The Seiko SPT510 Damper is a high-quality solvent and UV-resistant ink damper for grand-format printers using the Seiko SPT510 printhead — including Infiniti Challenger, Icontek, Speedvision SpeedJet, EFI VUTEk QS, Roland AJ, Taimes, Ataline, and CrystalJet platforms. Corresponding to VUTEk part number 45094578, this damper includes a precision O-ring on the outlet side for a proper seal between the damper and the SPT510 printhead interface. It is compatible with both solvent/oil inks and UV-curable inks — matching the SPT510's dual-chemistry capability. This damper is rarely available as a standalone part; most suppliers only provide it bundled with a new SPT510 printhead — we stock it separately for service replacement without requiring a full head change. Rarely available as a standalone part — replace at every SPT510 head installation. The Seiko SPT510 damper is typically only supplied as part of a complete printhead kit. Digiprint USA stocks it separately, allowing you to replace the damper without purchasing a new head — and ensuring you always replace the damper at every head installation rather than reusing the worn original. Worn dampers on the high-flow SPT510 platform cause ink starvation that produces banding and nozzle loss even with a new head installed.

About the Seiko SPT510 Platform and Ink Delivery The Seiko SPT510 is a grand-format industrial piezo printhead with 510 nozzles, steel-plate nozzle protection, and a 6–8kHz firing frequency designed for high-volume outdoor signage and banner production on 3.2m+ wide grand-format printers. Unlike smaller-format printheads, the SPT510 uses a pressurised external ink supply system that delivers high ink flow volumes to sustain production print speeds. The damper sits in this supply path, filtering ink particles and stabilising pressure before ink enters the SPT510's internal delivery system. The SPT510's dual chemistry rating (solvent/oil and UV) means this damper must resist both traditional eco-solvent carriers and the photoinitiators and monomers in UV-curable formulations — explaining the "solvent and UV resistant" specification that distinguishes it from standard eco-solvent-only dampers. Signs Your SPT510 Damper Needs Replacing • Banding or nozzle row loss at high print speeds — ink starvation on the high-demand SPT510 supply path • Air bubbles in the ink supply line between the tank and head • Ink leaking at the damper-printhead connection — O-ring seal failure • Nozzle drop-out returning immediately after head cleaning — continuous air ingestion through a failed damper • Ink starvation patterns at maximum print speed despite full ink supply tanks SPT510 Service Checklist • Ink damper (this listing) — replace at every SPT510 head installation • SPT510 printhead — IRH1513D-3322 / IRH1513D-3311 (replaces IRH1513D-1321) — also stocked • Head data cables — 30-pin parallel interface cables per SPT510 head • Ink filter — inline filter upstream of the damper in the supply path Why Buy from Digiprint USA • Standalone availability — no need to purchase a full new SPT510 head just to get a replacement damper • Solvent and UV resistant — works with both ink systems the SPT510 supports • In stock in Doral, Miami FL — same day shipping before 2PM EST • We also stock the SPT510 printhead (IRH1513D-3322) for complete head + damper service kits • Ideal for Latin American VUTEk, Infiniti, Icontek, and Speedvision grand-format operations using Miami freight forwarders View our full range of ink dampers for wide-format printers stocked by Digiprint USA. Frequently Asked Questions Why is the SPT510 damper usually only sold with a new printhead?Seiko and most of the Chinese-branded grand-format printer manufacturers supply the SPT510 damper as part of the complete printhead kit — the damper is considered part of the head assembly rather than a separately serviceable consumable. Most aftermarket suppliers follow this model. Digiprint USA stocks the damper separately because replacing the damper at every head installation (without needing to purchase a full new head) is standard maintenance practice, and because damper failure alone — independent of head condition — is a common cause of starvation and banding on these platforms. Is this damper compatible with both 35pl and 50pl SPT510 variants?The SPT510 damper (VUTEk 45094578) corresponds to the IRH1513D series printhead used in both 35pl and 50pl configurations. Contact us to confirm fitment for your specific SPT510 variant and printer model before ordering, as the 35pl and 50pl may use slightly different supply system configurations depending on the printer manufacturer. Do you ship SPT510 dampers to Latin America?Yes — same day shipping from our Doral, Miami FL warehouse. Ideal for Latin American VUTEk QS, Infiniti, Icontek, and Speedvision grand-format operations using freight forwarders in the Doral area.
