Since the other cartridges are recognized and only the magenta is causing the ink-system error, I'd suspect the magenta cartridge or its contacts. Try removing it and gently cleaning the cartridge contacts and the contacts inside the printer, then reinstall it firmly. If possible, test with another magenta cartridge. If the error follows the cartridge, the replacement cartridge/chip is likely the problem.
