Faint white line on a second side image due to the stain on the
Connection Lower Guide Roller for the Primary Fixing Assembly
[Symptom]
A faint white line [a] might appear on a second side image, if the machine is used a lot under the high temperature and high
humidity environment.
The arrow [b] indicates the direction of feeding.
The symptom is easily found on a high density image such as halftone or solid image.
[Cause]
IF the paper having a lot of paper lint is used under high temperature and high humidity environment, the paper lint and wax
component of toner combine and adhere to the Connection Lower Guide Roller [1] located at the outlet for the Primary Fixing
Assembly.
When the paper lint and the wax component of toner which adhere to the roller are transferred to a paper, the above symptom
occurs.
[Service work]
1) Open the Sub Station Front Right Cover to pull out the Primary Fixing Assembly.
2) Clean the whole surface of the Connection Lower Guide Roller with lint-free paper moistened with alcohol rotating the roller
by hand.
3) Output the image having shown the symptom, and check that the symptom does not occur.
If the symptom does not improve, then check other factors.
