1
Mode Number/Name Function/[Setting]
Punch Hole Detection994
When using paper that has punch holes, the
registration sensor may detect the hole and a paper
jam will be detected. If you select “1”, the machine
ignores the registration sensor off signal within 50 mm
from the trailing edge of the paper.

Mode Number/Name Function/[Setting]
Charge Roller Bias Adjustment
1* Printing Adjusts the voltage applied to the charge roller during
printing.
This value will be changed automatically when the
charge roller bias correction is performed.
Note that if this value is changed, the charge roller
voltage will be corrected based on the new voltage.
[2100 ~ 1500 / –1700 / 1 V/step]
2* Charge Roller Bias
Adjustment
(ID sensor pattern)
Adjusts the voltage applied to the charge roller when
making the Vsdp ID sensor pattern (for charge roller
bias correction).
The actual charge roller voltage is this value plus the
value of SP2-001-1.
[0 ~ 400 / 200 / 1 V/step]

Charge Roller Bias
Adjustment
(Temporally input)
Inputs the charge roller voltage temporarily for test
purposes.
Do not change the value.
[0 ~ –2500 / 0 / 1 V/step]
Charge Roller Bias Correction
1 Vsdp Minimum
Adjusts the lower threshold value for the charge roller
correction.
When the value of Vsdp/Vsg is less than this value, the
charge roller voltage increases by 50V (e.g. from –500
to –550). The size of the increase depends on SP2-
005-3.
[0 ~ 100 / 90 / 1%/step]
2 Vsdp Maximum
Adjusts the upper threshold value for the charge roller
correction.
When the value of Vsdp/Vsg is greater than this value,
the charge roller voltage decreases by 50V (e.g. from –
550 to –500). The size of the decrease depends on
SP2-005-3.
[0 ~ 100 / 95 / 1 %/step]
005*
3 Step Adjusts the size of the charge roller voltage correction.
[0 ~ 200 / 50 / 1 V/step]
