Toner Out Of Ink Already?

Try removing the toner/cartridge, put it back in and restart the printer (i.e. power off). If that doesn't work, try going into diagnostic mode and see if it will print. If it does, it's an issue between the printer and the cartridge. I'd get in touch with the place where you bought the toner and see if they'll exchange it, regardless.
 
If this was a brand new printer I'd say that you have enjoyed the pleasure of the "demo" starter pack toner syndrome. Printer manufacturers somehow imagine that shaving the original purchase price by the cost of a few ounces of toner makes up for enraging the customer who has to replace the cartridges with puzzling rapidity.
