Patent ID: 7874643

Claim:
A printhead assembly, comprising: a printhead module including two or more printhead integrated circuits and an electrical connector for connecting electrical signals to the two or more printhead integrated circuits; first and second power supplies, the first power supply being provided at a first end of the printhead assembly, and the second power supply being provided at a second end of the printhead assembly opposite to the first end; and a plurality of electrical conductors for providing power to the at least two printhead integrated circuits from the first and second power supplies, the plurality of electrical conductors extending transverse to a media feed path defined through the printhead assembly, and the plurality of electrical connectors arranged as first and second groups of electrical conductors, wherein the first and second groups of electrical conductors have combined lengths at least equal to a width of the media feed path, the first group of electrical conductors is connected to the first power supply and extends from the first end of the printhead assembly to a region intermediate the ends of the printhead assembly, the second group of electrical conductors is connected to the second power supply and extends from the second end to connect to the first group at the region intermediate the first and second ends of the printhead assembly to supply power in parallel from both ends of the printhead assembly, and the first group of electrical conductors has a staggered configuration, the staggered configuration adapted to overlap and mate with a complementary staggered configuration of the second group of electrical conductors.
