I have a Canon MF455dw, it's been in use for a little over a year. Recently, it would stop responding on the wired network and not able to print.
The printer is connected via Ethernet to the local network. When it is not able to print, the printer's physical Ethernet port is still connected and the LED lights show connected and blinking. However, pinging the printer from a PC shows no response.
Once I unplug the printer's network cable and re-insert it, it would start responding again and able to print. Another method is to power-cycle the printer. I've switched the network port and replaced the network switch to eliminate any network equipment issue and it still occurs. I suspect there is an issue with the printer's network interface. This occurs 2-3 times a day and very frustrating and time consuming having to troubleshoot it every time.
The printer is on the following firmware:
