https://community.usa.canon.com/t5/Office-Printers/MF-Toolbox-scan-not-working-after-installing-a-second-canon/m-p/255926#M7835 <P>I have a canon mf4770 installed via usb, and all worked well. Installed a second canon mf8080 via usb as well and can no longer use the scanner function, as it no longer sees the usb connection. Uninstalled all drivers for both and reinstalled the 4770 and worked again by itself, but not after loading the 8080 again. Is there a fix for this or is it just not possible to mix canon printers on one machine.</P> Fri, 28 Sep 2018 17:04:47 GMT SK99 2018-09-28T17:04:47Z https://community.usa.canon.com/t5/Office-Printers/MF-Toolbox-scan-not-working-after-installing-a-second-canon/m-p/255926#M7835 <P>I have a canon mf4770 installed via usb, and all worked well.
