SOLUTION: After a 1:57 hold time with Canon customer service.... I have the solution! (and that was 2 hours, not 2 minutes) If this is happening to you it is very easily fixed. [Removed per forum guidelines] Although I wish I could make up for my 2 + hours of time. The tech told me that when they walked into the office Tuesday morning, "the stuff had hit the fan" because this has affected many models and they don't know what caused it. Here is what you need to do to fix it:
Completely unplug your router and then turn on your printer (it won't stay on if your router is because of a linking problem with the router, that we are going to fix.) So this is the step-by-step for the MG6620 and probably those models with similar menus, but whatever model you have just try to get to your DNS Server Setup. That is where the setting is that needs manually changed. So for the MG6620:
On the menu swipe to Setup, then find Web Service Setup then DNS Server Setup. Select Manual. Press each set of numbers and change them all to 000 except the last set. That needs to be 001. So your DNS will look like this: 000.000.000.001 Click OK, then click No.
That's it. You should be good to print.
You are welcome! Too bad someone at Canon doesn't just post this somewhere. Would've save a lot of people a lot of headaches, I'm sure.
Ha. I didn't want to turn off my house wifi so I 'took my printer for a little ride' down to the school parking lot (I have an ac outlet in my car). Turned it on, changed the DNS setting, drove home and viola it prints!
1. I did a factory reset so seems to me it would know nothing of my router and therefore i'm confused as to why the DNS settings would come into play at all. any insight?
2. Should i still do the firmware update that Canon provided yesterday via PrinterUpdate.exe on the usb cable. I'm tempted to leave well enough alone at this point.
