Seiko SPT 510 / 35pl Printhead | IRH1513D Industrial Inkjet Printhead

Product Description

Seiko SPT 510 / 35pl Printhead (IRH1513D-3322). 510 nozzles, 71.8mm width, steel-plate protection. A rugged industrial inkjet printhead alternative to the i3200 Epson or HP printer head.

Seiko SPT 510 / 35pl Printhead | 71.8mm Industrial Inkjet Printhead

The Seiko SPT 510 / 35pl Printhead is a highly reliable industrial inkjet printhead known for its ruggedness and high-speed performance. Designed by Seiko Instruments (SII) in Japan, it features a drop-on-demand shear-mode piezo mechanism that ensures stable ink flow. While a compact i3200 epson is typically used for light-duty DTF or eco-solvent applications, the SPT 510 printhead is built to handle the harsh, aggressive solvent and UV inks required for grand-format outdoor advertising.

Equipped with 510 active nozzles and a 35pl droplet volume, this printer printhead delivers strong ink coverage and high-resolution output up to 720 dpi. Its steel-plate nozzle protection gives it a significantly longer service life—lasting 4 to 5 times longer than many common 128-nozzle printheads, and far outlasting a standard epson print head or hp printer head in heavy solvent environments. It supports oil-based, UV, and solvent inks, making it ideal for signage and vehicle wraps. Its wide 71.8mm print width reduces the number of printheads needed to build a print bar, simplifying machine design for OEMs building large format printhead systems.

The current IRH1513D-3322/3311 printhead is the direct replacement for the earlier IRH1513D-1321 version. It is universally compatible with grand-format digital printers, including Infiniti printers FY-3206, EFI Vutek, Roland, Gongzheng, and Icontek models.

Key Advantages of Seiko SPT 510 / 35pl Printhead

✔ Drop-on-Demand Shear-Mode Piezo

Shear-mode piezo inkjet printhead technology ensures stable, consistent jetting throughout long, continuous production runs without the fatigue issues of thermal heads.

✔ 35pl Droplet for High Coverage

A 35pl drop size delivers strong, heavy ink coverage. This provides a highly practical balance between fine detail and rapid production speed for outdoor viewing distances.

✔ Aggressive Solvent & UV Compatibility

Runs harsh solvent and UV inks reliably—fluids that would quickly degrade a standard consumer hp printer head or unmodified epson print head. Ideal for vehicle wraps and outdoor banners.

✔ Automatic Temperature Adjustment

Features automatic firing voltage adjustment for temperature variations. This keeps output stable and prevents misfires even in changing workshop conditions.

✔ 4-5x Longer Service Life

Proven Seiko reliability with rugged steel-plate nozzle protection. This printer printhead lasts 4-5 times longer than standard 128-nozzle heads, drastically reducing downtime.

✔ Wide 71.8mm Print Width

Significantly wider than desktop formats. Fewer printheads are needed per print bar, simplifying large format printhead system design and reducing overall machine costs for OEMs.

Seiko SPT 510 / 35pl Printhead FAQ

The Seiko SPT 510/35pl industrial inkjet printhead is used in grand-format solvent and UV printers for producing high-volume signage, outdoor advertising billboards, vehicle wraps, and lightbox graphics.

The i3200 epson and standard hp printer head are designed for light-duty, low-viscosity inks in scanning desktop or mid-format machines. The SPT 510 is a heavy-duty printer printhead with a steel-plate nozzle guard. It handles highly aggressive solvent and UV inks that would quickly destroy a standard epson print head, and lasts 4-5 times longer than typical consumer heads.

The SPT 510/35pl inkjet printhead has 510 active nozzles arranged across a wide 71.8mm print width. This gives a native resolution of 180 dpi, capable of achieving up to 720 dpi with multi-pass printing.

Yes. The IRH1513D-3322 and IRH1513D-3311 are the current generation parts that directly replace the older IRH1513D-1321. They offer the same footprint, 35pl drop volume, and 510-nozzle configuration, dropping seamlessly into existing printer designs.

The SPT 510/35pl supports oil-based inks, UV-curable inks, and aggressive solvent inks. Its shear-mode piezo design and rugged construction make it uniquely suited for these heavy fluid chemistries.
