* In order to prevent this error:
- Connect either USB cable or LAN cable. (USB cable is recommended, as it is not affected by other computers.) 
- Disconnect the telephone cable from your printer to prevent FAX interruption while firmware update.
- When connecting with a USB cable, do not connect the cable via a USB hub, as this may cause a connection error.
- When the printer is connected with a LAN cable, do not perform printing while the firmware is being updated.
- The printer may need service when a critical error occurs, such as the printer will not function after it has been turned on.
