So I just picked up my Z3100 (24") and started running through the print setup. Installed the inks, installed the heads. going, going... "LM Faulty" K.... Well, try reinserting.. "LM Faulty." OK. Maybe the cartridge is bad? I bought a twin pack of inks with the printer, break open LM and it starts doing it's thing. I come back down about 30 minutes later to check on the printer and I get "LM near replacement" or something like that. WTF? So I pop it out and back in. "LM Faulty."
Of course, HP phone support is 5AM-5PM PST, which blows. So now I have to wait till tomorrow to see if they can help? This is just annoying.
