Insufficient Fusing
Phenomenon
Printed image is partially missing as shown in print sample [23] of Fig.9-1. This proves that the
fusing is insufficient.
Main Causes
(1) The fuser tension-release lever is open. The shipping pieces are not removed.
(2) Wrong selection of print media (label or envelope, etc.) at the host (driver) side.
(3) Recommended paper is not being used.
(4) Failure of the fusing unit.
Countermeasures
(1) Return the fuser tension-release lever. Remove the shipping pieces.
(2) Adjust the mode of host side to suit the print media in use.
(3) Use the recommended paper.
(4) Replace the failed fusing unit with a new one.
