Perhaps You have entered the incorrect IP address.
You entered 192.168.20.10
I believe it should be something like 192.168.0.10
Check the subsequent IP addresses one by one, starting with 192.168.0.1, and so on.
See if your printer comes up within the first 10 ending numbers.
The address 192.168.20.10 is the primary DNS in printer.
As said, I tried every address from 192.168.0.1 to 0.10…
Besides, when loading paper from the roll feeder, front panel
still asks to choose "roll" or "sheet", then the type of paper anyway…
So I don't understand your option front panel OR rear feed…
Then back to the bloody routine : "Feed roll from rear panel" then "Paper edge too far from blue line" etc.
Please be aware I loaded rolls and rolls without any problem before, just inserting the paper edge and that's it. I just stopped using printer for 3 weeks, and now these problems… Fed up…
Will uninstall with uninstaller and reinstall from scratch, we'll see.
