Secondary Transfer Roller Position Settings
You can switch the position of the secondary transfer roller to either a image quality priority position where image quality improvement can be expected or a thin paper position for jam reduction.
1
Press <Change> in <Sec. Transfer Roller Pos. Settings>.
2
Select a priority position of the secondary transfer roller position.
You can switch the position of the secondary transfer roller to <Image Quality Priority> (the image quality priority position) where image quality improvement can be expected. You can also switch the position to <Jam Reduction Priority> (the thin paper position for jam reduction) where a paper jam due to imperfect paper separation can be improved.
<Auto (Speed Priority)>: This is the default setting.
<Image Quality Priority>: This setting is expected to reduce uneven densities that scratch the toner image in the entire halftone image or horizontal streaks of uneven densities at the front or rear end.
<Jam Reduction Priority>: This setting is expected to reduce paper jams that occur at the secondary transfer roller.
If you select <Image Quality Priority>, a paper jam may occur.
If the image quality is not sufficiently improved even after selecting <Image Quality Priority>, the image quality may be improved by adjusting a paper conveyance support plate.
If you select <Auto (Speed Priority)>, paper with a basis weight of 67 lb cover (181 g/m2) or more may operate in <Image Quality Priority> (image quality priority position).
If a paper jam occurs in the secondary transfer roller when the paper is set to a basis weight of 67 lb cover (181 g/m2) or more, it may be improved by setting <Jam Reduction Priority>.
If a paper jam occurs in the secondary transfer roller when the paper is set to a basis weight of 67 lb cover (181 g/m2) or more, it may be improved by setting <Jam Reduction Priority>.
If you specify <Jam Reduction Priority>, uneven densities may occur.

If <Image Quality Priority> is specified, <Adjust Paper Conveyance Support Plate> can be performed.
When you specified the <+> direction:
If there are horizontal streaks of uneven densities at the front or rear end of the halftone image, the image quality may be improved.
If there are horizontal streaks of uneven densities at the front or rear end of the halftone image, the image quality may be improved.
When you specified the <-> direction:
If there are uneven densities that scratch the toner image in the entire halftone image, the image quality may be improved.
If there are uneven densities that scratch the toner image in the entire halftone image, the image quality may be improved.
