How to choose the right ink for HP T770 – practical tips before you buy When selecting ink for printer HP DesignJet T770 - CN375A, we recommend checking three things: - Printer designation: match the cartridge system to HP DesignJet T770 Series / CN375A / T770.
- Color and purpose: Matte Black is typically used for strong linework on matte media, while Photo Black supports deeper tones on glossy/photo media.
- Capacity choice: if you print frequently, an HP 72 XL ink cartridge can be more convenient by reducing replacements and interruptions.
Also remember that on large-format printers, ink issues can be confused with printhead wear. If you notice streaks, missing lines, or inconsistent colors, the cause may be: - a clogged or worn HP 72 printhead,
- air in the ink system after long downtime,
- an almost-empty cartridge in a frequently used color,
- media/profile mismatch (especially for presentations and posters).
