Self-Diagnostic Mode

Self-Diagnostic Mode at Power On

As soon as the main machine is powered on, the controller waits for the initial settings of the copy engine to take effect
and then starts an independent self-diagnostic test program.
The self-diagnostic test checks the CPU, memory, HDD, and so on. An SC code is displayed if the self-diagnostic
program detects any malfunction or abnormal condition. In the case of the error that can start the machine, record it in
System Error Log.
