Genuine HP 711 Black Ink Cartridge

The HP CZ129A is a genuine 38-ml black ink cartridge built for HP DesignJet T100, T120, T125, T130, T520, T525 and T530 printer series. It uses dye-based ink with a 12 pl drop size to produce sharp lines down to 0.0008 inch for technical drawings and GIS maps. AEC students, professionals and small workteams rely on it for consistent, accurate output.

Simple Front-Access Installation

The cartridge slides into the front-access slot on compatible DesignJet printers without tools or firmware steps; the printer recognises it immediately and primes the printhead automatically. Because the ink is formulated as an optimised system with the printer, clogged nozzles and colour shifts are rare when the unit is stored within the specified 10 to 90% RH range. Problems usually appear only if the cartridge sits unused past its shelf life or is exposed to temperatures outside the 41 to 95°F operating window.

38-ml Capacity for Low-Volume Work

At 38 ml the black cartridge suits low-to-moderate print volumes such as check plots, presentation sheets and student projects; it will run out quickly on high-coverage posters or continuous batch printing. For heavier workloads the 80-ml black option or colour 3-packs provide more headroom, while the 29-ml colour cartridges match this black unit for balanced colour jobs. Users printing daily high-density graphics should expect more frequent replacements.

Questions about this item

How do I confirm the HP 711 38-ml Black DesignJet Ink Cartridge CZ129A is printing correctly after installation?

Print a test page and verify sharp lines down to 0.0008 inch minimum width with consistent black density; the 12 pl dye-based ink drop size should produce accurate detail on compatible DesignJet T100, T120, T125, T130, T520, T525, or T530 series printers.

What comes in the box with the HP 711 38-ml Black DesignJet Ink Cartridge CZ129A and what must I buy separately?

The box contains the single 38-ml black cartridge; color cartridges (29-ml each) and any 80-ml high-volume black or 3-pack color options are sold separately for the DesignJet T100, T120, T125, T130, T520, T525, T530 series.

Which HP 711 cartridge capacity should I choose for my DesignJet printer — 38-ml black, 29-ml color, or 80-ml black?

Choose the 38-ml black CZ129A for standard monochrome volume; add 29-ml color cartridges for colour work; select 80-ml black only if your T100, T120, T125, T130, T520, T525, or T530 series runs high print volumes.
