I have tried multiple times to install firmware with same results.
 
	At 99% completion, I get the following pop-up message:
 
	The Printer's firmware was not updated.
 
	The firmware update did not complete. Try the following, then click [Retry].
 
	- Ensure that the printer is connected (USB/Wi-Fi/Ethernet) to the computer.
 
	- Ensure that the printer is powered on.
 
	Click [Retry] to perform the update again
 
	Click [next] to continue processing. 
	I am using Windows 10.
 
	I tried to install firmware by another PC ant it gives me the same error.
 
	I follewed carefully the instrucions even by youtube.
 
	I can see the printer so it is clearly plugged in and turned on.
 
	It is connected USB to the computer.
