HP F4280 I have what I believe the printer door open,on the front of machine above paper feed. Printer is ON with the ink amount blinking orange for the color cartridge and an "E" at the "start" copy. Am unable to print anything. Believe color cartridge needs changed, but don't have the manual at hand.
