I just called Office Max at this Charleston location to find out if they refill ink cartridges (espec. my HP #61). The man who answered told me that ALL print makers have issued a warning that NONE of them will any longer allow used cartridges & that I should have already received that notice from H.P. I inquired "You mean H.P. & all other brands will reject a refilled cartridge?" And he said yes.
I then called Tech Mail and was told it is absolutely false & they've never heard of such a thing. And to bring in my HP/black ink & have it refilled for $8.00.
