Digital BW, The Print

Ok,
I guess this has been discussed somewhere & I just missed it.  The 
obvious things are what I sometimes overlook.
I have been printing using Roy's Quad Tone on a PC for sometime with
no 
issues and very pleasant results.  I have been disapointed however
with 
the warm tone of the EOM inks, so I purchased the MIS Eboni Black-POS 
#UT7-T0348-K.
I installed the cartridge and the Epson 2200 does not recognize the 
cartridge and refuses to print.  I can put the Epson cartridge back
in 
and it works fine.  What am I doing wrong?
