How to pick the right cartridge (and avoid common issues) If you want to choose the best ink cartridge for HP 3420, start with two questions: do you print mostly text or also colour, and how often do you print? For frequent printing, a compatible multipack or a 2-pack of black cartridges can be the most cost-effective. For occasional printing, consider keeping a spare cartridge sealed to avoid last-minute surprises. Users of the HP Deskjet 3400 Series sometimes report issues like faded prints, streaks, or the printer not recognising a cartridge. In many cases, the solution is simple: - Streaks or faded text – run the printer cleaning/alignment utility and make sure the cartridge is seated correctly.
- Cartridge not detected – remove and reinstall the cartridge; gently clean the electrical contacts if needed.
- Colour looks “off” – run alignment, print a test page, and ensure you’re using the correct colour cartridge (HP 28 / C8728AE).
- Ink dries out – if you print rarely, print a small test page every 1–2 weeks to keep nozzles fresh.
