Three-Pack Extra-High-Yield Toner

This pack contains three LD Products compatible black toner cartridges that replace Dell part numbers 331-8429 and W8D60. They are built for Dell Color Laser printers C3760dn, C3760n and C3765dnf purchased in the United States or Canada. Each cartridge delivers a rated yield of 20,000 pages measured under ISO/IEC 24711 at five percent coverage.

Sustained-Print Consistency

The extra-high-yield formulation is designed to maintain density and sharpness across long print runs rather than only in short bursts. Cartridges are engineered to the same page-yield standard as the original Dell supplies, so office workflows that print hundreds of pages daily see stable output without frequent swaps.

Upgrade From Standard-Yield Cartridges

This set replaces the lower-capacity Dell 331-8425 and 331-8421 black cartridges, cutting the number of interventions needed for the same volume. The jump is worthwhile for departments that regularly exhaust standard cartridges and want fewer change-outs per quarter.

Questions about this item

Does the 20000-page yield rating change if the printer runs continuously all day?

The 20000-page figure follows ISO/IEC 24711 at 5% coverage; continuous printing does not alter the rated yield, though actual pages may vary with job mix and coverage.

Must the Dell C3760dn, C3760n or C3765dnf already be installed and working before these cartridges are used?

Yes — the 3-pack replaces Dell 331-8429 W8D60 black toner and only functions in those three Dell Color Laser models purchased in the United States or Canada.

Will these cartridges work in an older Dell 331-8425 or 331-8421 standard-yield slot?

They are the extra-high-yield version of 331-8425 and 331-8421 and fit the same Dell C3760 and C3765 printers, but the printer must be a US/Canada model.
