Questions about this item

Which HP DesignJet models accept the 728 130-ml Matte Black cartridge 3WX25A?

The cartridge works with the HP DesignJet T730 Printer and the HP DesignJet T830 Multifunction Printer.

Will the dye-based ink in this 130-ml cartridge mix safely with pigment inks already installed in the printer?

This cartridge contains dye-based ink; mixing ink types is not supported and can cause printhead damage.

How can I verify the 6 pl drop size is firing correctly after installing the 728 Matte Black cartridge?

Run the printer's built-in printhead alignment and nozzle check; a clean pattern with no gaps confirms proper drop placement.
