Solutions

Quick Diagnosis

SC672 appears right at startup. If the device noises start but it never reaches the home screen, the controller has halted execution.

Step-by-step Solution

  1. Shut down the machine and wait at least 30 seconds.
  2. Detach all extra non-essential hardware (finishers, extra trays).
  3. Reboot; if the device enters normal operation, reconnect peripherals one by one.
  4. If SC672 returns with no peripherals, it is a main controller board hardware fault.

Prevention and Maintenance
