if the shutdown process executed by the main board is overtime, the microcontroller directly cuts off the power supply of the printer.
The system in fig. 1 of the scheme can be used for realizing the power soft switching process for cutting off or opening the power. For example: when the printer is in a soft start state, the power key 2s is pressed for a long time when the system is in a shutdown/dormant state, the MCU outputs a control signal, controls the power control panel relay and switches on the 220V power supply of the printer. When the printer is in soft shutdown, the power key is pressed for 2s for a long time, and the system enters a shutdown process; the MCU informs the main board and executes the shutdown flow; after the main board finishes the shutdown process, the MCU controls the power control panel relay to cut off the 220V power supply of the printer; and when the shutdown process of the main board is overtime, the MCU directly cuts off the 220V power supply of the printer.
