Xerox Phaser 7700 Service Manual page 134

Residual image or ghosting
There are faint, ghostly images
appearing on the page. The images
may be either from a previous page or
from the page currently being printed.
The printer displays no error code.
1. Make sure that the paper you are
using is the correct type for the
printer and is correctly loaded in
the printer. From the front panel's
Printable Pages Menu, select Print
Paper Tips Page.
2. Make sure that the paper loaded in
the tray matches the paper type
selected on the printer's front
panel.
3. If the problem continues, set the
paper type in the front panel to the
next heaviest type of paper than
what you are using. Below is a list
of paper types from the heaviest
weight to the lightest:
Thick Cover/Index
Thin Cover/Index
Heavy Laser Paper
Laser Paper
4. If the colors are offset by only a small amount (10 mm maximum), then
calibration of the laser may be needed. This is mis-registration, not ghosting.
Go to Mis-registration on page 3-110.
5.
If the ghost is offset by more than 84 mm, run the Print Smears routine to clean
the fuser. From the front panel's Support Menu, select Improve
Print-Quality?, then select Remove Print Smears.
6.
Inspect and replace the Fuser if necessary (RRP 19, on page 7-160).
Note Some ghosting may appear on transparency film printing and is a limitation of the
printer.
