We just upgraded some of our Canon 5045s to 5560s and we seem to be having issues with them freezing on the pharos logon screen periodically. I have tried different power settings and it is happening on all the machines we received. After some testing we do feel like it is connected to heavy usage but we aren't certain of this. I am just wondering if anyone else uses these machines and if they are or are not having the same issue. I am just not sure if I should be troubleshooting with Canon or Pharos.
