Printhead system with common electrical connector for power and data signals

摘要

A printhead system is provided comprising at least one printhead module comprising at least two printhead integrated circuits, each of which has nozzles formed therein for delivering printing fluid onto the surface of print media, a support member supporting and carrying the printing fluid for the at least two printhead integrated circuits, and at least two electrical connectors for connecting electrical signals to the respective ones of the printhead integrated circuits. The system further comprises drive electronics incorporating at least one controller for controlling the printing operation of at least one of the printhead integrated circuits, and a casing in which the printhead module and drive electronics are removably mounted. Each of the electrical connectors is arranged to direct control signals from the controller to the corresponding printhead integrated circuit and to direct power from a power supply to the corresponding printhead integrated circuit and the drive electronics.
