2101 10 Printer - Rear Trailing Edge
In printer mode, adjusts the trailing edge erase margin on the reverse side of
duplex copies.
The actual trailing edge erase margin on the reverse side is this value plus the
value of SP21017.
The specification is 3
±
2 mm. See “Replacement and Adjustment - Copy
Adjustment” for details
[0.0 ~ 9.0 / 0.0 / 0.1 mm/step]
LD Power Adjustment [50 ~ 170 / 129 / 1/step] 2103*
Adjusts the LD power. DFU
Do not change the value.
Test Mode dpi 2110*
Sets the scanning resolution (dpi). DFU
[See below / 8 / 0~18]
0: 400x400 dpi 1: 391x406 dpi
2: 406x391 dpi 4: 300x300 dpi
8: 600x600 dpi 15: 439x430 dpi
16: 476x476 dpi 17: 483x465 dpi
18: 465x483 dpi
2201* Development Bias Adjustment
2201 1 Printing
Adjusts the development bias during printing.
This can be adjusted as a temporary measure if faint copies appear due to an
aging drum.
[–1500 ~ 2000 / –650 / 1 V/step]
2201 2 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 SP22011.
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
2210 1 Charge Bias
Adjusts the charge voltage (-1200V) application time.
DFU
When the charge voltage and development bias are turned off at the same time,
toner 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.
[0 ~ 150 / 80 / 1 ms /step]
2210 2 Development Bias
Adjusts the development bias off time.
DFU
[-120 ~ 120 / 0 / 1ms/step]
