so, i got so excited when i discovered i could re-fill my ink cartridges.. i was able to refill them maybe 3 times before having problems. I noticed i had to refill them more frequently and finally couldnt make it through 2 pages without my paper spitting out in light tones (not a full color print as thought the ink ran out). my prints always come out nice, but i finally discovered my ink was leaking from the cartridge into the inside of the printer. and the cartridges no longer held ink for a good amount of time.
my question is: is this just a fluke thing, or can cartridges only be re-filled a few times and then go bad?
I also read on another post that cutting a kitchen sponge and putting that under the cartidge where it locks in will tighten the conection, will this help my situation? ive noticed even with the stock cartridges the color always seems to seep out the sides a bit, it never leaks or splothes onto the photos, i just notice it when i remove the cartridge..
buying ink is killing my bank account! so i was stoked to find out about refilling it for a 1/6 of the price..
maybe i need to go with a continuous system instead? that scares me!

also, question #2. can i refill my stock ink cartridges with other types of ink? durabrites/or pigments (still learning about those, so sorry if i have the names/types wrong). ive only found "universal" ink kits.. but im sure there are better quality brands out there online..
please help, im on a roll and having so much fun with all this!
