HP 727 300-ml Gray DesignJet Ink Cartridge, F9J80A

The HP 727 F9J80A is a genuine 300 ml gray dye-based ink cartridge for users of compatible HP DesignJet printers, including the T920, T1500, T930, T1530, T2530, and T2500 eMFP series.

Recommended For

• DesignJet T920, T1500, T930, T1530, T2530, or T2500 owners replacing the gray cartridge in their printer.
• Architecture, engineering, and technical-design teams printing professional drawings who need gray ink for compatible DesignJet workflows.
• DesignJet users who print gray regularly and prefer a 300-ml cartridge to reduce how often they replace supplies compared with the 130-ml option.
• Teams producing drawings that need neutral gray output on a compatible printer in HP’s three-black ink set.

Real-World Use Scenarios

• When an architecture or engineering team prints large-format CAD plans for review, the gray ink helps render gray linework and shaded areas alongside darker black details, making drawing elements easier to distinguish.
• For teams printing batches of technical drawings, the 300-ml cartridge can reduce how often gray ink needs replacing, helping longer print runs continue with fewer supply changes.
• When preparing maps or site plans, gray backgrounds and detail layers can print alongside colored information, helping users review multiple types of map content on one large-format sheet.
• When printing grayscale technical diagrams or drawings with shaded regions, the gray cartridge helps produce tonal detail rather than relying only on solid black marks.
• In a shared office that prints plans throughout the day, users can replace the gray cartridge in a compatible DesignJet and continue producing drawings without changing the printer or its color workflow.
