Hello Printer Experts,

I hope that you can help me. My E525w has just started printing with a dark stripe down the page, always in the same place, sometimes darker than others. I have not recently changed any cartridges.

I have tried removing the cartridges and cleaning inside with the cleaning stick - no difference. I have peered inside the back and can see a vague toner stripe on the roller, which I tried to wipe off but to no avail.

I'd be grateful of any help at all (I'm a bit of a printer dummy!).

Many thanks.
