Abstract:
1. A rotary inkjet imaging apparatus for imaging a page of media having a length and width dimension held stationary during imaging in a curved configuration defining a curved print zone having a longitudinal axis, comprising: a carrier assembly including a carrier; a plurality of inkjet printheads rotatably supported by said carrier for undergoing multiple winding movements at a rotation speed within said curved print zone about a central axis extending parallel to said longitudinal axis so that each printhead moves in a generally helical path of movement about the central axis and each inkjet printhead images an entirety of the page of media while moving across the length and width dimensions of the stationarily held page of media in a single pass of the carrier that moves at an advance speed through the curved print zone, each of the plurality of inkjet printheads having pluralities of nozzles for ejecting ink and a respective ink cartridge; and control circuitry to coordinate the rotation speed and the advance speed to adjust a printing time per page according to predetermined image quality requirements for said imaging.
