What you get with HP 72 inks in the DesignJet T620
The HP DesignJet T620 works with the HP 72 ink system, valued for smooth tonal transitions, crisp edges and consistent results across long print runs. With the right ink for HP T620, you can expect:
clean, readable thin lines—important for CAD and architectural plans,
predictable color reproduction for presentations and posters,
good coverage and controlled ink laydown, reducing the risk of smudging,
stable performance when printing large formats and longer jobs.
Equally important are the printheads. A fresh, properly matched printhead helps maintain nozzle health and prevents quality drops such as streaks, missing lines or color shifts. That’s why, alongside cartridges, we also offer dedicated printheads for HP DesignJet T620.

How to choose the right ink for HP DesignJet T620 (and when to replace a printhead)
When selecting ink for HP DesignJet T620, start with two practical questions: how much you print and what you print most often. For frequent CAD/line work, Matte Black is typically consumed fastest; for posters and presentation graphics, the color set and Photo Black may run out sooner. XL cartridges are a smart choice when you want fewer replacements and steadier workflow.
Print quality problems are often linked to maintenance rather than the cartridge itself. Common issues reported by users of the HP T620 series include:
faint lines or missing segments in drawings,
banding (horizontal streaks) on solid fills,
color inconsistency after long idle periods,
messages suggesting printhead maintenance or replacement.
If cleaning cycles don’t help and defects repeat in the same areas, it may be time to replace the printhead for HP T620. A new, correct OEM printhead often restores the sharpness and uniformity that large-format work demands.
Original vs compatible: what to know before you buy
In this specific subcategory we focus on Original OEM solutions: OEM cartridges and OEM printheads designed for the HP 72 system used by the HP Designjet T620 Series. Many customers choose OEM for maximum predictability and manufacturer-grade consistency, especially when prints are client-facing or need to meet internal standards.
If you are considering a compatible option in general, it’s worth knowing that our compatible cartridges from DrTusz.pl are designed to be just as reliable in everyday use as originals, while offering excellent value. The key is always correct model matching (HP 72 / T620 compatibility) and choosing a trusted source—this is exactly what we focus on in our store.
