My Canon multifunction printer is not working properly. I have a desktop computer which is running on Windows Xp operating system. The computer is connected to the Canon multifunction printer. The problem is while I am on call, the Canon MX860 suddenly starts scanning of some documents and because of it the call in progress gets disconnected. During this time if the printer is tried to switched off, it does not work. Therefore if anybody else is facing similar Problems with Canon MX860 Multifunction Fax then please share some information about the same. Thanks in advance.
