Function
Sets the bias voltage applied to the
development roller for the ID sensor pattern.
(0: –200 V= Normal
1: –160 V= Lighter
2: –220 V= Darker
3: –240 V= Darkest)
Selects the image density level in ADS mode.
(Data 1: Increases charge grid voltage [–50 V].
Development bias voltage has standard value.
Data 2: Increases development bias voltage
[–40 V]. Charge grid voltage has standard
value.)
Black ID sensor check is performed every 5
copies or 10 copies.
(If low image density occurs in the toner near
end condition, change the data to "1".)
Selects the margin on the right side of the
reverse page in duplex 1 mode.
(For type 2 copier only. When duplex 1
[1-sided original mode] is selected, this margin
is automatically added.)
Adjusts black bias voltage if the image density
at level 4 cannot be adjusted by (SP48
exposure lamp voltage).
This must be done only other replacing the
OPC drum.
(0: Vo = Normal
1: Vo +40 V = Darkest
2: Vo +20 V = Darker
3: Vo –20 V = Lighter
4: Vo –40 V = Lightest)
Selects the width of the edge erase margin.
(Only when the editor is installed.)
Selects the width of the center erase margin.
(Only when the editor is installed.)
Adjusts the stop position of the jogger fences.
(For type 2 copier only. 0.5 mm per step. [max,
–4.0 mm to +3.5 mm].)
Adjusts lead edge erase margin.
(0.5 mm per step [max –4.0 mm to +3.5 mm].)
Adjusts lead edge registration.
(0.5 mm per step [max –4.0 mm to +3.5 mm].)
Adjusts magnification in the paper travel
direction.
(0.2 % per step. [max. –1.6% to +1.4%].)
