Streaks In Direction Of Paper Travel - Xerox 7700DX - Phaser Color Laser Printer Service Manual

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 -- making
horizontal print artifacts
parallel to the shot 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
horizontal artifacts parallel to
the long axis of the print.
1. Check the end of life for each of the consumables by printing the supplies
usage page. From the front panel's Printable Pages Menu, select Print
Supplies Page.
2. Run the solid fill test pages. From the front panel's Printable Pages Menu,
select Service Pages, then select Print Solid Fill Pages. If the missing
bands only occur in a single primary color, replace the print cartridge of the
affected color.
3. Swap print cartridges 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.
4. Inspect the Accumulator Belt cleaner, replace the cleaner, if necessary.
5. Run the Remove Print Smears routine. From the front panel's Support
Menu, select Improve Print-Quality?, then select Remove Print Smears.
6. Replace the Developer Housing Assembly (RRP 27, on page 7-185).

edge of the developer housing.
