2927* ID Sensor Control
Selects whether the ID sensor is used or not for toner density control.
[0 = No / 1 = Yes]
If this value is "0", dirty background may occur after the machine has not been
used for a long time.
2928* Toner End Clear
Clears the toner end condition. Press Execute on the touch panel to clear the
toner end condition without adding new toner.
When you press Execute, the following are cleared:
• Toner end indicator (goes out)
• Toner near-end counter
• Toner near-end level
When making a lot of copies after changing this setting to "1", the carrier may be
attracted to the drum when the toner runs out, which may damage the drum.
2929* Vref Adjustment
2929 1 Upper Limit
Adjusts the upper limit for Vref. [0.5 ~ 3.5 / 3.10 / 0.05 V/step]
2921 2 Lower Limit
Adjusts the lower limit for Vref. [0.5 ~ 3.5 / 1.40 / 0.05 V/step]
2930* TD Sensor Manual Setting
Adjusts the TD sensor output. DFU
[0 ~ 5 / 0.0V / 0.05V/step]
2931* TD (V/wt%) Setting
Adjusts the TD sensor sensitivity (coefficient: S) for toner density control. DFU
[0.01 ~ 1.50 / 0.4 / 0.01/step]
2932* Toner Density Control Level
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.
2933* ID Sensor Control Correction
Adjusts the ID sensor control coefficient. DFU
[0.5 ~ 3 / 1 / 0.1/step]
2934* ID Sensor PWM Setting
2934 1 Display
2934 2 Upper Limit
Adjusts the upper limit of the PWM for the ID sensor LED. DFU
[0 ~ 1279 / 0 / 1/step]
2934 3 Upper Limit Correction
Corrects the upper limit of the PWM for the ID sensor LED. DFU
[0 ~ 255 / 50 / 1/step]
SM
SERVICE PROGRAM MODE
Displays the PWM of the ID Sensor LED.
