Cannot detect printer via USB during firmware install

[Ethan 0]

I have a new espon xp 15000. I am trying to install the firmware but my computer cannot see the printer connect by USB, it only sees it through the network. I have tried the USB cable in all the available ports, printed a test page via USB once I disabled the wifi, restarted the PC and printer multiple times. Nothing seems to make it appear. Any ideas?

Please try this new file :

 

https://inkchip.net/download/INKCHIP.net_Firmware_UP_XP15000_v1.rar

 

 

1) Upload firmware which I sent. 

2) Switch on in normal mode(!!!) just turn on button . - dont put printer in Program Update mode.

 (No need to press few buttons while turn on the printer) 

The uploading process will stuck at 70-80% - it is ok! Open task manager and stop updater process. Printer will blink for about 5-15 minutes - then will power OFF. 

Now power on the printer - chipless firmware is installed in your printer!

 

After that try to activate again.
