Haven't used it yet! Currently my spare for original cartriges which are about to fail. Terribly expensive and I'm not fond of the 8025 printer and lack of human service available.
I had to return them as I had to return the 8035e printer I just bought as it was a terrible experience trying to get it to work properly. I did purchase a much better quality printer the 9025e and bought the 962 cartridges for it.
