Brother LC1100Y is a genuine yellow ink cartridge for compatible Brother inkjet printers. It is sold as a single cartridge and has a verified yield of 325 pages. Brother documentation confirms the LC1100Y reference and lists compatible models including DCP-385C, DCP-395CN, MFC-490CW, MFC-6890CN, and MFC-795CW. This is the right choice for customers replacing the yellow cartridge in an LC1100-based printer setup and who need a direct OEM replacement without changing the full ink set.
