WF-6090 New maintenance box error, not recognized

[WF-6090 New maintenance box error, not recognized]

The printer remained working properly until the maintenance box was finished.
I bought a new maintenance box but now it is not recognized and I do not know how to solve the problem, my purchase order is (# 20464846) and my license is 3E1A33FF97C1EXXX.
I would like to know how to use my new maintenance box.

The keys were used successfully.
Just change the printer cards and they worked.

[2 WORKFORCE WF-7720 NAO ATUALIZAN -- changed printer cards]

I ended up changing the 2 cards, I never managed to activate them.
The new ones activated instantly.
If you need any reference about the cards you remove and could not be activated to improve the service. I am glad to support.
