Looking to buy an HP 975X Magenta Ink Cartridge in Australia? The HP 975X Magenta (part number L0S03AA) is a genuine HP extra-high-yield ink cartridge for the HP PageWide Pro 400 and 500 series, delivering up to 5,000 pages of rich, vibrant colour output. Whether you run an HP PageWide Pro 452dw, 477dw, 577dw, or 577z, the L0S03AA is the highest-yield genuine HP magenta cartridge for your machine — nearly double the pages of the HP 975A Magenta (L0R91AA).

What the HP 975X Magenta L0S03AA does in your printer

The HP 975X Magenta Ink Cartridge L0S03AA is the extra-high-yield magenta component for HP PageWide Pro printers, working alongside the HP 975X Black (L0S09AA), HP 975X Cyan (L0S00AA), and HP 975X Yellow (L0S06AA) to provide full-spectrum colour output at the lowest cost per page. Magenta handles the warm side of the colour spectrum — reds, pinks, and the vivid secondary tones that keep brand colours precise and customer-facing documents looking their best. At 5,000 pages per cartridge, the L0S03AA delivers consistent warm-tone accuracy at volume, with no colour drift or reduced vibrancy across its full life.

Why genuine HP 975X ink matters

Genuine HP 975X cartridges like the L0S03AA are engineered specifically for HP PageWide Pro printhead technology. Third-party and compatible alternatives for the PageWide Pro frequently cause printhead damage, inaccurate colour output, HP firmware rejection, and voided printer warranties. The genuine HP 975X Magenta L0S03AA is tested and certified to deliver consistent, vivid colour in your PageWide Pro from the first print to the final page of its 5,000-page yield.
