i-sense MF635Cx\nWindows 10 64-bit\nUsing WiFi to connect to the printer.\n\nI have successfully printed and scanned in the past week.\nBut every time I reboot the computer, or hibernate, or the printer switches off and I have to switch it on again, or whatever, it is "gone". Can't print, can't scan, can't get toner status. \n\nI could be related to the IP changing. \n\nI have succeeded in getting it working by rebooting the PC. But that doesn't always. work. Sometimes I have to uninstall the printer and re-install it again before I can print. Every 2 days!!!!! Nobody can live like that.
