My printer has the LED for the three color cartridges blinking along with the Alert LED.  The Black cartridge LED is not blinking.  These three cartridges did this at the exact same time.  I am wondering what the changes are of all three running out of toner at the exact same moment is.  My concern is that there is a more serious problem with the printer that will not be solved by just replacing the three color cartridges and I will have wasted money buying them.
