Digital BW, The Print

Hi all,

I just received some new UTBO Eboni for  the R1800 3mk set-up. I have not ordered anything from them in awhile and I notice their cartridges look a little different. There is no longer a small tab to remove....at least I don't see one. And no ink is coming out of of either the mk or pk position AT ALL, even after a shake and a head cleaning.

What am I missing??

Thank you,
Sarah
