WF-2750, changed circuit board after buying chipless firmware

Recommended Posts

I blew something when cleaning the print head, and I got error 0x9. I bought another printer for 30 that was messed up and put the head & board in mine, it its working but won't accept my activation key. Its all on the same printer though, I just have to flash the new circuit board because my other one kept saying paper jam. I'm going crazy because I spent 30 on both printers, and 35 for chipless firmware. So 95 thus far, and I don't think I need to buy another key since this is going in the same printer & my thing doesn't expire till mid February.

 

Please help

If You have NOT used Your Key yet - then you dont need to buy another chipless key

 

But if it was used - You cant use it second time on other printer.
