A chip re-setter is basically a tool that sets the chip on the cartridge and fools the printer in thinking that the refilled cartridge is a new one compatible to the machine. Some times they work and some times they may not.
For some unknown reason, re-setters do not seem to be as available as they once were. A year or so ago, I bought a few from Currys who were having a clear-out of these devices, selling them a very low prices.
Have you had a look at same type compatibles for the printer or even a CISS unit (if available), possibly via a search on eBay. A CISS unit will save quite a lot of money, and give a far better time saving result.
