I have a phaser 6280 hooked up over ethernet to a Macbook Pro and Mac Mini bothg running Yosemite (10.10.5). Suddenly I cannot find the printer over the network. Checked all connections and all working. Then I found that I could not print the Information Pages and that the printer just hung when I gave the command to print any of these. It did print the error history report but I couldn't see any issues there (although I'm not sure what I'm looking for). It sounds like it might be a hardware problem but I'm not sure. Has anyone come across this before?
