Hi All!

I had some error reading failed 1 for XP15000!
So firstly i deleted all old files, and the download again this firware!
https://inkchip.net/download/INKCHIP.net_Firmware_99_XP15000_v1.rar
After firmware load on 70% i took plug from the wall away, and disconnected printer from the electricity power.
Then turn on again in normal mode 😃 and it works now!
Thanks a lot for your support!
