Roller-Width Soils At 143Mm From Paper Edge - Canon imageRUNNER ADVANCE 8105 Series Manual

Symptom

2 roller-width soils at 143mm from paper edge

[Manual-related]
Description
Soils corresponding to the width of the Registration Front Roller may occur at 143mm from the edge of the
paper.
Cause
The Duplex Unit has 4 Cleaning Brushes that contact with the Duplex Right Roller and the Duplex Outlet
Roller. Paper dust and toner accumulated in these brushes gradually attach to the surface of the
Registration Front Roller via fed paper. Then, when the paper stops at the Registration Roller due to
registration control, the rotating Registration Front Roller rubs the paper, so soils corresponding to the
roller width occur at 143mm from the edge of the paper.
