C05: ORANGE, ORANGE, ORANGE, GREEN, ORANGE, [pause] = Franking machine is not communicating with the communication device

  1. Wait 60 seconds. The error may clear on its own.
  2. If the error does not clear:
    1. Unplug the device from power.
    2. Wait 10 seconds.
    3. Reconnect to power. This will update the firmware and reboot the communication device.
  3. Replace the USB cable. Make sure that the new USB cable is no longer than 2.43 metres.
     

C06: ORANGE, ORANGE, GREEN, [pause] = Wireless network configuration may be incorrect

  1. Disconnect the USB cable from the franking machine.
  2. Run the Network Setup Software to confirm the correct wireless network was selected and that the wireless key was entered correctly.
  3. If the settings fail to update, reset the device to the factory defaults.
  4. After making changes, power cycle the device by disconnecting the power, waiting 10 seconds, and reconnecting the power.
     

C07: ORANGE, ORANGE, GREEN, ORANGE, [pause] = There is problem transferring data to the franking machine

  1. Wait 60 seconds. If the error does not clear, disconnect the power, wait 10 seconds, and reconnect the power.
  2. Replace the USB cable. Make sure that the new USB cable is no longer than 2.43 metres.

C08: ORANGE, ORANGE, ORANGE, GREEN, [pause] = Communication Device does not detect a network connection

  1. Check that the network cable is connected properly.
  2. Check that the network port to which the cable is connected is active.
  3. If adjustments are made, disconnect the USB cable and power cycle the communication device by disconnecting the power, waiting 10 seconds, and reconnecting the power.

C09: ORANGE, GREEN, ORANGE, [pause] = Network gateway address is not entered

  1. Enable DHCP on your network.
  2. Disconnect the USB cable from the franking machine.
  3. Download and run the Network Setup Software to verify and manually configure the network gateway.
  4. In addition to the DNS, you will need to specify the IP Address and Subnet mask.

C10:  ORANGE, GREEN, ORANGE, ORANGE, [pause] = Network is transmitting data not compatible with the communication device networking protocol

Resolution:

  1. Wait 60 seconds. If the error does not clear, disconnect the power, wait 10 seconds, and reconnect the power.
  2. Check the network cable and the network port.
  3. If using a wireless network, make sure the wireless access point is close enough to the communication device to ensure stable reception.

C11: ORANGE, ORANGE, [pause] = MAC address access error

  1. Reboot the communication device:
    1. Unplug the device from power.
    2. Wait 10 seconds.
