The Seiko SPT1020 35pl (IRH2536Q-2010) is a genuine original drop-on-demand piezoelectric grand-format printhead. Built as the physical union of two SPT510-35pl head assemblies, it delivers double the native resolution of the SPT510 — 360 dpi native vs 180 dpi — across the same 71.9mm print swathe, using 1,020 active nozzles at 8.29 kHz. With a built-in temperature detection module for automatic voltage compensation, a TICKLING anti-clog idle function, and compatibility with solvent, eco-solvent, and UV inks, it is engineered for demanding high-throughput single-pass and multi-pass grand-format production. Every SPT1020 we sell at Digiprint USA is 100% genuine original Seiko Instruments (SII) Japan.

SPT1020 vs SPT510 — Why 1,020 Nozzles Changes Everything
| Spec | SPT510-35pl | SPT1020-35pl (this listing) |
|---|---|---|
| Active nozzles | 510 | 1,020 |
| Native resolution | 180 dpi | 360 dpi — double |
| Print width | 71.8 mm | 71.9 mm |
| Drop size | 35 pl | 35 pl |
| Temperature module | No | Yes — auto voltage compensation |
| Anti-clog (TICKLING) | No | Yes |
| Interchangeable? | No — different part numbers, different printer compatibility, different mounting | |
The SPT1020 achieves 360 dpi native resolution by physically combining two SPT510-35pl head arrays in a staggered configuration — doubling nozzle density over the same print width. This makes it the choice for printers requiring higher single-pass resolution without reducing print speed or increasing the number of passes.
Built-In Temperature Module and TICKLING
The SPT1020 integrates two features absent from the simpler SPT510: a real-time ink temperature detection module that monitors thermal conditions inside the head and automatically adjusts drive voltage to maintain jetting stability across ambient temperature changes; and a TICKLING function that applies low-amplitude vibration to the nozzle array during printer idle periods, preventing ink from drying and crusting at the nozzle tips — a common failure mode in high-solvent-load environments. These features directly extend head service life in demanding production environments.

Frequently Asked Questions
What is the relationship between the SPT1020 and the SPT510?
The SPT1020 is the physical combination of two SPT510-35pl head arrays in a staggered configuration. This doubles the native nozzle count from 510 to 1,020 and the native resolution from 180 dpi to 360 dpi across the same 71.9mm print swathe. It also adds the built-in temperature detection module and TICKLING anti-clog function not present in the SPT510. They are not interchangeable — the SPT1020 uses different mounting, wiring, and printer-side drive electronics to the SPT510.
What is the TICKLING function?
TICKLING applies low-amplitude vibration to the nozzle array during printer idle periods. This prevents solvent and UV ink from drying and crusting at the nozzle tips — a primary cause of clogged nozzles after idle standby. It is an automatic function controlled by the printer system and does not require operator intervention.
What is the built-in temperature module?
The SPT1020 includes a real-time ink temperature sensor inside the head body. It monitors thermal conditions continuously and automatically adjusts the piezo drive voltage to compensate for viscosity changes caused by temperature variation — maintaining consistent drop size and jetting stability without manual recalibration across ambient temperature changes during production.
Do you ship Seiko SPT1020 IRH2536Q-2010 printheads to Latin America?
Yes — same day shipping from our Doral, Miami FL warehouse. Our Miami location is ideal for Latin American Icontek, Infiniti, and Phaeton grand-format production shops using freight forwarders in the Doral area.
