OH, you didn’t indicate you were printing successfully with the other cartridges you ordered, so I had to cover the bases. This is more common then one would think, I didn’t intend to insult your intelligence, I apologize if I did.
I will send you a new cartridge in the mail today, Please let me know your problem has been resolved after receiving it. You may have air worked into the lines and it may take some extra CC’s to get it all out.
Another suggestion would be to perform some cleaning on your Capping Station, Wiper Blade and Bottom of print head, this is always a good habit to get into at least 2x a year with the 3880.
