Patent ID: 7753483

Claim:
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; a longitudinal extending fluid transfer member, the fluid transfer member being configured to support the at least two printhead integrated circuits, wherein the fluid transfer member includes a plurality of chambers which are in fluid communication with a supply of printing fluid and respective ports of each printhead integrated circuit to thereby provide printing fluid to the nozzles for printing; and an electrical connector for receiving electrical signals for the at least two printhead integrated circuits; a drive electronics part incorporating at least one controller, which is connected to at least one of the at least two printhead integrated circuits via the electrical connector, for receiving compressed page image data, for decompressing the compressed page image data and for controlling the printing operation of at least one of the at least two printhead integrated circuits; and a casing part for supporting the drive electronics part and the at least one printhead module, the casing part incorporating a clamping arrangement for removably clamping the at least one printhead module to the casing part, the clamping arrangement allowing movement of the at least one printhead module relative to the casing during operation of the printhead assembly.
