PRINTER ENGINE SERVICE MODE
Function and [Setting]
Printing the second side of the paper (image
area) during duplex printing.
[20 ~ 100 µA / 45 / 1 µA step]
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]
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]
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]
Adjusts the lower paper width threshold for the
transfer current, charge voltage, and
development 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]
Adjusts the upper paper width threshold for the
transfer current, charge voltage, and
development 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]
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2309-01. DFU
[1.0 ~ 3 / 1.2 / 0.1 mm step]
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2309-02. DFU
[1.0 ~ 3 / 1.2 / 0.1 mm step]
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2309-01. DFU
[1.0 ~ 3 / 1.5 / 0.1 mm step]
Adjusts the transfer current correction coefficient
used if the paper width is less than the setting of
SP2309-02. DFU
[1.0 ~ 3 / 1.5 / 0.1 mm step]
