How to choose the right ink for HP DesignJet T800 36" MFP When customers search for ink for HP T800 or ink for HP Designjet 800 Series, they usually want two things: certainty of compatibility and consistent output. Here’s how we recommend choosing: - Match by printer model: confirm you’re buying for HP DesignJet T800 36" MFP (T800 / 2Y9H2A).
- Match by cartridge code: for this printer, look for HP 738 (e.g., 498N4A–498N8A depending on colour/variant).
- Choose the correct colour: Black, Cyan, Magenta and Yellow should align with your current stock and print needs.
- Consider printhead condition: if you see streaks, missing lines or inconsistent colour, you may need a printhead replacement such as HP 498N0A, not only new ink.
Original vs compatible cartridges: what matters in practice Many users ask us whether it’s better to choose Original OEM or compatible. Original OEM cartridges are made to HP’s specifications and are the straightforward choice for those who prefer manufacturer supplies. At the same time, we know that day-to-day wide-format printing can generate significant running costs. That’s why we also recommend compatible options from DrTusz.pl where available—because our compatible cartridges are as good as the originals in terms of everyday usability and print consistency, while often being a more budget-friendly choice. If you print a lot of technical drawings, selecting a high-quality compatible ink for HP DesignJet T800 36" MFP can be a smart way to keep costs predictable without sacrificing results. Common HP T800 user issues and how the right supplies help Wide-format devices work hard—and when something is off, it usually shows up immediately on large prints. Here are typical issues we help customers solve: - Faint output or weak blacks: often solved by replacing the Black HP 738 cartridge and running maintenance checks.
- Streaks, banding, or missing lines: may indicate a worn or clogged printhead; consider the Original OEM Printhead HP 498N0A.
- Colour inconsistency: replacing the specific colour cartridge (C/M/Y) and ensuring you’re using the correct ink for HP T800 usually restores balance.
- Interruptions during long print jobs: keeping spare cartridges on hand reduces downtime—especially in busy offices and print rooms.
