Lexmark 78C0D10 Black Developer Unit toner cartridges (genuine brands)

Genuine Lexmark Black Developer Unit

The Lexmark 78C0D10 is a new genuine black developer unit designed for Lexmark laser printers. It supports the MC2640adwe, C2325dw, MC2325adw, MC2425adw and MC2535adwe series. This single unit delivers a typical print yield of 125000 pages. It is intended for offices that require consistent monochrome output from compatible hardware.

Integration with compatible Lexmark printers

The developer unit installs directly into the listed Lexmark models without additional adapters. It works alongside the toner cartridge and imaging components already present in the printer. Using a genuine unit maintains the designed print quality and reliability for the MC2640adwe, C2325dw, MC2325adw, MC2425adw and MC2535adwe series. No extra configuration is required beyond standard printer maintenance procedures.

Sustained output over high page volumes

With a rated yield of 125000 pages, the unit is built for extended print runs rather than short bursts. It maintains consistent black density across large jobs on the supported Lexmark printers. The developer unit replaces the original component when print quality indicates wear. It is not suited for printers outside the MC2640adwe, C2325dw, MC2325adw, MC2425adw and MC2535adwe series.
