Digital BW, The Print

OK well for what it's worth the spongeless 21/2200 carts I've been using
don't have any issues with ink leaking out into the printer.  They have two
holes in the top that come shipped with plugs in them.  The stopper for the
primary filling chamber is replaced once the cartridge is full.  The second
stopper over the hole at the top of the spill chamber where air comes in
remains out (and can act as a spare if you lose the one for the filling
chamber).  The carts are certainly considerably more sophisticated than the
MIS ones but not as complicated as Epson's.  I prime them with an MIS bottom
fill adaptor when they are brand new - it's not necessary to do this when
refilling.  I have noticed some drops of ink coming out the poppet valve on
some carts when refilling if the poppet valve is not properly sealed when
the cartridge is out of the printer.  This just requires some monitoring and
is easily corrected when noticed.  Of course the poppet valve is depressed
when they're in the printer.  I'm very happy with these cartridges and would
never want to go back to the MIS sponge ones.
