Patent ID: 8668302

Claim:
An inkjet printer comprising: a frame; a plurality of color separation modules mounted within the frame, each color separation module of the plurality of color separation modules including an image receiving member and a printhead module configured to eject ink drops onto the image receiving member to form an ink image on the image receiving member; a media transport system configured to move a print medium past the plurality of color separation modules; a plurality of fixing members, each fixing member being positioned adjacent to one of the image receiving members to form a plurality of nips into which the media transport system delivers the print medium, the nips being configured to transfix the ink image from each of the image receiving members onto the print medium; a first sensor configured to generate a signal indicative of a position of the print medium prior to the print medium entering the plurality of nips, and a controller operatively connected to each of the color separation modules, the media transport system, and the first sensor, the controller being configured to: detect the position of the print medium with reference to the signal generated by the first sensor; and operate the plurality of color separation modules to synchronize entry of the ink image on each image receiving member with entry of the print medium into each nip with reference to the detected position of the print medium to generate a full-color ink image on the print medium.
