HP 91 Ink Cartridge - Black

This cartridge is specifically designed for the HP DesignJet Z6100 printer model.

This cartridge uses a pigment-based ink, which provides enhanced durability, water resistance, and fade resistance compared to dye-based inks.

The HP 91 Photo Black ink cartridge contains 775 ml of ink.

The Photo Black cartridge is ideal for printing high-quality photographs and images where rich, deep blacks and precise tonal gradations are essential. It is optimized for photo papers.

It is strongly recommended to use only Original HP ink cartridges with your HP DesignJet printer to ensure optimal performance, print quality, and to avoid potential damage or compatibility issues.

Store unused cartridges in their original packaging at room temperature (15-35°C or 59-95°F) in a dry place, away from direct sunlight and extreme temperatures.

'Standard Yield' indicates the expected page yield or print volume under typical usage conditions. For professional large-format printing, this refers to the amount of ink available for large prints rather than standard document pages.

Ensure the cartridge is correctly seated in its slot. Remove and reinsert it firmly. Check the electrical contacts on both the cartridge and the printer carriage for any smudges or debris; clean gently with a lint-free cloth if necessary. Verify that you are using a genuine HP cartridge compatible with your printer model.

Run the printer's built-in cleaning utility. Perform a printhead alignment. Check the ink levels for all cartridges, as low levels in other colors can sometimes affect overall print quality. Ensure the correct paper type is selected in the print driver.

Refer to your HP DesignJet printer's manual for specific error code meanings. Common solutions include reseating the cartridge, cleaning contacts, or replacing a faulty cartridge if indicated.
