3001 ID Sensor Initial Setting
001 ID Sensor PWM Setting
This SP mode recovers the machine when an SC condition occurs because ID Sensor
Initial Setting is not done after doing an NVRAM Clear or replacing the NVRAM. Reset
this SP to the factory setting in this case.
[0~255 / 62 / 1]
The PWM data is stored when ID Sensor Initial Setting is done.
002 ID Sensor Initialization
Performs the ID sensor initial setting. The ID sensor output for the bare drum (VSG) is
adjusted to 4.0 ± 0.2 V.
This SP mode should be performed: 1) After replacing or cleaning the ID sensor, 2)
After replacing the NVRAM or doing an NVRAM clear.
3103 ID Sensor Output Display
001 Vsg
Displays the current value of the ID sensor output after checking the bare drum surface.
002 Vsg Initial
Displays Vsg when the Vsp adjustment is done.
003 Vsp
Displays the current value of the ID sensor output after checking the ID sensor pattern
image.
004 Vsdp
Displays the value of the ID sensor output immediately after Vsp is output when the
charge potential drops. This reading is used to test and determine characteristics for
design. DFU
3901 Auto Process Control Setting
001 Auto Process Control Setting
Determines whether machine checks and corrects drum potential (Vd) and LD power
when the fusing temperature is lower than 100°C at power-on.
[0~1 / 1/ 1]
0: OFF
1: ON
This setting attempts to change the Vd setting consistent with the OPC, the charge
corona unit, and environment to improve the reliability of the system.
002 VL Correction Control Setting
Determines whether VL detection and correction are performed during process control
every 1K copies.
[0~1 / 0/ 1] DFU
0: OFF
1: ON
Even with this SP switched ON, VL detection and correction will not be performed if
SP3901 001 is OFF.
