2606 OHP FC Bias
This SP sets the following standard bias voltages applied for the image area on OHP
in the full-color mode at 1) image transfer from drum to ITB for each color, 2) image
transfer from ITB to paper, and 3) at paper separation from the ITB.
001 ITB: K
002 ITB: M
003 ITB: C
004 ITB: Y
005 PTR
006 SepDC
007 SepAC
2611 Size Coeff:OHP
This SP setting applies to 1) OHP widths above Threshold 1 (SP2308 001), 2) the
image area only, 3) OHP only, 4) either black-and-white or full-color mode.
002 Size :PTR
2613 Size Coeff:OHP
This SP setting applies to 1) OHP widths larger Threshold 3 (SP2308 002) and
smaller than Threshold , 2) the image area only, 3) OHP only, 4) either black-and-
white or full-color mode.
[100~600/1%]
2621 LEdge Cor:OHP K
These SPs do the following settings when printing on OHP in the black-and-white
mode at half-speed (128~256 g/m
1) ITB: Sets strength/timing of the correction coefficient for the application of bias
when the image is transferred from the drum to the ITB.
2) PTR: Sets the strength/timing correction coefficient for the application of bias
when the image is transferred from ITB.
3) SepDC, SepAC: Set the strength/timing of the dc and ac charges applied to
neutralize the charges on the belt and paper so they will separate more easily.
Note: SP2621 selects the strength of the bias coefficient, and SP2622 sets the start
timing of the bias application.
2622 LEdge SWT:OHP K
Sets the switch OFF timing of SP2626. The selected value is the number of mm from
the leading edge. Applies only to printing in black-and-white mode on OHP in half-
speed mode (128~256 g/m
