Confirmed by STS for Chinese-brand wide-format printers such as the EJET-1801 that use GS-type ink systems. Plug and print — no flush, no profile change. Drop ships fresh from STS Florida.

Description
STS Eco-Solvent GS/GSX/GS2 Ink (GBL-Free) — Precision Replacement for GS / GSX / GS2 Printers
The STS GS/GSX/GS2 Eco-Solvent Ink (1-liter bottle) is formulated to match the color properties and performance of GS, GSX, and GS2 ink chemistries used in certain Chinese-brand wide-format eco-solvent printers. STS confirms compatibility with the EJET-1801 and similar printers using this ink type. This product is a 1-liter bulk bottle — it is not the same as the T624 (950ml cartridge for Epson Stylus Pro GS6000) or T689/T715 cartridges for Epson SureColor S-series. Confirm your printer uses GS-type bulk ink chemistry before ordering.

FREQUENTLY ASKED QUESTIONS
Frequently Asked Questions — STS Eco-Solvent GS/GSX/GS2 Ink (GBL-Free)
STS confirms this ink for Chinese-brand wide-format printers using GS-type ink chemistry, including the EJET-1801. This is a 1-liter bulk bottle format. It is NOT compatible with Epson SureColor S-series printers (which use proprietary T689/T715 drop-in cartridges) or the Epson Stylus Pro GS6000 (which uses T624 cartridges). Call (512) 454-0505 to confirm your printer before ordering.
The T624 is a 950ml proprietary drop-in ink cartridge exclusively for the Epson Stylus Pro GS6000. This GS/GSX/GS2 product is a 1-liter bulk bottle for Chinese-brand printers using GS-type ink chemistry. They are completely different products for different printers. Do not attempt to use this bulk bottle as a replacement for the T624 cartridge.
GBL stands for gamma-butyrolactone, a solvent found in many traditional eco-solvent inks that requires dedicated ventilation systems. This STS ink is formulated without GBL, making it suitable for standard indoor shop environments with basic air circulation, without special ventilation infrastructure.
No. The Epson SureColor S-series printers use proprietary drop-in cartridges — T689 (700ml, GS2) for S30670/S50670, and T715 (GSX) for S70670. These are closed cartridge systems. This 1-liter bulk bottle is not a compatible replacement for those cartridges. Confirm your printer model before ordering.
No. All STS eco-solvent inks are non-returnable. Confirm your printer model and the correct OEM ink code before ordering. Call (512) 454-0505 or email [email protected] with your printer model to confirm compatibility.
No. STS eco-solvent inks are formulated to be a virtual match to the original OEM inks. Install them exactly like OEM — no purging, no profile changes, no downtime.
All STS inks are manufactured in the USA. Orders drop ship directly from STS in Florida — you receive current-production ink, not warehouse-aged stock.
