Problem Sample Cause Solution
Smeared toner or water-like
marks.
Randomly-shaped smears that
meander, but are mostly in the
feed direction. The smears
resemble a mark made by water
droplets. They might be described
as looking like a snail or slug mark
on the page.
Printing in a high temperature/
high humidity environment and/
or with paper which has been
exposed to a high temperature/
high humidity environment.
Paper acclimated to this type of
environment has a high
moisture content, which can
cause the paper to curl as it
enters the fuser.
NOTE: This is a color example
of this defect. The defect can
also effect mono print jobs.
Replace the paper with a unopened
package of paper that is acclimated to
the environment where the product is
operating.
Printing the job using different paper
(75 g/m
2
or heavier).
If the error persists, the product might
need to be moved to an area of lower
temperature/humidity.
Smeared toner on leading edge.
NOTE: Orientation of the marks
depends on which way the page
travels through the paper path.
In this example, the long edge of
the page is the leading edge.
A portion of the toner on the
leading edge of the page is
transferred closer to the leading
edge.
The defect might occur in only
small areas, but happens when
heavy amount of toner are placed
very near the leading edge of the
page.
NOTE: This is a color example of
this defect. The defect can also
effect mono print jobs.
This defect is associated with
the media slapping against the
ITB blade at secondary (T2)
transfer.
This typically happens when
printing from Tray 1, but can
also happen from trays 2-5.
TIP: This defect is more
prevalent when using heavy
paper.
If printing from Tray 1, try using a
different tray.
Use a different, lighter weight paper.
Use the print driver to increase the
margins on the page.
