Turning off the power switch cuts off the drive voltage supply, launching a firmware power-off sequence as shown below.
If the power cord is disconnected from the wall outlet or the top cover or any other cover is opened, the printer cancels the ongoing operation and shuts down
immediately. Since printhead capping may or may not have been carried out properly, reconnect the power cord to the wall out and turn on the power switch.
Making sure that the printer has entered online or offline mode, turn off the power switch.
