Product information

Description

The KMP Toner Brother TN-421K 3000 pages Black is a remanufactured black laser toner cartridge designed for use in compatible Brother printers. It provides an estimated yield of 3000 pages and is intended to reproduce sharp text and consistent black graphics across typical office and home print jobs. As a remanufactured cartridge, it offers a cost-effective and more environmentally friendly alternative to single-use originals while maintaining compatibility with standard laser printing workflows.

Advantages

This remanufactured toner cartridge delivers reliable monochrome output with consistent density for text documents and business graphics. Because it is remanufactured, the cartridge reduces waste and lowers consumable costs compared with new original cartridges. The unit is lightweight and simple to install, and it is suitable for routine printing volumes where a 3000-page yield is appropriate.

Suitable for

  • Everyday office black-and-white documents
  • Home printing of letters, invoices and school materials
  • Business reports, forms and internal manuals
  • Low- to medium-volume printing environments

Key specifications

  • Print technology: Laser printing
  • Colour: Black
  • Estimated page yield: 3000 pages
  • Compatibility: Designed for Brother laser printers
  • Quantity per pack: 1 piece
  • Weight: 0.075 kg

How to use

Turn off the printer or switch it to standby according to the manufacturer’s instructions before replacing the cartridge. Open the printer’s toner access panel, remove the empty cartridge following the printer’s removal procedure, and unpack the remanufactured cartridge. Gently shake the cartridge side to side if recommended, remove any protective seals, and insert it into the correct slot until it clicks into place. Close the access panel and restore power; allow the printer to initialize and recognize the new cartridge. Run a test print or calibration page if available to verify correct installation and print quality.

Usage recommendations

Store the cartridge in a cool, dry place away from direct sunlight. For consistent print density, use on suitable paper types recommended for laser printing and perform regular printer maintenance such as cleaning the drum and feed rollers. Replace the cartridge when print quality degrades or toner low warnings appear. Follow local guidelines for disposal or recycling of remanufactured toner cartridges.
