Most C0900 range codes and specifically the 990 code refers to paper tray lifting. Pull out the paper drawers and check all the paper. Reload all the trays carefully. Then open/close the front door or turn off/on the machine to reset. If the code goes away great. If not then open all of the paper drawers, reset the code with the drawers OPEN. Then close each drawer 1 at a time waiting 30 seconds between each drawer closing. Once you close a drawer the code will come up within about 10 seconds. This will tell you which drawer is causing the issue. You can leave it out a bit so you can use the machine until you either find the issue with the tray or get a service guy out to fix it.
Good Luck

If you did not get ALL the jammed sheet out, there is still a small piece of paper in there somewhere, probably covering a sensor or micro switch. Get a torch and look carefully. If you don't find anything you may need to disassemble the printer to find it.
