That sounds like a good idea to me, can you explain in more detail how you drain and then top off the newer one's. What is the process and how do you actually fill the newer carts?
Thanks fro this great idea!
For cartridge machines without chips.. First off weigh your brand new cartridges with a gram kitchen scale. You'll weigh the empties as well. The difference is the volume of ink inside in milliliters. I track my cartridges by weighing them every so often and charting it on a cartridge weight record. Makes reordering time easy.
Once your new cartridge is down by 50cc or so, you can refill. I usually wait till 100cc tho.
I use a 50cc cattle syringe from enasco.com (part #C25633N) with a 16ga leurlock needle (part # C29520N) attached, I grind the needle to be flush so it doesn't prick the ink bag, based on btdt experience!. the heavy duty vet syringe is needed so you can get a good grip to pull the ink out of the bag. I up end the cartridge so the ink port is down, insert the blunted needle, feel for the seal to give way, and then draw the ink out 50 cc at a time.
Reverse the process by putting new cartridge port up, insert needle, push ink into cartridge. When done with ink transfer, pull some suction on the new cartridge to remove any air you might have added.
So long as you don't exceed the original cartridge weight you should be fine. I've been doing this for 8 years after we abandoned a junky bulk ink setup that was horrible.
And Yes you can buy bulk ink by liter or even gallon and save. You can get ink costs down to $0.06 PSF that way with 220% cover.
Takes about 5 minutes to refill a 440ml once experienced.
If you have a machine that reads the chip based on nozzle firing, go online and buy a chip resetter.
