Inkjet pagewidth printer for high volume pagewidth printing
First Claim
1. An inkjet printer for high-volume pagewidth printing comprises a support structure;
- a platen assembly positioned in the support structure, the platen assembly defining a pagewidth printing zone;
a print assembly positioned operatively with respect to the platen assembly, the print assembly comprising a chassis that is mounted on the support structure to span the printing zone;
a plurality of printhead modules positioned on the chassis, each printhead module having a carrier, a printhead chip mounted on the carrier and a flexible printed circuit board connected to the chip to provide the chip with control signals, the printhead modules being positioned so that the printhead chips overlie the printing zone; and
a plurality of printed circuit boards mounted on the chassis, each printed circuit board having control circuitry that is connected to a predetermined number of printhead chips; and
a feed mechanism for feeding print media through the printing zone, over the platen assembly.
