TR 8520 offline -- worked when set up, but not now


A Canon tech helped me set up my printer a couple of days ago, and I successfully printed a document from my computer.


Now when I go to print, I get the message that the printer is offline.  On the printer display the wireless connection shows it's active and when I pressed it, it has the correct WiFi network.


I also tested this by trying to scan, and the only option displayed was USB, not wireless.


How can I troubleshoot this?



This is whats (likely) happening.  The IP that your router assigned to the printer when it was installed has changed.  Now your computer thinks the printers IP is XXX, but its changed because the printer has gone to sleep, been shut off or not been used for some period of time.  Your router reclaims IP addresses it thinks are no longer needed or being used.  


How to resolve.  Assign the printer a static IP.  One that doen't change.  Now all devices on your network will always know how to to "find" the printer and also where to send print jobs because the destination will never change.  I'm willing to bet this will solve your "printer is offline" issue on your computer once it knows where to find te device.

Thanks, that makes a lot of sense.  Except how do I assign the printer a static IP?
