Inkjet print assembly for high volume pagewidth printing
First Claim
1. An inkjet print assembly for high-volume pagewidth printing, the print assembly being configured for mounting on a support structure within a printer, in use the assembly being positioned operatively with respect to a platen assembly that defines a pagewidth printing zone, and a feed mechanism for feeding print media through the printing zone over the platen assembly, the print assembly comprising:
- a chassis for mounting the print assembly 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 consecutively along the width of the printing zone so that the printhead chips overlie the printing zone; and
a plurality of print controllers, each print controller being connected to a predetermined number of the printhead chips, configured to process print data and control the predetermined number of printhead chips to print the processed print data, and mounted on one of a plurality of printed circuit boards mounted on the chassis.

Abstract
An inkjet print assembly for high-volume pagewidth printing is attached to a support structure within a printer. In use the print assembly is positioned operatively with respect to a platen assembly also located in the support structure, the platen assembly defining a pagewidth printing zone. The print assembly includes a chassis that is mounted on the support structure to span the printing zone. A plurality of printhead modules is positioned on the chassis. Each printhead module has 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 are positioned so that the printhead chips overlie the printing zone. A plurality of printed circuit boards is mounted on the chassis. Each printed circuit board has control circuitry that is connected to a predetermined number of printhead chips. The printer includes a feed mechanism for feeding print media through the printing zone, over the platen assembly.
