Problem Sample Cause Solution
Smeared toner (in the feed
direction).
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 image is smeared
in the feed direction. The section
that is smeared may be a narrow
or wide streak, but is smeared
from leading to trailing edge of
the page.
NOTE: This is a color example of
this defect. The defect can also
effect mono print jobs.
TIP: The customer might
describe the image as blurred.
The mylar strip near the
secondary transfer (T2) area of
the ITB is out of place and
dragging across the toner on
the ITB.
This occurs more commonly
after a paper jam, or the first
printing in a high-temperature/
high-humidity environment.
NOTE: o Torn edges of paper
caught in the ITB blade after a
paper jam can cause this defect.
1. 1. Print the PQ Troubleshooting
pages to ensure the issue occurs
across all color planes.
2. If the defect started after a
paper jam, check the ITB for torn
pieces of paper.
3. Print approximately 10 pages to
see if the smear goes away.
4. If the error persists, replace the
ITB.
Shifted or cut-off scans (M680).
Images copied or scanned are
shifted, in some case the shift
might be enough for part of the
image to be cut off. In this
example, the image at the top of
the page is missing.
NOTE: This is a color example of
this defect. The defect can also
effect mono print jobs.
The document feeder guides
are not set correctly, pressed
against the original.
Make sure that the side guides are
correctly set against the page.
If the error persists and the defect is
isolated to the document feeder,
replace the document feeder.
The scanner needs to be
calibrated.
1. From the Home screen on the
control panel, scroll to and touch
the Device Maintenance button.
2. Open the following menus:
●
Calibration/Cleaning
●
Calibrate Scanner
3. Touch the Next button to start
the calibration process. Follow
the on-screen prompts.
4. Wait while the product calibrates
the scanner.
5. If the error persists and the
defect is isolated to the scanner,
replace the scanner.
