Digital BW, The Print

I installed the Septone system on my Epson 2200 on thursday night. 
After I inserted the cartridges, I ran 2 cleaning cycles. I couldn't 
get a good nozzle check, actually there was no ink coming out from 
the LK, M, C and LC nozzles at all. I know that the cartridges do 
not have the value inside(OEM Epson 2200 cartridge has value inside, 
so no air an go into cartridge from the bottom opening), there could 
be air bubble inside the cartridge. So I decided to print the flush 
image provided in the software CD, then the major problem came. The 
print head started spitting blob of inks on the paper and the black 
plastic area inside the printer. After the print is done(with blob 
of ink all over the print), I turned off the printer. On Friday 
morning, I called the customer support of inkjetgoodie. They said 
there shouldn't be any problem on the cartridges, only the first 
batch of the cartridges they sent out had problem and those 
cartridges I got are not from the first batch. They suggested me to 
let it rest for a while and test it again. Call them back on monday 
if problem still occurs. I try it on Friday night again(alomost 24 
hr after the first try, the air bubbles should have already 
dispersed), still, I couldn't get a good check(can't even get 50% 
percent of the nozzles working). I let it rest overnight, and try it 
again this afternoon. Still couldn't get a good nozzle check and the 
leak came again. I try to print the flush image, the print head spit 
blob of inks on the paper again. When it was printing, I can see 
there was a little pool of ink on the sponge(which rest on the print 
head when it is not working, to keep the print head from drying 
out). Lots of ink was lost because of this. Finally, I pulled out 
the cartridges and used the scotch tape to seal the bottom opening. 
I replaced the cartridges with the OEM Epson cartriges and 
everything works perfectly fine(no leak, no spit, perfect nozzle 
check). My 2200 works perfectly fine before and after I put in the 
Septone system, so I believe the problem is from the cartridges.

I will call inkjetgoodie again on monday to see if they have any 
solution for this. Frankly, I am quite disappointed with the result 
I got from these cartridges. 

Does anyone know why there was leak and spit from the print head? I 
used to have this problem on the MIS CFS on my Epson 1200 because 
the Siphon break was lost. But the Septone system I installed is not 
CFS.

Thanks
