To keep this plotter performing at its best, it’s worth choosing proven ink for HP DesignJet 30 and the right printhead for HP DesignJet 30—matched to the device and your workflow. Ink cartridge and printhead: what matters in everyday use In this category we focus on Ink Cartridges and Printheads for the HP DesignJet 30. This model works with separate ink supplies and dedicated heads, which means you can restore print quality very effectively by replacing exactly the component that is worn out. The right ink for HP DesignJet 30 supports: - smooth gradients and accurate color reproduction for photos and presentations,
- sharp lines for technical drawings and CAD-style output,
- stable, repeatable results over longer print runs,
- clean work thanks to well-sealed cartridges and correctly matched consumables.
If you notice fading, missing lines, or color shifts, the cause is often a worn or clogged head rather than the cartridge itself. That’s why having the correct printhead for HP 30 on hand can save time and reduce waste.

How to choose the right ink for HP 30 (and avoid common issues) When selecting ink for HP DesignJet 30, always verify the code and color. Many customers search by shorthand phrases like “30” or by printer code C7790D—both are correct starting points, but the consumable model (HP 84 / HP 85) is what guarantees a perfect match. Typical user issues we help solve for this model include: - Streaking or missing lines – often solved by replacing the relevant HP 85 printhead (not necessarily the cartridge),
- Color inconsistency – may occur when one light color head (Light Cyan/Light Magenta) is worn,
- Clogging after long downtime – if the printer sits unused, heads can dry; replacing the head restores flow faster than repeated cleaning cycles,
- Weak black – check whether the issue is the HP 84 black ink cartridge or the black head condition and maintenance routine.
