Anybody please help. The machine just automatically displays add toner message after turning on the machine. It don't initialize. All the motors are working fine, toner supply unit is okey. I replaced new development unit and IO board but still the same problem. I tried force toner supply and even initializing the developer but it don't work, the machine just says failed. The machine only has 80,000 copies and under warranty. Anybody has the same experience? Please I need your help badly. Thanks in advance.
