My cannon MG7520 printer will turn on and start to go through its normal routine, but then unexpectedly turns off. The power cord has been checked, unplugged and replugged. Same result. Looking for other solutions if there are any.

Strangely enough this same thing just started happening for me today as well. With my MG7520 printer. Haven't used it in a few days. But today when turning it on, it goes through a cycle of internal printer head movement or whatever for ~20 seconds, then just turns off. Tried removing print cartridges as well, same issue. No error messages on the screen before it turns itself off.
MG7520 printer. The printer starts and turns off after 15-20 seconds. IF I can get it to turn back on, I receive “The printer was not turned off correctly…” message. Usually it starts through a cleaning process and shuts off. I have discovered today, that if it turn off my router, the printer acts normal. As soon as I turn on the router, 10-15 seconds later, the lcd screen freezes and the printer turns off. I have tried resetting the wireless settings with the same outcome. This started happening within the last week or two. I’ve never had this issue in the past.
I was searching this morning for the “power was not turned off” message and came across this post regarding turning off your router/access point:
My MG7520 seems to function normally until I power up the router—frozen screen, shuts down. If I leave the router on and power up the printer, I may get to the message again or it just shuts down while cleaning.
