SP3 Mode Number Function and [Setting]
3001* ID Sensor Initial Setting
* 1* ID Sensor PWM Setting Allows you to reset the PWM 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 SP-3001-2.
2* ID Sensor Initialization Performs 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.
3103* ID Sensor Output Display
Displays the current V
SG
, V
SP
, V
SDP
, and
grayscale control.
1* Vsg (Drum Surface Output)
2* Vsp (Pattern Output)
3* Vpdp (Immediate Post-
Pattern Output).
4* Vsm/Vsg (Immediate
Grayscale Post-Pattern
Output)
[0V ~ 5.00V]
If the ID sensor does not detect the ID pattern,
V
SP
= 5.0 V/V
SG
= 5.0 V
is displayed and an SC code is generated.
If the ID sensor does not detect the bare area of
the drum,
V
SP
= 0.0 V/V
SG
=0.0 V
is displayed and an SC code is generated.
