HP 771A Matte Black DesignJet Ink Cartridge 775 ml B6Y15A

HP 771A Matte Black Cartridge 775 ml

This genuine HP 771A cartridge delivers 775 ml of pigment-based matte black ink for HP DesignJet Z6200, Z6610 and Z6810 production printers. It targets professional print shops and graphics departments that require consistent photo-quality output on indoor applications such as posters, fine art and POP displays. The 6 pl drop size supports sharp detail across a broad range of media types.

Environmental operating limits 20 to 80 percent RH

Reliable printing is specified between 64 and 77 degrees Fahrenheit with relative humidity from 20 to 80 percent. Storage tolerances extend from -40 to 140 degrees Fahrenheit and 15 to 90 percent humidity. Operation outside these ranges can cause nozzle clogging, colour shift or media handling errors that interrupt high-volume production runs.

Straightforward front-access installation

The cartridge inserts into the designated matte black slot until it clicks, and the printer primes the 6 pl nozzles automatically. Common issues include forgetting to remove the protective seal, installing the cartridge in the wrong colour position, or allowing the ink to settle after long storage beyond the recommended humidity limits.
