A:AnswerProbably less than 45 days. I bought a 67 cartridge and put it back in case I ran out of ink and it dried up. I took it back to Best Buy and they refused to exchange it saying it was over 30 days old. Lesson learned. DO NOT buy ink cartridges from Best Buy unless you are going to use them immediately.
A:AnswerVery simple. Put your finger on the top of the cartridge you are taking out. Pay attention to the direction of the outgong carridge. Push forward and up and iot will snap into place.
A:AnswerHi Cassy, thank you for asking. Yes, 67 (or 67XL - high yield) is the correct ink cartridge for the Envy 6400 series printers. These printers are also Instant Ink capable, for worry-free, timely and cost-saving replacement with HP Instant Ink.
A:AnswerHP often sells the same model printer in different parts of the world. Typically, printers in different regions are set to use different cartridges to help control the flow of printers and ink from places where they're less expensive to places where they are more expensive.
