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.

i forgot to ask you in the last post, does this happen only in copy or print or in both

Replace the drum unit & transfer roller WITH GENUINE CANON, I’ve tried the pirate drum & blades but they don’t last as long as the complete unit so it’s not worth the hassle.
