Wmaster1o 6 Report post Posted June 17, 2021 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. Share this post Link to post Share on other sites
