HP F9K15A 728 Yellow 300-ml ink cartridges (genuine brands)

HP 728 Yellow 300-ml DesignJet cartridge

The HP F9K15A is a genuine 300-ml yellow ink cartridge for HP DesignJet T730 and T830 printers. It supplies dye-based ink with a 6-pl drop size for crisp CAD and general-purpose output. Design and engineering workgroups use it to maintain consistent colour accuracy across high-volume print runs.

Thermals noise and power draw

As an ink cartridge the unit has no moving parts, fans or power consumption of its own. It operates reliably between 41 and 104 °F and can be stored from -13 to 131 °F at 20 to 80 % relative humidity. The printer manages all thermal and acoustic behaviour during printing.

Upgrade from smaller cartridges

This 300-ml cartridge replaces the 40-ml size in the same HP 728 series, reducing the frequency of swaps during long unattended jobs. The jump is worthwhile when print volumes justify the higher capacity and fewer interruptions are needed. Buyers who need multiple colours in one pack or a different ink formulation will not be served by this single yellow unit.
