There is a local business that does this already! You can bring all your old cartridges there and maybe they'll give you a discount for being a local nonprofit! And because your old cartridges are valuable and will be reused by them:

Hi Sudoroom,

I'm writing from the Long Haul in Berkeley, a space kinda similar to the Omni.

We are quickly accumulating a bunch of half full ink tubes which our printer decides are empty based on reading/writing the RFID chip on the tube. Its calculated based on the number of pumps. The machine is a Riso RZ990.

I am wondering if anybody at Sudo is interested to collaborate on keeping these tubes out of the landfill by re-writing the RFID chips to show a full tube? Maybe this is something to drop by Hardware hack night on?

(In the longer term we hope to fix the machine to avoid this problem in the first place. Come visit us sometime and see our print room - it's great for making posters and zines.) reprographixed.com
