ID Sensor Pattern
Adjusts the development bias for making the ID sensor pattern.
The actual development voltage for the ID sensor pattern is this value plus the value of
2
SP2201-1.
This should not be used in the field, because it affects ID sensor pattern density, which
affects toner supply.
[0 = N (200V) / 1 = H (240V) / 2 = L (160V) / 3 = HH (280V) / 4 = LL (120V)]
2210* Bias Off Time
Charge Bias
Adjusts the charge voltage (-1200V) application time.
When the charge voltage and development bias are turned off at the same time, toner
1
or carrier will be attracted to the drum. To reduce the toner or carrier attraction, the
machine applies –1200V to the charge roller before the development bias is turned
off. This SP adjusts the time for applying the charge.
[10 to 150 / 100 / 10 ms /step]
Development Bias
2
Adjusts the development bias off time.
[10 to 200 / 80 / 10 ms/step]
PCU Reverse Interval
Adjusts the PCU reverse interval for cleaning during a job.
When the machine has made this number of copies in the middle of a job, the machine
2211*
reverses to clean the edge of the cleaning blade. After cleaning, the machine resumes
the job. Set to a shorter interval if thin white lines appear on printouts.
[0 to 999 / 100 / 1 sheet/step]
0: Never cleans during job
Copies After Toner Near End
Selects the number of copies that can be made after toner near-end has been detected.
2213*
[0 = 50 pages / 1 = 20 pages]
If the user normally makes copies with a high proportion of black, reduce the interval.
