The HP 2RM82-67011 Carriage PCA is a circuit board assembly for the printhead carriage system in select HP DesignJet printers. It provides an electrical interface between the printer and the printheads in the carriage.
The board also supports communication between the carriage electronics and the printer’s control systems, and participates in the electrical functions needed by the carriage and printheads. These roles make it a service component for the printer’s carriage electronics.
The part is listed for the HP DesignJet Z6 Pro and Z9+ Pro, including their 64-inch models.
