Polygon Motor Off Timer
[0 ~ 60 s /
10 s
/ 5 s step]
2112
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.

Development Bias Adjustment
Development Bias
[-200 ~ -700 /
-560V
/ 10V step]
2201 1*
Adjusts the development bias for copying.
Use as a temporary measure to correct faint copies from an aging drum.
ID Sensor Pattern
[- 200 ~ -700 / -
480V
/ 10V step]
2201 2*
Adjusts the development bias for the ID sensor pattern for V
SP
Forced Toner Supply
2207
Forces the toner bottle to supply toner at 1-second intervals for up to 30 seconds.
To start, press
.
Toner Supply Mode
[
0
: Sensor control, 1: Image pixel count]
2208
*
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 Supply Rate
Toner Rate
[10 ~ 800 /
60 mg/s
/ 5 mg/s step]
2209 1
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 read by 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.
Toner Supply Correction Data
[25 ~ 300 /
300
/ 25 step]
2209 2*
Displays the toner supply correction coefficient (K). It can also be used to adjust K,
but the value is changed again when V
T
is measured for the next copy.
The toner supply rate depends on the amount of toner in the toner bottle. This
change is corrected using this coefficient. This SP can be used to check the toner
supply condition. The lower the value of K, the lower the toner density
ID Sensor Pattern Interval
2210
*
Sets the interval between ID sensor pattern prints.
Job Page Count
[0 ~ 200 /
10
/ 1]
2210 1*
Sets the interval between ID sensor pattern printing. For users that do not make
many copies daily, set a smaller interval to compensate for the effects of seasonal
and weather changes.
Forced Page Count
[2 ~ 999 /
200
/ 1]
2210 2*
Forces creation of the ID sensor pattern to prevent low density copies for
customers who use the copier for long copy jobs.
