Compatible Black Toner for Dell C3760 Series

This True Color Toner cartridge replaces Dell OEM numbers 331-8421, 331-8425 and 331-8429. It fits Dell C3760, C3760DN, C3760N, C3765 and C3765DNF printers. The single black cartridge suits offices that need consistent monochrome output without paying OEM prices.

Steady Output Across High Volume

Rated at 11000 pages at five percent coverage, the cartridge is built for sustained print runs rather than occasional pages. Print density stays uniform from the first sheet to the last, reducing reprints on long reports or batch jobs.

Drop-In Fit With Quality Assurance

The moulded shell aligns with the Dell chassis so installation takes seconds and the printer recognises the cartridge immediately. Each unit passes SMTC and ISO quality checks and carries a one-year manufacturer defect guarantee for day-to-day reliability.

Questions about this item

Does the True Color Toner 3760 black cartridge run hot or draw extra power during long print runs?

Toner cartridges are passive components; they generate no heat and consume no power beyond what the Dell C3760, C3760DN or C3760N printer already uses.

Which Dell printers must I already own for this 331-8421 replacement to work?

The cartridge fits Dell C3760, C3760DN, C3760N, C3765 and C3765DNF models.

Will this high-yield 11000-page black toner work alongside the colour cartridges already in my C3760DN?

Yes, it replaces OEM numbers 331-8421, 331-8425 and 331-8429 and operates normally with the existing cyan, magenta and yellow cartridges.
