SERVICE PROGRAM MODE
B089/B093 4-20 SM
2301 7 Temp Inside the Machine
Displays the temperature measured inside the machine just after power-on (by the
thermistor on the SBCU board) the last time that the fusing unit was less than
40
°
C just after the machine was switched on.
The transfer current is corrected in accordance with this value.
Developer Initialization 2801
Initializes the developer and resets the TD and ID sensor outputs to their defaults.
Use this if the machine did not detect the new PCU when it was installed, and the
TD/ID sensors were not initialized.
Developer Mixing 2802
Mixes the developer and checks Vt. The machine mixes the developer for 2
minutes and while doing this, it reads the TD sensor output (Vt). It does not
initialize the TD sensor output.
If the machine has not been used for a long time, prints may have a dirty
background. In this case, use this SP mode to mix the developer.
2803* Developer Initialization Data
2803 1 Vts
When the machine detects a new PCU (photoconductor unit) in the machine, it
checks the heat seals at the creation of the first ID sensor pattern. After the
agitator is rotated for 30 sec., the machine creates the second ID sensor pattern
and corrects the reference value of the TD sensor. The corrected reference value
for the TD sensor is recorded here.
2803 2 ID Sensor PWM Value
Displays the PWM value of the ID sensor after performing the developer
initialization. This value is added to the value of SP2934 4 (PWM Start Value for
Vsg Auto Adjust).
2803 3 Flag DFU
