What is causing this blue line on my color laser printout?

[rpeters83]

Brother HL-L8350CDW laser color printer. I see this in some color photos. The toner is fairly new. What could cause the blue vertical line? It usually appears in the same spot on different photos. Thanks.

Thanks. Is this something I can clean? It's fairly new and the drum still has 83% life, according to the info page.

I’ve never had success but I am all thumbs - ymmv. I’d try a warranty claim if it’s new enough.

Late but a clean lint free soft cloth with isopropyl alcohol can usually clean a laser printer drum. Could also be something on the image transfer belt.

I was able to resolve this for free. Turned out to be a dirty corona wire. My printer has a little "slider" that is used to clean it. A few swipes and the line is completely gone. Thanks!
