The HP W9133MC magenta managed LaserJet toner cartridge supplies magenta toner for compatible colour printing. It is the high-yield magenta member of the W9130MC–W9133MC cartridge family, whose other cartridges provide black, cyan and yellow.
The stated yield is about 20,000 pages, measured according to ISO/IEC 19798. Actual use varies with printed content, but this page-yield figure helps describe the cartridge’s rated output for print planning.
It is listed for the HP Color LaserJet Managed MFP E785dn, E78523dn and E78528dn. Magenta toner contributes to red and violet tones, as well as some blue shades in colour documents and graphics.
