A critical error may occur if another computer or application communicates  with the printer (for example, printing) while the firmware is being updated.
Do not turn OFF the printer or disconnect the interface cable (USB or LAN cable) while the firmware is being updated. 

* 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.
