You haven't said how old the drum is either...how many copies?

[welshman]

another thing to check is the blank exposure lamps all working they provide blank lead edge

also check the blank lead edge setting if set to nothing the toner will foul up the charge roller transfer roller etc etc

other than that the drum unit transfer roller and is it genuine canon toner or katun toner

Have you replace the spacer roller, as spacer roller may deformed after machine run above 250k.

It start happen during copying process. After that it happen to all, it always dirty at one side only as per photo attach. But the density of dirty become darker from beginning.
