the output voltage
during the normal copy cycle.
For only this SP mode, the copies are made with the
ADS mode (other SP modes use manual ID level 4).
Adjusts the image density at ID level 1 by changing
the development bias voltage.
