What steps may I take to >find out what has gone wrong with my setup? 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. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
