5.14.1 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 follows the path of the flow chart shown below and checks the CPU, memory,
HDD, and so on. An SC code is displayed in the touch panel if the self-diagnostic program
detects any malfunction or abnormal condition.
