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.

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.

Is there a way in TelNet to verify if a key was activated and when. I sell approx 20-30 key per week and my clients ask for an answer in the key -10092
