MG7520 with latest firmware (4.0.0) prints one or two pages after restart and then looses wifi connectivity to both iMac desktop and Macbook Air (both running latest OSX and drivers). The print queue says "Looking for Printer" and then "The printer is not connected". Otherwise wifi is working correctly for all other devices.
Power off / power on cycle on the printer usually fixes the problem, but only for one or two printed pages. Logging into the wifi network from the printer also temporarily fixes the problem, but neither of these is a permanent fix.
Another symptom is what seems like extremely long clean cycles (~2 minutes?) before printing after the printer is powered off.
Any ideas? Does this sound like some sort of electrical / hardware failure on the printer itself?
Thanks
