The cartridges always fit and never have a problem with them....And you send envelopes to send the used ones back in.....I never have a problem with your cartirdges that I buy from you.
The cartridges leaked on my hand when I pulled off the tab. Both blue and yellow. Blue was the worst. After I installed the ink, the message was they weren’t the right ones. I cleaned the ports with alcohol and after three tries, the printer accepted them.
