CZ679A - HP Latex 831 printhead (Light Cyan/Light Magenta)

CZ679A – HP 831 Latex printhead – Light Cyan / Light Magenta

The HP 831 Latex Light Cyan / Light Magenta printhead (CZ679A) is a key part of the print carriage on HP Latex 300 and 500 series printers.

It lays down the Light Cyan and Light Magenta inks needed to reproduce subtle gradients and skin tones faithfully. Using HP Thermal Inkjet technology with high-density nozzles, it jets very small droplets with micrometric precision.

Supplied as a new genuine HP part, the CZ679A fits directly into the machine carriage. It must be used with HP 831 Latex Light Cyan and Light Magenta ink cartridges and realigned per the manufacturer procedure after installation.
