"Milky" Appearance on Paper

Problem Description:
The defects are created when the toner melts and moves prior to pressure in the fuser. This movement
exposes the media color under the toner and creates a light, "milky" appearance on the media (see
picture below).
Most Likely Cause:
The defects happen in high humidity environments when the edges of the media become saturated with
moisture while the center stays dry. This creates waviness (or rippling) in the edges of the media which
cause the paper to enter the fuser unevenly.
Resolution:
•
Try a new ream of paper (that has never been opened) in the Tray.
•
Check the media settings in the printer and verify they are correct for the paper type/weight
used.
•
Flip the paper in the Tray so the rippled edge enters the printer last.
•
Instruct the customer to keep media out of any direct airflow from an air handling vent.
Explain to the customer that media absorbs moisture which causes the print defects.
•
Suggest they store unused media in an air tight container to keep it dry until needed.
•
If the customer is using 16lb media for duplex, recommend a heavier media to use (20 or
24lb).
•
If none of these suggestions work, try replacing the fuser.
