The cartridge is locked to one supplier
OEM cartridges carry an encrypted chip. The printer refuses anything else, and refilling or third-party supply is blocked at the firmware level. You are not buying a cartridge, you are buying a supply agreement you cannot leave.

Our cartridges are built as an open system: no chip lock-out and no authorisation handshake. You can run them alongside your existing supply, or as a second source, without replacing the printer.
