Parallel Streaks in the Paper Feed Direction
During a consecutive paper passage with an identical size of paper the edge of paper contacts a part of the fixing
belt surface. This makes the part rough and leads to the relevant symptom. As this symptom might be a
recoverable case, perform the following work referring to the section "Glossy streaks appears in parallel to the
paper feed direction" of p.122 " Tips and hints for better print " before replacing the fixing belt unit or pressure
belt unit.
1) Refresh the Fixing Belt from (Settings/Registration) > [Adjustment/Maintenance] > [Maintenance] >
[Refresh Fixing Belt].
2) After the operation has completed, execute printing again. If the effect is insufficient, perform the
Refresh of the Fixing Belt again.
3) If an improvement is observed in the aforementioned steps, the frequency of performing the Refresh
Operation may not be sufficient. In this case, change the frequency of execution for refresh referring to
"Cut on the fixing belt by the edge of paper" in Situation Mode.

NOTE:
If the pollution on the surface of the Refresh Roller progresses after some endurance time
has elapsed, the effect might not be exerted adequately. In that case, execute Cleaning of
the Refresh Roller Surface referring to "Parts replacement - Cleaning procedure > Fixing
system > Fixing refresh roller cleaning" in the imagePRESS C800 Series Service Manual.
