These cartridges work well and the color printing helps in the documents I use. They are expensive but I have not found any other quality replacements. However I am printing less paper these days!
I installed it and I figured my copier was broke. Then I realized the ink cartridge I believe not positive is dried up. It did not have the yellow tape and it did not have it wrapped up in the cellophane envelope. I will be returning it. I hope everything is OK.
