How to choose the right ink cartridge for HP Designjet T770 Series We encourage you to choose ink for HP T770 based on what you print and how you print. A few proven rules make ordering easier: - Pick XL if you print regularly (batch CAD sets, office production, frequent deadlines). You’ll reduce interruptions and often optimize cost per ml.
- Choose the right black: Matte Black for plain/matte media and crisp technical output; Photo Black for coated media where deep black density is crucial.
- Watch Gray levels if you print monochrome drawings or presentations—Gray helps maintain neutral tones and smoother gradients.
- Replace printheads when symptoms persist: if banding, missing nozzles, or color inconsistency continues after standard maintenance, the HP 72 printhead may be the real cause.

- Color shifts between prints – can happen when one color is running low or a head is near end-of-life.
- Frequent cleaning cycles – sometimes caused by long idle periods; keeping fresh, correctly stored cartridges helps keep the system stable.
- Choosing the wrong black for the media – results may look “washed out” or not dense enough.
