I just bought this a couple of months ago. The cartridge that came with it ran out after just a couple hundred copies. I received a new one today and installed it but the toner indicator light remains on and, of course, I cannot print. The printer window says the printer "may be out of toner." It is not. I've removed it and re-installed it. I've unplugged and restarted the machine. No joy. Now what?
