imageCLASS MF455dw - Duplex copying results in blacked out image

[hsief4609]

We are having issues with our Image Class MF455dw copier/printer and it's ability to copy duplex print jobs.  The 2nd page always comes out with half the copied page black.

I've tried resetting the printer to factory default, but that didn't help.

The printer is maybe 2-3 years old.

Thank you in advance for your suggestions!
