Finally resolved!1. Uninstall the drivers and MF Toolbox2. Download and install drivers and Toolbox from here: http://www.usa.canon.com/cusa/support/consumer/printers_multifunction/imageclass_series/imageclass_mf4890dw#DriversAndSoftware
Thanks fnkhan!I'm expecting Canon to issue an update that does this gracegully.Win10 is becoming popuylar quickly (free upgrade) and my printer is relatively new - so they should address this ASAP. Again, Canon - looking for a solution please.
