  1. 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
  2. Hi I have WF-3720 with custom firmware (from your site) but not activated yet. The printer has no genuine cartridges, just refillable chipless. Do I need genuine cartridges installed to use activation code? Thank you.
