Abstract:
1. A printhead assembly, 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, one support member supporting, and carrying the printing fluid for, the at least two printhead integrated circuits, and at least two flexible printed circuit boards for connecting electrical signals to the at least two printhead integrated circuits, each flexible printed circuit board having a connecting portion; drive electronics incorporating a plurality of controllers, at least one controller being connected to at least one of the at least two printhead integrated circuits via the respective flexible printed circuit board for controlling the printing operation of at least one of the at least two printhead integrated circuits; and a casing in which the at least one printhead module and the drive electronics are removably mounted, wherein each controller and the associated drive electronics is provided on a associated printed circuit board carrying respective slotted connection ports for receiving, and connecting with, the corresponding connecting portions of the flexible printed circuit boards, the connecting portions being configured to slot within the slotted connection ports so that the printhead integrated circuits of the at least one printhead module are aligned with the respective controller, the printed circuit boards being adjacent one another and each having recessed portions which adjoin recessed portions in the adjacent printed circuit boards, said adjoined recessed portions receiving an electrical connecting member for interconnecting the controllers of adjacent printed circuit boards such that each interconnected controller is able to control the printing operation of the at least two printhead integrated circuits.
