What to know before buying

Listing details to confirm

The title names TN-880, TN-850 and TN820 compatibility, while the model details identify TN850 and TN850/TN820 and the feature text says TN-850/TN820/TN880. Compatibility should be checked against the exact printer model before purchase. The 8,000-page figure is a manufacturer claim based on 5% average coverage, and the feature text's combined-pack yield of 32,400 pages does not match four times the per-cartridge claim. The box contents field lists toner cartridge without a quantity, while the title and feature text claim a four-cartridge pack. Check the selected listing's pack quantity.

Customer feedback highlights sharp text, dark and accurate-looking output, printer recognition without error messages, and easy installation. These reported experiences matter for routine monochrome printing, but they do not establish compatibility with every model in the listing. Aggregate ratings are mostly five-star, with a notable one-star share, so experiences are not uniformly positive.
