SP2 Mode Number Function and [Setting]
2301* 3* Leading Edge Copying at leading edge of the paper.
Increase the current to separate the paper from the
drum properly in high humidity and high
temperature conditions.
[20~100µA / 35 (B004/B007: 45) / 1µA step]
4* By-pass Feed Copying from the by-pass tray (image area).
If the user normally feeds thicker paper from the
bypass tray, use a higher setting.
[20~100µA / 35 (B004/B007: 45) / 1µA step]
5* Leading Edge By-pass
Feed
Copying at the leading edge of paper fed from the
by-pass tray.
Increase the current to separate the paper from the
drum properly in high humidity and high
temperature conditions.
[20~100µA / 45 (B004/B007: 60) / 1µA step]
2309* Transfer Current Correction Corrects the transfer current for the items below.
1* Paper Lower Width (a) Adjusts the lower paper width threshold for the
transfer current, charge voltage, and development
bias corrections.
Use this SP when an image problem (e.g.,
insufficient toner transfer) occurs with a small width
paper. If the paper width is smaller than this value,
the transfer current will be multiplied by the factor in
SP2-309-3 (paper tray) or SP2-309-5 (by-pass).
[0~297 / 150 / 1 mm step]
2* Paper Upper Width (b) Adjusts the upper paper width threshold for the
transfer current, charge voltage, and development
bias corrections.
As for SP2-309-1, but the factors are in SP2-309-4
(paper tray) and SP2-309-6 (by-pass).
[0~297 / 216 / 1 mm step]
3*
Paper Tray (α)
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2-309-1.
[1.0~3 / 1.2 / 0.1 mm step]
4*
Paper Tray (β)
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2-309-2.
[1.0~3 / 1.2 / 0.1 mm step]
5*
By-Pass Feed (γ)
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2-309-1.
[1.0~3 / 1.5 / 0.1 mm step]
6*
By-Pass Feed (δ)
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2-309-2.
[1.0~3 / 1.5 / 0.1 mm step]
2801* TD Sensor Initial Setting Performs the TD sensor initial setting. This SP
mode controls the voltage applied to the TD sensor
to make the TD sensor output about 4.0 V. Press 1
to start. After finishing this, the TD sensor output
voltage is displayed.
Use this mode only after installing the machine,
changing the TD sensor, or adding new developer.
