Epson WorkForce 3720: Wrong ID code

[kot_shenshirsk 0]

Hi

 

I've purchased the code and trying to activate. Order #16731

Flashed firmware as per docs. However  when I try to activate I'm getting Wrong ID code. And activation program doesn't recognise the code.

Printer model: 3720
Firmware version: CL03K7

Hi! Please try this new file for you.

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!
