Question about Xerox Phaser 8400 Laser Printer
My Phaser 8400 seems to detect a paper jam. The message is "Paper Jam - Open front cover to clear." I have opened everything on this machine that appears to be accessible, removed the paper tray and checked all the visible areas of the paper path and cannot find any paper. I'm thinking that a sensor may be causing the problem but, if so, I'm not sure how to resolve it.
Here is the Xerox support page for your printer. It even has a movie on removing paper jams.

This seems to be fault in the transport of the paper in the rollers. So if you have used any adhesive sticker printing, it is possible that some glue has got clogged into the rollers. If not there can be some jammed paper in the rollers or the mechanism.
So start this work only if you are mechanically able with the right tools.
Remove the covers to get access to the mechanism . Remove the motor drive assembly , the fitting of the motor to the mechanism. Once this is removed the rollers can be turned manually so that you will be able to feed a paper to see the progress of the movement while studying if there is any obstruction or damage to the paper.
There is a in-detect sensor, usually an opto-coupler , make sure this is not clogged or dirty as this IR detection feeds the signal to the processor for starting the motor drive feed.
Reassemble but make sure the rollers are aligned to be in equal gap to feed the paper without a side pull. Now you must print and see if the fault has changed. If not repeat the above work to confirm the area of obstruction.

If you receive an "Open front cover" error message the solution is to open the cover and remove the paper and any remnants of the paper jam. If there is no obvious paper remnants jamming the printer and you continue to receive an error message I would suggest unplugging the printer from the power source.
After 5 - 10 minutes plug in to power source.
Turn on printer.
See if this has resolved error message. If not you will need to check more carefully for paper remnants that would be causing the printer to detect a jam.
Trust this is helpful. :)
