How to drain IJM 3880 carts?
2015-09-24 by jeff.grant@...
Having changed to an R2000, I now have a set of 3880 carts with K7 ink in them. You can't drain them from the fill hole as it is in the middle of the back of the cart and baffled. I then tried draining from the nozzle. That worked to start but then doesn't want to let more ink out.
Other than tearing the carts apart, is there a simple way to do it? I'd like to salvage what's in there if I can.
