ABSTRACT:
A printhead assembly includes a printhead module including two or more printhead integrated circuits and an electrical connector for connecting electrical signals to the printhead integrated circuits. First and second power supplies are provided at first and second ends of the printhead assembly, the second end being opposite to the first end. The printhead assembly further includes a plurality of electrical conductors for providing power to the printhead integrated circuits from the first and second power supplies. The plurality of electrical conductors extend transverse to a media feed path defined through the printhead assembly. The plurality of electrical connectors are arranged as first and second groups of electrical conductors, the first and second groups having a 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. 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.
