HP LaserJet Pro 400 color Printer M451dw
Microsoft Windows 10 (64-bit)

I have an HP LaserJet Pro 400 M451dw duplexing printer. It has been working great. It had a paper jam and someone forced the back door closed and a little white lever with a hole and a slide popped off a track in the back. I need the feeder assembly instructions so I can put it back where it goes and get the printer operational again.

If you search on the internet you should be able to find a service manual for that device that may contain a diagram, or you could post a photo of your issue and someone may be able to guide you.
