>>This not an option, of course, for the third-party refillable cartridges,
since they do not use ink pouches. (In my experience they are also more
likely to experience leaky valves, too.)

 

Myron,

 

Actually there are empty carts with Mylar pouches for the 4880, from MIS
that work very well, including the 7800/7880 carts which are pressurized.
They're $18 each and are filled/refilled with the 60mm syringes and
tip-adaptor. I've used them in my 4880 and 7800s for a long time without any
significant issues (other than a few chip reading blips). The spring-valves
are pretty robust and I've pulled and switched some of mine at least 20-30
times. I prefer these type of carts over funnel fills because the bags don't
expose the ink to any air. I don't have any comparative life data, but
keeping the inks from an oxidizing/evaporative environment can only help.
Some of the inks have been in the printer with pouch carts for over a year
and are as good as new. I really wouldn't worry too much about pulling the
carts for agitation occasionally (though the peep-hole for agitating the bag
is an interesting idea). 

 

Best,

 

Tom
