2606 OHP FC Bias Set Bias for Transparency: K
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.

2611 Size Coeff:OHP Size Correction Coefficient for Transparency
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.

2613 Size Coeff:OHP Size Correction Coefficient for Transparency
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.

2621 LEdge Cor:OHP K Leading Edge Correction for Transparency: K
These SPs do the following settings when printing on OHP in the black-and-white
mode at half-speed (128~256 g/m
2
):
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 Leading Edge Switch Timing for Transparency: 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
2
).
