How to choose the right cartridge or printhead (and avoid common issues) If you’re unsure what to buy, we encourage you to start with your printer symptoms and your printing habits: - Faded colours or sudden colour shifts – often indicate an ageing printhead or an uneven ink supply; consider replacing the relevant HP 85 printhead.
- Missing lines / banding – can be caused by clogged nozzles or a worn printhead; a new printhead is frequently the most effective fix.
- Printer sits unused for long periods – dried nozzles are a common problem in the 90 Series; using fresh, quality ink for HP DesignJet 90r and keeping the system maintained reduces downtime.
