How do the print outs look?
Usually with toner it starts to get less viable, but that error is a toner error. You can try taking the current toner out and shaking it....old IT trick, but on the other hand that can be messy. I would advise to buy new toner and go from there. Even if your shook it up enough to work, that error will remain until its replaced.
Make any sense?
