Hi Dengarhunted,
The imageCLASS MF216n is very much compatible with Windows 10. With this said, in order for us to better assist you, we will need some additional information. Do you mind answering a few questions so we can get a better picture of your situation?
1. How is the imageCLASS MF216n currently being connected to your system? Is it connected via USB or via an eithernet cable?
2. If you power cycle the router does the issue continue? "Unplug the power cord to your router and wait a few minutes and plug it back in". Are you able to print at this point?
3. Are you receiving a specfic error when you attempt to print?
4. Is the unit's power cord being plugged into a power strip or is the cable plugged directly into the wall outlet? For trouble shooting purposes try plugging the power cord directly into the wall then test the unit.
