• Code: 621
• Description: Finisher communication error
  While the IOB communicates with an optional unit, an SC code is displayed if one of following conditions occurs. • The IOB receives the break signal which is generated by the peripherals only just after the main switch is turned on. • When the IOB does not receive an OK signal from a peripheral 100ms after sending a command to it. The IOB resends the command. The IOB does not receive an OK signal after sending the command 3 times.
• Causes: • Cable problems • IOB problems • BICU problems • PSU problems in the machine • Main board problems in the peripherals
• Remedy: 1. Check if the cables of peripherals are correctly connected. 2. Replace the PSU if no power is supplied to peripherals. 3. Replace the IOB or main board of peripherals. 4. Replace the BICU.
