Print-Quality Troubleshooting 5-17
Streaks in Direction of Paper Travel
There are dark lines running along the
page in the direction of paper travel
from the leading edge to the trailing
edge (B-size print shown). The printer
displays no error code.
Note
A-size prints are processed
through the printer with the short
edge of the print parallel to the
direction of the paper path.
B-size prints are processed through
the printer with the long edge of
the print parallel to the paper path,
making horizontal artifacts parallel
to the long axis of the print.
1. Run the solid fill test pages: From
the front panel’s
Troubleshooting Menu , select
Print Quality Problems , then select Solid Fill Pages . If the missing bands
only occur in a single primary color, replace the imaging unit of the affected
color or, swap imaging units and run another test print.
Note
Under some circumstances, streaking may occur in the margin of SRA3-size
paper. This is due to the edges of the paper extending beyond the end of the
imaging components. Print-quality in the margins of SRA3 paper is not
guaranteed.
2.
Print the repeating defects page, do the lines/streaks align with any of the
repeating defect marks?
3. Inspect the accumulator belt cleaner; replace the cleaner, if necessary.
4. Replace the developer housing assembly, if the defect is in one color only.
5. Run the Remove Print Smears routine. If the defect returns, replace the fuser.
