5.6.3 Firmware update
Click “Firmware update” link and update the interface firmware through this web page (if you have set
the safety password, you can enter only when you have entered correct password, see Figure 5.6.5),
see Figure 5.6.3. Click “Browse” button to select the firmware needing to be updated, then click
“Update” button to update the firmware. When the web page like Figure 5.6.4 appears, it indicates that
the updating is successful, and the printer will restart automatically. When the file is wrong or the
updating fails, the web page will pop up the prompt message of invalid file format or updating failure.
