How to choose: ink cartridge vs. printhead, and what users of HP DesignJet 90 often struggle with When buying ink for HP DesignJet 90, first confirm what needs replacing: the ink cartridge supplies ink, while the printhead is responsible for placing ink precisely on the paper. If you notice quality issues even after replacing the ink, the printhead may be the cause. Common issues reported by HP DesignJet 90 users include: - banding or stripes across images (often linked to a worn or clogged printhead),
- missing colors or faded areas (a specific color printhead may need replacement),
- frequent cleaning cycles and faster ink usage (can happen when the printer tries to compensate for weak nozzles),
- color inconsistency between print runs (a sign to check the condition of the relevant printhead).
