Pixma MG7520 will not power on/off correctly

[Anonymous]

I have a PIXMA MG7520 that refuses to complete the power ON or OFF processes correctly.

1)  When I turn on the printer I am get this really annoying message.

 Which is immediately followed by 

This messages stays on the screen for 45-70 minutes.

Pressing the power or home buttons do nothing, nor does sending a print job to the printer.

2)  When I go to turn off the printer I push the power button specifically to avoid problem #1 above.

The screen displays

That messages stays on the screen for days on end.  So far "a while" once lasted for 39 days before the power blinked landing me back at problem #1.

I now get to where I turn on the printer the day before I want to use it.

How do I correct these problems?

Yes, I checked for latest firmware.

Greetings,

Based on your description...  Cannot power the device on or off successfully, I believe the printer requires service.

Steps I would perform:

The printer needs to connect to stable, reliable power.

Unplug the device

Press and hold the power buttin for 15 sec.

Wait about 60 secs and reconnect to the printer to power.

Attempt to power on normally

If it doesn't, the printer will require service:
