There is a gray button right of the LCD display that has a black arrow circling clockwise and four color dots (magenta/black/cyan/yellow). Push it until you see the "Rotating to Yellow" in the LCD display, then open up the top of the printer by pushing the big gray latch next to the picture card reader at the right front of the printer. You now have access to the cartridge. pull it out and examine it. If it is a new cartridge, check to see if you pulled the plastic dam strip out (which keeps the toner in place in shipment etc).

The OEM cartridges have a chip on them. If the aftermarket supplies do not have the right chip, missing a chip, etc., the machine will not recognize. Placing the old cartridge back in without any toner can give off the same message.
Try rebooting the printer without a cartridge in. Then install the cartridge, either one, and see if that helps. If not, wait for the OEM to arrive.
