Check the total page count in the menu. If it reads 288888, you have a defective engine board and it needs to be replaced. It is neither a driver issue nor a problem with the paper cartridge.

Brother will quote you a price in excess of $600 for a new engine board, but some authorized repair shops can get them for less than $200.

MFC9420CN brother printer says Check tray #1 Reinstall tray

I had this same problem. The solution was resetting it, and the instructions below worked for me:
2.3 Parts Life Reset Function

This function is provided for service personnel in order to reset the counter of each periodical replacement part and count the number of replacement times when replacing the periodical replacement parts.

(1) Press the 3 and 9 buttons at the same time in the ready

(2) The "Reset Menu" will appear on the LCD. Select the
applicable periodical replacement part by pressing the up arrow or down arrow button and press the OK button.

- Drum - Belt Unit - PF KitMP - PF Kit1
- PF Kit2 - Fuser - Laser

(3) When the OK button is pressed the "1. Reset 2. Exit"
appears on the LCD. Press the 1 button if resetting the
counter. If not, press the 2 button.

(4) Pressing the 1 button accepts that the machine implements
the counter reset.

(5) If the 2 button is pressed the machine goes back to the
select part counter again. If you need to Exit press the
Stop/Exit button at any time.

(6) The machine returns to the ready status.

    Re install tray will not clear

    OK, we never found a battery locally, but we tried something else. WE removed the battery and left it out for several hours. Our thinking was we were trying to reset the memory somehow. Well, it worked. We put the same battery back in hours later and the check tray msg. went away. The printer still works fine almost 24 hours later.
