Sp3Xxx Processing - Ricoh B064 Service Manual

SP3xxx Processing

3001* ID Sensor Initial Setting
001 ID Sensor PWM Setting
Recovers the machine when an SC is logged because the 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.
[0~255/1]
002 ID Sensor Initialization
Performs the ID sensor initial setting. The ID sensor output for the bare drum
(VSG) is adjusted to 4.0 ± 0.2V.
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.
002 Vsp
Displays the current value of the ID sensor output after checking the ID sensor
pattern image
003 Vsdp
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:
1) SC350-01 logged: Vsp/Vsg/Vsdp = 0.00/0.00/0.00
2) SC350-02 logged: Vsp/Vsg/Vsdp = 5.00/5.00/5.00
3) SC350-03 logged: Vsp/Vsg/Vsdp = 0.01/0.01/0.01
3901* 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.
