• Code: SC670
• Description: Engine Startup Error
  At power on or after the machine leaves the energy conservation mode:
  • ENGRDY signal does not assert
  • IPURDY signal does not assert After power on and the prescribed time has elapsed:
  • No EC response from the engine
  • No PC response from the engine
  • No SC response from the engine During machine operation mode:
  • Write to Rapi drive failure (could not locate destination on the PCI)
  • After the /ENGRDY signal asserts with no effect.
• Causes: • BCU ÅÆ Controller Board disconnected
  • BCU board defective
  • Controller board defective

• Causes: • Feed-in motor connector, harness loose, broken, defective
  • Paper length sensor connector, harness loose, broken, defective
  • Feed-in motor defective
  • Paper length sensor or encoder is defective
  • ADF main control board defective
