HP8150Duplexing

[pdewb]

8150 prints fine in single mode, but Duplex leaves a black streak on the backside page rightmost edge, almost on the side (as if you had flipped a stack of paper on edge and painted the edge lengthwise (11"). I have installed a maintenance kit and a new duplexer. Any ideas?

You tried a different toner?

I had the same problem on a 8150DTN last week. As Steve said, it was the toner (turns out that they had installed a refurb from an office supply place). I replaced it with an HP toner and all was well.
