Adjusting the Secondary Transfer Voltage

You can adjust the Secondary Transfer Voltage (the voltage that transfers toner to the paper) when image blurring occurs.
When <2nd Side of 2-Sided Page> is set to <On> for custom paper or paper is loaded in the multi-purpose tray and <Paper Type> is set to <2nd Side of 2-Sided Page>, adjust the value in <Back Side>.
Adjustment in <-> Direction is Recommended for Following Cases
Adjustment in <+> Direction is Recommended for Following Cases
Paper Weight
Light (thin paper)
Heavy (thick paper)
Poor Images
Although the density in the high density areas is normal, tiny white spots may appear in the low density areas.
White spots appear in high density areas.
Enough toner is not applied in high density areas, and tiny dense spots appear.
Dense spots may appear in low-density areas.
In high-density images, streaks of uneven density may appear along the feeding direction.
High-density parts may not be sufficiently dense.
High-density images may be uneven in density.
Outlines in high density images may blur.
Corrupt images on uneven paper (C7700 Series only)
In concave portions of paper with uneven surfaces (such as textured paper), the density of low-density images may be too light.
In concave portions of paper with uneven surfaces (such as textured paper), the density of high-density images may be too light.
