Blue Screen-Multiple Errors for HP Envy 7640

[HelpPlease33]

For the last month or so I am getting blue screen errors with lights flashing and varying codes like: B84952B0 and C4EB1600.  It will also tell me that there is something wrong with the printer and to turn it on and off again and again.  How do I fix this?

I see that you are facing printer issue.

Kindly refer to the steps below and let me know if that fixes the issue.

Please perform the below steps and let me know

1) Turn off the Router, Printer, and the computer/ mobile devices. 

2) Wait for 60 seconds. 

3) Turn on the Router first and wait for all the lights to stabilize. 

4) Take out the cartridges. 

5) Unplug the power cord from the printer & wall. 

6) Wait for 30 seconds. 

7) Plug the power cord back into the printer and wall, ensure the printer is plugged into the wall & not to a surge protector. 

😎 Insert the cartridges back into the printer.

None of these steps worked.  I uninstalled the app and now I can't reinstall it.  The Printer refuses to find a network.  When I have it hardwired to the computer trying to download and install firmware drivers it fails to see the printer.  The printer either holds a blue screen or when it does not it says Printer Error with all lights flashing and says There is a problem with the printer.  Turn the printer Off, then On.  When I do this the process starts all over again.  On occasion I'll get the home screen for a matter of seconds and that is when I have tried to re-establish the network connection and it fails.  So now, I no longer have the app on my desktop because I uninstalled it per your advice and can't reinstall it without some type of connection to the printer which I cannot achieve.  However, I was just able to print a report with regard to the connection issue and it states that the wireless radio is not functioning.  Contact HP Support.  What do I do with this?  As soon as I got that far it went back to Printer Error, flashing lights, "There is a problem with the printer.  Turn the printer Off, then On." again.  Please advise.
