My mom uses a Canon ImageCLASS D570 printer and scanner. Her scanner stopped working so she asked me to fix it. I can't seem to figure out to fix it. The printer is connected to the computer by WIFI. My mom said last time it happened she unplugged her mac the printer and the extension cable they were on. I decided to do it just to try it. I think the problem isn't from that though. Any ideas on what I should do?
