3001* ID Sensor Initial Setting
ID Sensor PWM Setting [0 ~ 255 / 100 / 1 step] 3001 1
Allows you to reset the PWM of the ID sensor LED to avoid a service call error
after clearing NVRAM or replacing the NVRAM.
The PWM data is stored by executing SP-3001-2.
ID Sensor Initialization — 3001 2
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 “Execute” to start. Perform this setting after replacing or cleaning the ID
sensor, replacing the drum, or clearing NVRAM.
ID Sensor Output Display 3103*
Displays the current V
SG, VSP, VSDP, and grayscale control
If the ID sensor does not detect the ID pattern, “V
SP = 5.0 V/VSG = 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/VSG =0.0
V” is displayed and an SC code is generated.
3103 1* Vsg (Drum Surface Output) [0V ~ 5.00V]
3103 2* Vsp (Pattern Output) [0V ~ 5.00V]
3103 3* Vsdp (Immediate Post-
Pattern Output).
[0V ~ 5.00V]

Pattern Output)
[0V ~ 5.00V]
Hot Roller Stripper Cleaning After Job 3905*
Toner and carbon clinging to the hot roller strippers can cause poor print quality.
To prevent this, toner and carbon are dislodged from the hot roller strippers in two
ways: 1) jogging the fusing/feed-out motor 3 times after every print job. 2) freely
rotating the hot roller for 12 s. For details, see Section “6.6.2 Hot Roller Stripper
Cleaning”. Also see SP 5959.
Number of Rotations [0 ~ 60 / 1 / 1 ] 3905 1*
Sets the number of times the fusing/exit motor is switched off/on in order to
dislodge toner clinging to the hot roller strippers.
Raising this setting can increase wear on the hot roller and cleaning roller and
shorten the service life of the hot roller.
Number of Pages [0 ~ 1000 / 15 / 1] 3905 2*
Sets the number of pages to print before the fusing/feed-out motor is jogged
(switched off and on rapidly) to dislodge toner and carbon from the hot roller
strippers.
Normally the motor is jogged once (switched off and on rapidly) after every print
job that exceeds 15 pages.
