ABSTRACT:
A print engine for an inkjet printer includes an inkjet cartridge having a cartridge body, a pagewidth printhead, a capper unit extending a length of the pagewidth printhead and housing a capping element which is movable between a capped position in engagement with the pagewidth printhead and a retracted position spaced from the pagewidth printhead, and an ink supply. The cartridge body supports the pagewidth printhead, the capper unit and the ink supply for simultaneous removal and replacement as a unitary component. The print engine further includes a cradle having a body for receiving the removable inkjet cartridge and to control the operation of the printhead for printing, the cradle having a capper drive for engaging the capper unit and drawing the capping element to the uncapped position; and a print controller board received in the cradle, the print controller board including one or more electrical terminals for engaging with corresponding electrical terminals on the inkjet cartridge. The cradle is secured to the inkjet printer to receive print media from a media input tray and to deliver printed media to a media output tray via a media feed path extending between the pagewidth printhead and the capping element. The print controller board is pivotally received in the cradle to pivot into and out of contact with the corresponding electrical contacts of the inkjet cartridge in response to the actuation of a cover assembly for covering the cradle unit.
