Toner Supply
2207: Forced toner supply.
2208: Toner supply mode.
Keep at sensor control mode . The machine automatically changes to pixel control
mode if the TD sensor is broken. Make sure that it changes back to sensor control
mode after replacing the sensor.
2209: Toner supply rate.
A higher value gives a higher toner supply rate, requiring less time for toner supply.
This setting is important if the user commonly copies documents with a high
proportion of black.
2210 etc: ID sensor pattern intervals were discussed on an earlier slide in this section.
2223: Displays the average of the latest 16 TD sensor output voltages measured.
2801: TD sensor initial setting
2967: As mentioned in the Process Control section, the ID sensor is unreliable in some
environments
2972: In very hot environments, this SP setting must be changed, so the fan will stay on all
the time (unless the main switch is turned off). This will prevent toner particles from sticking
together.
Normally, the fan turns off in night mode and when the operation switch is switched
off.
3001 002: ID sensor initial setting
Use 3-001-1 if you forgot to do an ID sensor initial setting after resetting or replacing
the NVRAM on the BICU.
PWM (Pulse Width Modulation) for the ID sensor refers to the input voltage
required to get the standard output of 4
3103: Latest ID sensor output – this displays VSG (from the bare drum) and VSP (from the
black ID sensor pattern)
SP Modes

0.2 V.
