Ninestar Technology CF226X 2 Pack High-Yield Black Toner Cartridge

Two-Pack High-Yield Black Toner

This two-pack supplies high-yield black toner cartridges built to replace the HP CF226X 26X. They fit HP LaserJet Pro M402 and M426 series printers for offices that print large volumes of monochrome documents. Each cartridge is manufactured to meet or exceed the original equipment specifications for consistent output. The set delivers a lower cost per page than standard-capacity alternatives.

Operating Range 10°C to 30°C

The cartridges are rated for use between 10°C and 30°C with humidity from 20% to 80%. Storage limits extend from -20°C to 40°C at the same humidity band. Staying inside these ranges helps prevent toner clumping and maintains print density over time. No active cooling or special ventilation is required beyond normal office conditions.

Two-Year Shelf Life and Warranty Safe

Each cartridge carries a two-year shelf life, so the spare unit stays reliable until needed. The supplier confirms that using these compatibles does not void the printer's original warranty. A 30-day return window allows a full refund or free replacement if print quality falls short. Buyers who need colour output or a different page-yield class should look elsewhere.
