I have had the MIS (sponge) cartridges, charged with UT7 inks, in my 
2200 for over a year and I print frequently enough that all 
cartridges have been refilled at least once and most of them several 
times.  I have not encountered the problem you describe.

May there be some distinction in your method of refilling versus mine 
that introduces air to the system?  To refill a cartridge, after 
removing it, I first tightly stretch electrician's tape over the 
output port to have an air-tight seal.  The dainty MIS refill hole 
plug has been replaced by a 6-32 Allen head screw.  It is removed and 
a small, spring-loaded, clamp is placed on the empty tank to compress 
it slightly.  After filling a syringe with the proper ink, I hold it 
with the needle up and eliminate any air by carefully pushing the 
piston.  The needle of the syringe is placed close to the tank bottom 
(with the cartridge upright) and the ink introduced with the needle 
end always under ink.  (Of course, I am careful not to let air re-
enter the needle and syringe.)  Except for the first cc of ink, which 
is delivered slowly, I quickly empty the syringe.

With the ink delivered, I replace the Allen head screw and place a 
bit of masking tape over the screw location to assure an air-tight 
closure.  The clamp is then removed causing, I believe, a reduction 
of air pressure in the cartridge.  The SK11 (?) is then applied to 
the chip so the machine will know that the cartridge is full.

I immediately replace the cartridge in the 2200 after removing the 
electrician's tape.  An immediate nozzle check and subsequent 
printing have always been normal.  I have never used cleaning cycles 
after filling.  I recall, some time ago, that one of the inks failed 
to print in a nozzle check (which I perform at least once a week) and 
cleaning corrected that problem with two or three cycles.
