Polyg MO Off T. Polygon Motor Off Timer
[0 ~ 60 s / 10 s / 5 s step]
Input the time that the polygon motor is to switch off after the printer has remained idle for the
specified time and entered the standby mode.
If set to zero, the polygon motor never switches off in standby mode. However, if the machine
enters the energy saver mode, the polygon motor will ignore the zero setting and switch itself
off.
2201 Developer Bias Development Bias Adjustment
001
Image Dev Bias [-200 ~ -700 / -540 V / 10V step]
Adjusts the development bias for copying.
Use as a temporary measure to correct faint copies from an aging drum.

Force Toner Supp Forced Toner Supply
Forces the toner bottle to supply toner at 1-second intervals for up to 30 seconds. To start, press
[#Enter].
2208
Toner Supp Mode Toner Supply Mode
[0: Sensor control, 1: Image pixel count
Selects the toner mode.
If you select 1, SP2-209-002 should be set to its default value. Use image pixel count modes
only as a temporary measure if the ID or TD sensor is defective.
2209 Toner Supp Rate Toner Supply Rate
[0 ~ 800 / 60 mg/s / 5 mg/s step]
Sets the amount of toner supplied every second by the toner supply motor. The length of time
the motor remains on is determined by the data from the TD sensor and ID sensor.
Increasing this value reduces the toner supply clutch on time. Use a lower value if the user tends
to make lots of copies that have a high proportion of black.
