If the printer prompts that the printer hardware is faulty, the first step is to restart the device. Sometimes, minor glitches or temporary system errors can be resolved with a simple reboot. After restarting, check if the fault prompt still appears.
If the issue persists and the printer cannot return to normal working condition, it can be due to an internal hardware malfunction. In this case, it is recommended to contact the after-sales service for professional diagnosis and support.
Note:
Do not disassemble or attempt to repair the printer yourself, as this can cause further damage. At the same time, it will also cause the warranty to become invalid.
