WorkForce ST-M
WorkForce ST-M is the monochrome branch of Epson's Supertank line for workgroups — black-only printers and MFPs that refill from the 532 ink bottle: 120 mL of pigment black (T532120), up to 6,000 pages per bottle (ISO/IEC 19752). Both ST-M models below take the same single bottle. Shop the Clever Supplies compatible 532 bottle with lifetime warranty coverage.

WorkForce ST-M Ink — The 532 Bottle for Mono Supertank Workgroups The ST-M1000 and ST-M3000 were built for offices that print nothing but documents, and their ink system is one bottle deep: Replacement Ink 532 Black (120 mL), 6,000 pages per bottle on the ISO/IEC 19752 pattern. Both models shipped with two bottles in the box — Epson markets that included ink as "up to 11,000 pages," a figure for the in-box pair after initial-fill consumption, not the per-bottle replacement rating. Replacement bottles are rated 6,000 pages each, and that is the number our product page carries.
Pigment black is the correct ink for this duty: contracts, invoices and records that stay sharp and water-resistant. And there is nothing else to buy for these machines — no colors exist in the 532 family, and the color ST models (ST-2000/3000/4000) are 502 printers with a different bottle shelf entirely.
Our compatible 532 bottle matches the official 120 mL fill and keyed fit, is chipless, and carries a lifetime warranty with 1-year free returns.
