HP 746 Magenta Cartridge For DesignJet Z6 And Z9
This genuine HP 746 ink cartridge holds 300 ml of magenta pigment-based ink. It is engineered for the HP DesignJet Z6 and Z9 printer series used by print service providers, GIS map creators and retailers. The formulation works with HP Vivid Photo Inks and printheads to produce water- and fade-resistant output. Buyers needing a different colour or a smaller capacity cartridge will need a separate item.
Operating Range 68 To 77 Degrees Fahrenheit
The cartridge is rated for use between 68 and 77 degrees Fahrenheit at 40 to 55 percent relative humidity. It can be stored from minus 40 up to 140 degrees Fahrenheit at 8 to 90 percent humidity. Pigment-based ink remains stable across these ranges, helping maintain consistent flow and colour density during long print runs. Extreme conditions outside these limits may affect reliability.
RGB Ink Set Reduces Cartridge Count
The magenta cartridge is part of an RGB HP Vivid Photo Ink set that expands the colour gamut while using fewer individual inks. This design helps lower per-page printing costs and reduces the environmental footprint of high-volume graphics work. Prints produced with the full set are rated to last over 200 years in dark storage. Compatibility with the RGB ink set is limited to the HP DesignJet Z9 PostScript printer series.

Questions about this item
How do I install the HP 746 300-ml Magenta cartridge into my DesignJet Z6 or Z9 printer, and what step is often missed?
Open the ink carriage cover, remove the orange protective cap from the new cartridge, insert it firmly into the magenta slot until it clicks, then close the cover; the step often missed is removing the orange cap before insertion.
What maintenance or replacement will this pigment-based ink cartridge need later?
The cartridge itself is replaced when empty; the printer will eventually require printhead replacement to maintain the 200-year fade resistance, and the waste ink tank may need service.
What is the first limit I will hit under sustained printing with this cartridge?
The 300-ml ink volume will deplete first, requiring a new cartridge; continuous operation also requires the ambient temperature to stay between 68 and 77°F and humidity between 40 and 55% RH.
