I recently upgraded to a Dell Optiplex 9020 running Win10 from a CompaqCQ60-615DX running Win 7. My problem is that I cannot seem to get my Canon PIXMA MG3520 printer (picked up second hand about 5 years ago, I believe it’s about 7years old), to work. Obviously, the biggest differences are a new computer and a new operating system. Since the printer still works and the Dell recognizes that something has been connected to the USB port, I think the problem is either something in Win10 or a driver issue. When I try to download and install the printer drivers, the printer cannot be detected for either USB or WiFi installation. (Since I have tried this installation more than once there may be residual files that may need to be cleaned up, but I do not know how to do this or where to look either). When I go into Control Panel it does not detect any printer. When I go to File/Print from Word and try to add a printer, my printer is there but indicates driver not available. The scanner is recognized and it states that it is functioning. Any thoughts?
