Konica Minolta Toner BH420 – BH501

The Konica Minolta TN-511 (part number 024B or 024E depending on the specific distribution region) is the high-yield Black toner cartridge designed for the monochrome (black and white) bizhub 420 and 501 production-class office engines.

Compatible Konica Minolta Printer Series:

This sturdy mechanical bottle features excellent backward and forward cross-compatibility across two major generations of high-volume monochrome workgroup copiers:

• bizhub 360 / 361

• bizhub 420 / 421

• bizhub 500 / 501

Technical Specifications:

• Part Number: TN-511 / 024B / 024E

• Page Yield: Approximately 32,200 pages (calculated based on standard 5% to 6% page coverage).

• Color: Monochrome (Black).

Key Information:

• Industrial Bottle Build: Given the high speeds of these engines (up to 50 pages per minute on the bizhub 501), the TN-511 is built as a thick, high-volume plastic tube containing more than 2 lbs of monochrome toner powder to satisfy major departmental workloads and lower operational costs.

• Simitri Polymerized Toner Formula: This cartridge relies on small, uniformly spherical chemical particles. Even during high-speed production runs, the chemistry minimizes background scattering, rendering clean, high-contrast text lines and highly stable halftone charts resistant to peeling.

• No Smart Chip Lockout: Unlike newer bizhub i-Series color configurations, this legacy monochrome infrastructure uses a purely mechanical layout. It monitors powder levels inside the hopper reservoir using physical sensor triggers rather than electronic contact smart chips on the bottle.

• Independent Wear Components: Solid black density and background-free prints rely on monitoring the separate underlying maintenance components. If light density or repeating line dropouts occur while a new toner bottle is heavy and full, inspect these long-life system wear parts:

  • DR-510 Drum Unit (part 024K) — Rated for up to 250,000 pages.

  • DV-511 Black Developer Unit (part 024G) — Rated for up to 250,000 pages.
