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
801
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
802
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.
Developer Initialization Data
1
TD Sensor
Displays the TD sensor output after performing the
developer initialization. This value will be used in fixed
supply mode.
803*
2
ID Sensor PWM Value
Displays the PWM value of the ID sensor after
performing the developer initialization.
Separation Voltage Adjustment
1
Front – Leading 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.
[–1000 ~ 4000 /
–1800
/ 1 V/step]
2
Front – 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.
[–1000 ~ 4000 /
–1800
/ 1 V/step]
3
Rear –
Leading Edge
Adjusts the voltage applied to the separation plate,
during printing at the leading edge of the paper on the
rear side.
See SP2-901-1.
[–1000 ~ 4000 /
–2100
/ 1 V/step]

4
Rear – Image Area
Adjusts the voltage applied to the separation plate,
during printing at the image area of the paper on the
rear side.
See SP2-901-2.
[–1000 ~ 4000 /
–2100
/ 1 V/step]
