HP Office Jet Pro 6978

 

I changed all my ink cartridges, black and color.  Now I have a Cartridge Problem.  I have followed all the HP suggestions, unplug the printer, turn it off, etc. and the error will not clear and the printer will not print.  My ink cartridges are all HP 902.  I also cleaned the print head. Help!
