Hi! Thank you for your help I did what you told me I am just hoping it will work. Right now it is telling me updating firmware and it is blinking like you said and it's telling me not to shut it down that when update is done it will shut down on its own. I don't think it worked
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!
