Abstract

A printer cartridge for an inkjet printer including a printing fluid storage and a pagewidth printhead in fluid communication with said printing fluid storage, said printhead including two print chips which extend the length of the printhead.

Claims (8)

1. A printer cartridge comprising:

a body configured to facilitate insertion and removal of the printer cartridge, by an end user of the printer cartridge, to and from a complementary cradle in an inkjet printer;

printing fluid storage mounted to the body;

a pagewidth printhead mounted to the body for printing a media substrate when inserted in the complementary cradle, the pagewidth printhead having a first print chip and a second print chip, the first print chip having an array of nozzles fabricated on a first monolithic substrate and the second print chip having an array of nozzles fabricated on a second monolithic substrate that does not include the first monolithic substrate, the length of the first print chip added to the length of the second print chip is at least equal to the length of the pagewidth printhead; and,

a fluid connection between the printing fluid storage and the first and second print chips; wherein,

the pagewidth printhead and the printing fluid storage are mounted to the body such that removal and replacement of the body by an end user of the printer cartridge simultaneously removes and replaces the printing fluid storage, the pagewidth printhead and the fluid connection.

2. A printer cartridge according to claim 1 wherein the first and second print chips abut together to extend the length of the printhead.
