Ricoh G148, Service Manual

Page: 341 / 537

This SP mode should be performed after:
(1) Replacing or cleaning the ID sensor, (2) Replacing the NVRAM, (3) Clearing NVRAM,
(4) Replacing the BICU board.
3103 [ID Sensor Output] ID Sensor Output Display
001 Vsg
Displays the current value of the ID sensor output after checking the bare drum surface.
002 Vsp
Displays the current value of the ID sensor output after checking the ID sensor pattern image
003 Vpdp
Displays the current 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.
Note: If the ID sensor output is abnormal, an SC is logged and the displays change:
• SC350-01 logged: Vsp/Vsg/Vsdp = 0.00/0.00/0.00
• SC350-02 logged: Vsp/Vsg/Vsdp = 5.00/5.00/5.00
• SC350-03 logged: Vsp/Vsg/Vsdp = 0.01/0.01/0.01
3901 [Auto Process Con Set] Auto Process Control On/Off Setting
Determines whether the machine checks and corrects the drum potential (Vd) and LD power
when the fusing temperature is lower than 100
°
C at power-on.
[0~1/1]
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.
3902 [Drum Condition D] Drum Condition Display
001 Auto Process Control On/Off
Displays whether auto process control is switched on or off (0:Off, 1:On)
When auto processing control is set on, displays only when the potential sensor is calibrated
correctly. Auto process control is not executed when this SP is switched off.
