I believe the "relay Unit" on that machine is the section that transports copies to either the finisher (if installed) or the exit tray on the LEFT side of that machine. Sometimes neither of these units are present, but the relay unit may still be installed.
There are 2 flip up covers on that section (left and right), and you will probably see that one of them (usually the left one) has come unclipped, or perhaps the plastic clip that holds it closed is broken. If you flip up this unit. You will see a black button at the back end that is engaged when ther unit is closed. If you simply pree this button with your finger, hopefully the message will go away - this may at least help you troubleshoot what is causing the "cover open" message). Even if the clip is broken, it is often just a matter of seating the unit correctly so that the switch is engaged when the unit is closed. There is also the same switch on the right cover that could be causing the problem, but this cover doesn't sem to get damged as often.
I hope this helps. Please let me know.
