It's dead, Jim.
It just boots up now to a display system error and it doesn't clear with a power cycle like it instructs.
It has a bad document feeder, needs toner, the paper paths are contaminated with spilled waste toner and now it has a new problem. At this point take the paper out of the drawers and push it into a dumpster because right now it's doubling as a very large scanner and to get it completely repaired is worth more than finding another color all-in-one photocopier.
