Digital BW, The Print

Hello,

I purchased a set of Ultratone inks for my Epson C86. I'm having a
problem getting the inks flowing properly. Here's the history:

The factory ink cartridges worked just fine. When I first put in the
UT inks, however, I didn't get any ink on the paper whatsoever. I took
the cartridges out, shook them vigorously, and put them back in.
Nothing. I did it again, ran a set of three cleaning cycles, and I got
faint printing. A nozzle check printout showed that the black ink and
cyan position inks are printing intermittently. I put the factory inks
back in and had no problems printing.

I then searched on the net and read about the "water drop trick", that
the inks would start flowing if a drop of water were put inside. So I
removed the cartridges and did this. Thankfully, the black and yellow
slot cartridges have started to flow, albeit with gaps. (I'm using the
nozzle check printout to check this). The cyan and magenta slot
cartridges are still totally blank, no matter what I do. I've tried
cleaning a couple more times.  Now another problem has arisen. I can't
clean the nozzles anymore because the printer reports that the black
ink cartridge is low! I haven't printed more than a page with the
cartridge.

Someone please give me a hand -- I'm very frustrated.
