XP-15000 Read Failed -1 and Activation Key not recognized errors solved:
Situation:
Purchased the Activation Key and downloaded the Firmware Updater and Activation software along with INKCHIP.net_Firmware_XP15000_v2.rar file.
After installing the INKchip firmware in maintenance mode, started the Activation software. Some automatic popup appeared in foreign characters, by reflex clicked on a button (no clue, but probably a yes one 🤣). It did some background stuff.... once finished, then switched to English and tried to follow the instructions to no avail (error messages above).
Solution that worked for me:
1 - Unplugged the printer for a couple of minutes.
2 - Turned on in Normal Mode.
3 - Run the Installer again to Completion / Success.
4 - Run Activator again, this time there was no automatic popup, and was able to switch to English.
5 - Clicked Generate: "Serial & ID code" field gets populated.
6 - Clicked activate online (even if it was greyed out) and got a popup to insert the activation Key.
7 - Insert purchased Activation Key and OK
8 - "Activation Code" field gets populated
9 - Clicked Activate and got confirmation that product is now activated (dont remember if got one at step 7 😋)
10 - Copy Pasted all the info into a backup file in case needed later...
Hope this Helps Folks! :)
