I've had this printer for almost 2 years. When it was only a month old, I got the 255 error and Canon told me to fix the ipv4 address. That worked.
Got error again several months ago. Canon told me to power off, unplug, let it sit 20 minutes, then reconnect and restart my laptop. This allowed a power build up to drain off. It worked.
A month or two back, 255 became a daily issue. Now it doesn't always clear up with the process. I've reinstalled drivers, let printer sit for a day or two. Results unpredictable.
Canaon now says only support is through this forum.
Any suggestions? Or do I have a 40 pound white boat anchor?
I'm offended by your response. "If you do, in fact, have . . ."
You must think I'd make upa string of numbers and letters and a problem just so I could post to some obscure website.
Well, I do NOT, in fact, have the printer any longer. Due to your response and Canon's lack of support, I disposed of the boat anchor.
We sincerely apologize for the difficulties and inconvenience you have experienced.
The MF726Cdw is still supported by our Enterprise & Desktop Solutions Divisions telephone support group, so I would like to apologize for this misinformation.
I would also like to apologize for the poor choice of wording in the "If you do, in fact, have" message, as that is not at all what we meant.

We are dedicated to doing our best to provide excellent support of our products, warranties, and customers. If, in the future, you reconsider your decision, we hope you will provide us with another opportunity to serve you.
