Repeating Print Defects On Print - Xerox Phaser 8400 Service Manual

Repeating Print Defects on Print

Step Question and Actions
1 Repeating defect 11.6 cm (4.58 in.) are caused by the Transfix Roller. Clean the
Transfix Roller. Defect does not move in X-position.
2 If the problem persists, replace the Transfix Roller.
3 A single repeating defect on the page with the defect on each page having a different
Y-axis position is probably due to a defect on the Drum.
4 Rotational position of the drum changes every print. If a single defect appears on
multiple solid fill pages and is always in the same X-position, clean or replace the
Drum Assembly.
Print-Quality Troubleshooting
The distance between each artifact of
a repeating image defect reveals
which imaging component is causing
the defect. Transfix Roller defects will
show up as light spots in solid fill
areas.
