Mode Number/Name
Function/[Setting]
Toner Density Control Level Adjustment
932*
Adjusts the toner density control threshold level.
[
0 = Normal
/ 1 = Dark / 2 = Light / 3 = Darker / 4 =
Lighter]
Use this SP when you want to adjust the image
density.
ID Sensor Control Coefficient
933*
Adjusts the ID sensor control coefficient.
DFU
[5 ~ 30 /
10
/ 1/step]
ID Sensor PWM Setting
1
Display
Displays the PWM of the ID Sensor LED.
2
PWM Upper Limit
Adjusts the upper limit of the PWM for the ID sensor
LED.
DFU
[0 ~ 999 /
0
/ 1/step]
934*
3
PWM Upper Limit
Correction
Corrects the upper limit of the PWM for the ID sensor
LED.
DFU
[0 ~ 999 /
0
/ 1/step]
ID Sensor Initialization
935
Performs the ID sensor initial setting.
Press
Execute on the touch panel
to start. Perform this
setting after replacing or cleaning the ID sensor.
ID Sensor Pattern Size
936*
Selects the ID sensor pattern size in the main scan
direction.
Set to 1 if white spots or black spots appear on prints.
The ID sensor pattern is 290 mm wide, and when this
is cleaned off, dirt is removed also.
[
0 = 20 mm
/ 1 = 290 mm]
Copies After TD Sensor Error
992*
Selects the number of copies that can be made after a
TD sensor error has been detected. When the machine
copies this amount, an SC condition will occur.
If the optional fax unit is installed, the SC condition
occurs immediately regardless of the number of prints
(this is because the sender of the fax cannot check the
image quality of the printout).
[
0 = 100 copies
/ 1 = 200 copies]
Vts Limitation
1
Upper Limit (Factory)
DFU
994*

Lower Limit (Factory)
DFU
ID Sensor Detection Interval
995*
1
Warming-up
If the machine starts warming-up after this time has
passed since entering
energy saver mode or auto off
mode,
the machine makes an ID sensor pattern.
If this value is greater, there is a greater chance that
background will become dirty.
[0 ~ 999 /
30
/ 1 minute/step]
955*

Number of Page
The machine makes an ID sensor pattern after the
specified number of prints has been made. 0 = this
feature is disabled.
