That's an HP printer, and 50% of that printers smarts are in the cartridge.  
If that is _not_ a genuine HP cartridge, and some of the re-builders are 
getting downright cute with their packaging, then its possible the cartridge 
is bad, particularly if they had to hack the cartridges fill state stuff in 
order to reset the empty status in it.

If you think its a genuine cartridge, I might try removing and re-installing 
it, washing the contact faces with a q-tip dampened in real alcohol just in 
case a fingerprint is getting in the way.  When I say real alcohol, the drug 
stores 'rubbing' isn't what I had in mind, the lumberyards & paint stores 
sell the real stuff.
