SP3 Mode Number Function and [Setting]
ID Sensor Initial Setting
01 ID Sensor PWM Setting Allows you to reset the PWM (Pulse Width
Modulation) of the ID sensor LED to avoid a
service call error after clearing NVRAM or
replacing the NVRAM.
[0 ~ 255 / 100 / 1 step]
The PWM data is stored by executing SP3001-
02.
3001*
02 ID Sensor Initialization Executes the ID sensor initial setting. ID sensor
output for the bare drum (V
SG
) is adjusted
automatically to 4.0 ±0.2 V.
Press # to start. Perform this setting after
replacing or cleaning the ID sensor, replacing
the drum, or clearing NVRAM.
ID Sensor Output Display Displays the current V
sg
, V
sp
, V
sdp
, and
grayscale control in the range 0 V ~ 5.00 V.
Press #(Enter), press

to select the item to
display, then press #(Enter).
This SPs are for display only; you cannot adjust
the settings.
01 Vsg Vsg is the ID sensor output after reading the
bare drum surface.
Normal display: 4±0.5 V
SC350 (ID Sensor Pattern Test Error) is issued if
this reading is abnormal.
02 Vsp Vsp is the ID sensor output after reading the ID
sensor pattern:
Normal display: 0.1 ~ 0.3
SC351 (ID Sensor Vsg Test Error) is issued if
this reading is abnormal.
03 Vsdp Vsdp is the ID sensor output immediately after
Vsp output when the charge potential drops.
This reading is used for design purposes to
determine the development characteristics. DFU
Normal display: 3.4 ~ 4.0
SC352 (ID Sensor Edge Detect Pattern Error) is
issued if this reading is abnormal.
3103*
04 Vsm/Vsg
Vsm is the ID sensor output after reading the
intermediate halftone pattern (grayscale) portion
of the ID sensor pattern.
Normal display: 65% ~ 85% (SP2972)
The addition of the intermediate halftone pattern
to the ID sensor pattern is a new feature. Vsm is
used (Vsm/Vsg) to determine the power level
adjustment of the LD. The LD power level is
adjusted automatically to ensure the quality of
images, slow deterioration of the OPC over time,
and reduce scatter.
