Why choose the genuine HP 728 ink cartridge
Genuine HP 728 ink formulated for the printheads and media of HP DesignJet plotters: fine lines, stable colors, fast drying, no clogged nozzles. Genuine HP formulation for sharp, durable output. The 130 ml cartridge is detected automatically; the plotter tracks the real level and warns before it runs out.
Volume and printheads
130 ml cartridge; the HP 728 series also comes in 300 ml. The ink is fired by the plotter's printhead, replaced only when the machine asks for it.

The F9J66A is compatible with 8 HP models (manufacturer list):

The series listed include all their variants (24, 36 or 44 inch, PostScript, multifunction); check the HP number of your current cartridges on the plotter's display.
Ink and consumption
130 ml of genuine HP ink; consumption depends on media, coverage and the plotter's quality mode.
Installation and maintenance
Install the cartridge in its color slot with the plotter on; it locks by itself and the level appears on the display. Remove a cartridge only to replace it; opened cartridges keep inside the plotter. Free recycling through HP Planet Partners.
Use and tips
For design offices, architects, surveyors and reprographics departments: plans, maps, posters and renderings on plain, coated or photo paper. The plotter manages levels and warns ahead of an empty cartridge; keep one cartridge of each color in reserve so a plot is never interrupted.
Store cartridges in their packaging between 15 and 35 °C, away from sunlight; install them before the date printed on the box. Leave the plotter powered: it maintains its printheads automatically. Genuine HP ink protects the printheads and the plotter's warranty.
