Problem could be with the toner hopper on the front.

Make sure the back cover is on properly. There is a sensor in the bottom left corner that needs to be covered. If it isn't covered the only symptom seems to be a false message saying to add toner.

I'm interested in how this turned out, but sorry, I don't understand the answer. Can you re-phrase? =^..^=

just for another possible future solution, i remember in the toner hopper there is an arm (for toner level detection) with a magnet on it. the magnet used to get developer on it and weigh it down so it always looked for more toner.
although this instance may have been solved electronically, its another simple thing to check before replacing parts.
