I don't know for sure whether this is a printer issue or a router issue. I've had the MX520 for about a year now. I only use it for it's Google cloud printing functionality. I rarely print, but whenever I need to it is never online. One trick that generally works is to unplug (reboot) my wireless router. But recently even that didn't work, so I went through the printer's menu to reset it up as a Google cloud printer. That brought it back online, but I found today that I still had to reboot my router to make it appear as being online and available.
Note: my printer is connected to the router wirelessly. If I check the printer it shows the router, but says something like, "unavailable." But as soon as the router is rebooted it connects.
Any ideas about what's going on?
