I have a MF726Cdw that passes the paper through from the tray to the output without any issues at all showing a Device Paper Jam 5. This is happening at power on automatically without a computer or any other source connected to the printer.
I have checked repeatedly for a jam anywhere and there is nothing in the paper path.
Not sure of the next step is to resolve it.
I did a little more work with it and I cannot get past the Device Paper Jam 5 at power on. When powered on the printer feeds a sheet of paper to the output tray from the paper tray and throws the error. If you follow the error instructiona and clear the jam it will feed another sheet of paper and throw the error again.
I attempted to use the maintenance menu to have the system do a cleaning but it will not start the process because it still have the paper jam error active.

If the printer feeds a blank sheet through and then switches to a paper jam issue, it looks like the printer needs service. In this situation, you can try reseating the toner using the steps in the link found HERE. If you do not see any obstructions that you can move and you still have the same issue, it would mean the printer needs service.
