Printing 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 ~ 100 μA / 45 / 1 μA step]
004
Img Face Bypass Image Face By-pass (By-pass Feed)
Printing from the by-pass tray (image area).
If the user normally feeds thicker paper from the bypass tray, use a higher setting.
[20 ~ 100 μA / 45 / 1 μA step]
005
Lead Face Bypass Leading Edge By-pass Feed
Printing 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 ~ 100 μA / 60 / 1 μA step]

Trans Curr Corr Transfer Current Correction
01 a (Paper Lower Width)
Adjusts the lower paper width threshold for the transfer current, charge voltage, and develop-
ment bias corrections. DFU
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 SP2309-03 (paper tray) or SP2309-05 (by-pass).
[0 ~ 297 / 150 / 1 mm step]
02 b (Paper Upper Width)
Adjusts the upper paper width threshold for the transfer current, charge voltage, and devel-
opment bias corrections. DFU
As for SP2309-01, but the factors are in SP2309-04 (paper tray) and SP2309-06 (by-pass).
[0 ~ 297 / 216 / 1 mm step]
03 Alpha (Tray)
Adjusts the transfer current correction coefficient used if the paper width is less than the setting
of SP2309-01. DFU
[1.0 ~ 3.0 / 1.2 / 0.1 mm step]
