The Epson PX-M780F is a highly efficient scanner, used widely in various professional settings. However, at times, users may come across an error code, specifically error code 0x21, displayed on the scanner. This error is indicative of an issue known as Scanner/ADF ALD PID excess speed error. There could be several reasons behind this error, such as ALD motor failure, motor driver failure, or cable/FFC disconnection.
When encountering error code 0x21 on the Epson PX-M780F scanner, it is crucial to troubleshoot the problem effectively. Firstly, check the ALD motor for any signs of failure, such as strange noises or physical damage. If the motor is damaged, it will need to be replaced by a professional technician.
