Possible causes and solutions
Try reducing the print density. To adjust the print density,
press {Menu} on the control panel, and then select [Image
Density] from the Maintenance menu.
See p.92 "Adjusting Image
If "Add Toner XXX" (where "XXX" is a color) appears on the
display, replace the appropriate color toner cartridge.
See p.40 "Replacing the Toner
Make sure the toner cartridges and photoconductor unit are
installed correctly.
See p.40 "Replacing the Toner
See p.45 "Replacing the Photoconductor
Non-recommended paper is loaded. Use paper recommend-
ed by the supplier.
Make sure the machine is level.
See p.75 "Cleaning the DustProof
See p.75 "Cleaning the DustProof
Select [Text Priority] under [4C.Graphic Mode], and then print.
To set 4C.Graphic Mode, select [4C.Graphic Mode] from the
Maintenance menu.
Reduce the resolution, and then print. In the RPCS
driver [Change User Settings] dialog box, change the [Resolu-
tion:] setting on the [Image Adjustments] tab.
Try reducing the print density. It is recommended to reduce
the image density of black, cyan, magenta, and yellow equal-
ly, as this will preserve the color balance.
See p.92 "Adjusting Image
Make sure the side guides inside the paper tray are locked.
See p.20 "Loading Paper in Tray 1/2 and the optional paper
feed unit".
Make sure the lower left cover of the printer is properly
closed.
The paper orientation you selected may conflict with that se-
lected in the printer driver option setup. Make the settings
correctly.
If printing is not done in the specified color, restart the printer
by turning it off and back on, and then try printing again.
