High-Yield Yellow Ink Cartridge

This LD Products cartridge replaces the HP 727XL B3P21A and delivers a 4000-page yield for DesignJet wide-format printers. It is a professionally remanufactured unit filled with 130ml of dye-based yellow ink. The cartridge suits print shops, architects and engineers who produce large volumes of colour plans and graphics. Buyers who need pigment-based inks for outdoor signage or archival documents should look elsewhere.

Smart-Chip Page-Count Limit

An electronic smart chip tracks consumption and reports remaining ink to the printer, but it locks the cartridge once the ISO IEC 24711 rated 4000 pages are reached. The chip cannot be reset, so the unit must be replaced even if a small amount of ink remains. Users who refill their own tanks or use continuous-ink systems will find this cartridge incompatible with that workflow.

Remanufactured Shell With 24-Month Shelf Life

The recycled HP housing is cleaned, tested and refilled to meet a 18-24 month shelf life when stored correctly. Standard DesignJet ink slots accept the cartridge without adapters, and the smart chip seats firmly for reliable level readout. Shops that stock multiple spares should rotate inventory to stay within the recommended storage window.

Questions about this item

Is this the high-yield 130 ml yellow cartridge or a standard-capacity one?

Will I actually get close to 4000 pages on my DesignJet T2500?

The 4000-page figure follows ISO IEC 24711 testing; real-world yield varies with page coverage, print mode and ambient conditions.

Does the smart chip work with the printer firmware to show accurate ink levels?

Yes, the electronic smart chip provides accurate ink-level readouts and continuous print-quality adjustments on compatible DesignJet models.
