5-18 Phaser 7750 Printer Service Manual
Streaks Parallel With the Leading Edge
There are dark lines running parallel
with the leading edge of the print,
perpendicular to direction of paper
travel (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, making
print artifacts parallel to the long
edge of the print.
B-size prints are processed through
the printer with the long edge of
the print parallel to the paper path,
making artifacts parallel to the
short axis of the print.
1. Inspect the paper that is loaded in the paper tray. Is the paper wrinkled, dimpled,
or show any signs of having a high moisture content?
2. Does the band repeat at a specific interval? If so, troubleshoot using the
“Repeating Defects Page”.
3. Run the Remove Print Smears routine. From the front panel’s Troubleshooting
Menu, select Print Quality Problems, then select Remove Print Smears.
4. If the engine test prints are all okay, but prints from an application or the image
processor board are not, replace the image processor board.
