I was searching for this condition, I just purchase a B210 printer, and uit's doing the samething. It's not jamming, it's like the printer gets confused when it bring the page back in to print the other side
I've reloaded the driver, same issue. Tried a new package of paper, same issue
I searched our online knowledgebase and found this article for Jams in the Duplex Module Area that may help you rectify this issue.
Just bought the B210. When I try to do double sided printing, the paper sticks when it is being pulled back through for the second side. It does this every time. Is this a fault with the printer or something to do with the printer drivers?
