2802
Developer Mixing
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
1
Vtref
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.
2
ID Sensor PWM Value
Displays the PWM value of the ID sensor after performing the developer initialization.
2901* Separation Voltage Adjust
1
1side:Lead Edge
Adjusts the voltage that is applied to the separation plate during printing at the leading
edge of the paper on the front side.
If the copies have pawl marks at the leading edge, increase this voltage.
[–4000 to 0 / –1800 / 100 V/step]
2
1side:Image Area
Adjusts the voltage that is applied to the separation plate during printing on the image
area of the paper on the front side.
If the copies have pawl marks in the image area, increase this voltage.
[–4000 to 0 / –1800 / 100 V/step]
