Single color mottled or with non-uniform density streaks
If a single color displays a mottled
appearance or if a single color shows
many vertical streaks of varying densities,
then that color’s toner cartridge is running
of toner. Replace the cartridge.
Dark vertical line in print, single color
If the line is of one primary color, then the
trouble can usually be traced to a defect in
the color’s toner cartridge. Too much
toner is transferred from the developer
roller to the photoconductive belt at the
defect point.
Vertical line in print, all colors
The problem may be caused by a dirty
main charger, a defect in the fuser or a
defect in the imaging unit.
