Getting Fingers Dirty
Go to your nearest stores (Officeworks in Australia) that have recycle bins for empty cartridges and scavenge thru the bin don't worry about pride, think of the saving. The empty cartridges that I got were a bit on the dry side so I used a modified German method by drilling the hole half way up the face and using a modified syringe with a 50mm needle adapted onto a garden hose with heatshrink tubing (internal glue type), then hose out the residual ink (almost like reverse liposuction) when finished run a couple of syringes of distilled water through the sponge, then with a small air compressor use the drilled hole to blow out any remaining water from the sponge. With a 50mm needle the tank port can be reached to refill with ink. This method is best done outside to keep sweet with the Cook.
