Digital BW, The Print

I'm relatively new to refilling my 2200 cartridges (MIS Pro), having done
around a half dozen cartridges so far. I just tried to fill 3 more and the
first is fine but last two did not work. My chip resetter (SK168-II) flashes
a few times and then turns solid red when I try to reset chips now. The
printer of course will not start up, showing errors on the last two
cartridges that would not reset.

Do I have a bad chip resetter? Any tricks or workarounds?

Thanks,

Terry.
