Dark edges on both sides since a couple of days on my CDW8380

[Johncoffee]

Since a couple of days I found my CDW8380 printing out pages with dark edges on both sides of the paper. Nothing had changed recently, I'm using the same toner & paper as always. The left side seems to repeat every inch while the right side has some vertical band.

Tried both cleaning steps (transfer belt and fixing unit) to no avail.

Thanks for any suggestion.

Best

This is how a empty page print out looks like:
