3001 ID Sensor Initial Setting
001 PWM Setting
002 Initialization
3103 ID Sensor Output Display (Vsp, Vsg)
Displays the values for Vsp/Vsg (0.0V~5.0V)
001 Vsg Measured reflection of bare drum surface.
002 Vsp Measured reflection from ID sensor pattern.

001 On Timing
002 Off Timing
3920 ID Sensor Timing
Determines the intervals between ID sensor checks. An ID sensor pattern is made after
printing a page, if the print length since the last ID sensor check has reached the
specified value. The numbers below are centimeters.
[20~1000/1 cm]
Adjusts PWM. DFU
[0~1000/1]
Automatically adjusts the output to 4.0 ±0.2V. During
auto adjustment, the voltage applied to the ID Sensor
LED depends on the PWM value.
Press the Start button to initialize the ID sensor LED
with the value entered for the PWM. Initialization
requires about 4 seconds.
Note: Do this SP cleaning the ID sensor and after
replacement of the drum, ID sensor, NVRAM and
BCU.
Adjusts the development bias on timing.
[-222~+222/1 ms ]
Adjusts the development bias off timing.
[-222~+222/1 ms ]
