Just installed a new black cartridge, now I am getting a door open message but, it's not open.
You may have a broken cartridge lock or door sensor. remove all the toner cartridges. then open and close the door and watch for 4 white hooks that open and close on the right interior of the machine where the cartridges are installed. if three of the 4 open and close with door then the one that doesn't is your broken lock. if all 4 work then you have a broken door sensor. Good luck.
