Performs the ID sensor initial setting. The ID sensor output for the bare drum
(VSG) is adjusted to 4.0 ± 0.2V.
Press "Execute".
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 Display
001 Vsg
Displays the current value of the ID sensor output after checking the bare drum
surface.
[0 to 5/0/0.01 V]
002 Vsp
Displays the current value of the ID sensor output after checking the ID sensor
pattern image.
[0 to 5/0/0.01 V]
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.
[0 to 5/0/0.01 V]
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 Control On/Off Setting
