Does eco-tank ink dry out if I don't print often?

Yes, like all inkjet ink, eco-tank ink can dry in the print heads if unused for extended periods (3-4+ weeks). Most models run automatic maintenance cycles to prevent this, but printing at least once a week is recommended to keep the heads clear. This is the biggest downside for light-use households.

Can I use third-party ink in eco-tank printers?

Technically yes, but it's generally not recommended — third-party ink can void your warranty, clog print heads, and produce inferior color accuracy. Unlike cartridge printers where third-party ink saves significant money, eco-tank printers already have extremely low ink costs, making the savings from third-party ink negligible.
