Brother Printers BLACK STANDARD YIELD TONER CARTRIDGE, UP TO 3,000 PAGES.

What “Up to ~3,000 pages” cartridges are designed to offer

Standard page yield (~ 3,000 pages at 5% coverage): This means under “normal” printing conditions (light text, ~5% page coverage), the cartridge can print about 3,000 pages before running out. 

Monochrome (black) laser printing: These cartridges are for black‑and‑white printing — ideal for text documents, invoices, letters, reports, etc.

Compatibility with specific printers: “Standard‑yield” cartridges are built for certain laser printer models; you must get a cartridge that matches your printer model for proper fit and operation. 

Separate drum & toner system (in some printers): Some standard‑yield cartridges are part of a design where the toner cartridge and drum unit are separate — meaning you change toner several times before needing to change the drum. This can reduce long-term printing costs. 

Sharp, consistent print quality: Even though they’re “standard yield,” many are designed to deliver professional‑quality black text — crisp and legible — suitable for business or daily office use. 

Affordability / moderate cost-per-page: Standard‑yield cartridges balance capacity and cost: they are typically cheaper than high-yield / high-capacity cartridges, making them more economical for moderate or occasional printing jobs.

Ease of installation / “plug-and-play” cartridge replacement: These toner cartridges are designed for straightforward installation — you slot them into compatible printers, with minimal effort. 

ISO/IEC standards for page yield: Cartridge yield estimates are usually based on standardized testing (for example, 5% coverage of A4 pages) — so “up to 3,000 pages” reflects a measured standard, not arbitrary marketing.
