Canon imagePRESS C10000VPSeries - Uneven Density in a Grid Pattern on a High Density Image Due to the Uneven Resistance on ITB

Uneven density in a grid pattern on a high density image due to
the uneven resistance on ITB
[Symptom]
When printing a high density image on a device having high operation rate, uneven density [a] may occur in a grid pattern.
More visible on green and red high density images.
The arrow [b] indicates the direction of feeding.
[Cause]
As the number of pages printed on the ITB grows, the electric resistance on the ITB becomes uneven causing the density of the
transferred image to be uneven. As a result, the above symptom occurs.
