Hello Imaxpr!
Thanks for responding to our message!
The PIXMA MX310 is not compatible with Windows 10. We suggest downloading the Windows 7 or Windows 8 drivers to see if that allows you to scan. For the Drivers please go here: http://Canon.us/vxyv If not please contact our Technical Support Team by phone or email here: http://Canon.us/ContactCF
We hope this helps!
