Firmware errors at 99%

[Kathryn 0]

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.

There are no error codes.

I am using Windows 7.

 

I can see the printer so it is clearly plugged in and turned on.

It is connected USB to the computer.

You should convince that you install the chipless firmware in NORMAL mode instead of UPDATE mode.

Please read the instruction from our website carefully:
