Compatible Magenta Cartridge for Dell 1250C Series

This magenta toner cartridge replaces Dell 331-0780 and fits the 1250C, 1350CNW, 1355CN, 1355CNW, C1760NW, C1765NF and C1765NFW printers. It is an aftermarket alternative designed for users who need a direct replacement for the original magenta supply. The single pack suits home offices or small businesses running one of the listed Dell colour laser models.

Consistent Output Across 1400 Pages at Five

The cartridge is rated for 1400 pages at five percent coverage, reflecting sustained yield rather than a short-run figure. Operating between 10 and 32.5 degrees Celsius with humidity from 20 to 80 percent RH, it maintains print density through a full job without the drop-off sometimes seen in brief test prints. Storage tolerances from minus 20 to 40 degrees Celsius protect shelf life between uses.

Drop-In Fit With Standard Dell Slot Geometry

The unit follows the Dell 331-0780 form factor, so it seats in the existing magenta slot without adapters or force. No extra mounting hardware is required and the cartridge ships with installation notes inside the protective packaging. Buyers who need a black, cyan or yellow cartridge for the same printer must purchase those colours separately, as this pack contains only the magenta unit.
