I'm having the same issue as the OP. I went through the suggestions above; the nozzle check pattern came out looking fine, as far as I could tell, with all colors accounted for. But when I try to print from the computer, everything's still blank. Any suggestions?
Thanks,
Dan
P.S. Immediately prior to this issue, I was receiving error 6A80, which I resolved from the information elsewhere on this forum. Dunno is that informs the conversation at all...
