Ricoh M875-12 Color Drum Unit SP C430

Ricoh M875-12 Color Drum Unit SP C430 is the color photoconductor drum (PCDU) used in Ricoh’s SP C430 family to form the imaging surface for one color channel in the four‑color output. Compatible models include Ricoh Aficio SP C430, SP C430DN, SP C431, and SP C431DN, with each color drum unit handled separately within the color set. The M875-12 designation appears in catalogs alongside related part numbers such as 407019, 406663, and M87512, reflecting its role as the color drum unit for one color in the SP C430 system. The unit is rated to yield about 50,000 pages per color (ISO/IEC 19798), providing durable performance for color printing in office environments. As a replaceable drum cartridge, it is designed to be swapped when color density or consistency begins to degrade. This description refers to the color drum unit component itself rather than toner, fuser, or other consumables, and is intended for users maintaining SP C430‑series devices.
