1.1.1.6.7 Image failure due to lines on Fixing Belt (luster streaks/patches of uneven gloss)/How to refresh Fixing Belt
0031-6904
[ Manual-related ]
Description
When paper with a longer width is used after copying or printing 100 or more sheets of paper with a shorter width (for example, when A3 paper is used after A4R
paper), luster streak may appear on both edges in the feeding direction.
Field Remedy
If image failures by lines (streaks and patches of uneven gloss) on the Fixing Belt occurred, these symptoms may be reduced by performing the following service
mode and refreshing the Fixing Belt.
- Service Mode > COPIER > Function > CLEANING > FXD-CL-E
[Caution]
- There is the automatic refresh control for the Fixing Belt to prevent luster streaks but this mode should be executed if luster streaks still occur.
- Be sure not to execute this mode frequently as this will reduce the life of Fixing Belt.
[Reference]
If the user performs the Refresh Fixing Belt, select and execute from Settings/Registration > Adjustment/Maintenance > Maintenance > "Refresh Fixing Belt".
Refresh Fixing Belt takes approximately 120 seconds.
