I would have to assume you are using old firmware, which I would also guess to be 073.xxx.xxx.34540 specifically. Which is from 2015
If that is the case, simply update both to current and it will just start working with no loss of data, and if it doesn't, you can simply do a Wireshark, which is now conveniently built into the printer (the capture, you still need to use a viewer to read it)
The Trace feature in current firmware is at CWIS > Properties > Security > Logs > Network Troubleshooting It is not in releases before 2017
For reference, you can find a firmwares date from its version number
