Genuine HP DesignJet inks and printheads for HP Designjet T1300. Key SKUs include C9370A, C9371A, C9372A, C9373A, C9374A, C9403A. Always match the HP cartridge number (for example 711, 712, 727, 728, 730 or 746) to your plotter.
HP DesignJet plotters use ink series numbers (711, 712, 727, 728, 730, 746 and others) plus full HP SKUs such as C9370A, C9371A, C9372A, C9373A, C9374A, C9403A. Capacities in this collection include 130ml. Printheads (for example HP 729) are separate from ink — replace the head only when banding persists after cleaning.
Match your plotter badge exactly: a T520 takes 711 ink, while T940 / T1600 / T1700 use 730, and Z6 / Z9+ use 746. Rainbow Sales lists genuine HP cartridges with the OEM code in the title so CAD and GIS teams can reorder from the empty carton without guesswork.
