- Tens of millions of printers are sold each year, including copiers and multifunction devices. Each printer needs an ink or toner cartridge, depending on the type of printer. This is where the problems arise that anyone who owns such a device has encountered – the price and availability of cartridges. A set of original cartridges for the printer we bought can sometimes cost more than the printer itself. On the other hand, it is not always possible to buy cheaper replacement consumables. This is often due to the fact that the manufacturer of the printer has implemented a Digital Rights Management (DRM) protection in the chip connected to the cartridge. Bypassing such protection is not trivial, and when a way to do so is learned, it is not disclosed because of the commercial value of such knowledge. The goal of this paper is to determine if it is possible to find out for ourselves how selected DRM protections work by using reverse engineering, and to develop a way to reset these protections so that we are not tied to the price and availability of consumables on the market, as we can remanufacture our cartridges ourselves, which is especially important in the context of the Right to Repair.
