Konica minolta Toner TN311 – BH350

The Konica Minolta TN-311 (part number 8938402) is the Black toner cartridge designed for the monochrome (black and white) bizhub 350 and 250 office copier engines.

Compatible Konica Minolta Printer Series:

• bizhub 250

• bizhub 350

Technical Specifications:

• Part Number: TN-311 / 8938402.

• Page Yield: Approximately 17,500 pages (calculated based on standard 5% page coverage).

• Color: Monochrome (Black).

Key Information:

• Legacy Design: This is a classic, durable plastic toner bottle that locks into place horizontally via the front panel. It uses a mechanical dispensing mechanism rather than the complex electronic chip structures seen on later bizhub platforms.

• Simitri Polymerized Toner: Even as an older monochrome series, this cartridge uses Konica Minolta’s Simitri polymerized toner. The uniform, spherical shape of the particles ensures fine text rendering, sharp lines for charts, and a clean matte finish.

• Included Components: Genuine manufacturer boxes for this part number typically bundle two toner bottles per box along with a replacement waste toner bag, offering a combined box yield of roughly 35,000 pages.

• Separate Wear Parts: For maintaining solid black density and background-free prints, monitor the separate DR-310 Drum Unit (~80,000 pages) and the DV-310 Developer (~80,000 pages), which handle image transfer and must be replaced independently of the toner bottle.
