Patent ID: 8162438

Claim:
A rotary inkjet imaging apparatus, comprising: a curved print zone having a longitudinal axis defined by a page of media having a length and width dimension held during imaging in a curved configuration about said longitudinal axis; a carrier assembly including a carrier movable bi-directionally along a substantially linear guide path defined adjacent to said curved print zone and extending substantially parallel to said longitudinal axis thereof; and an inkjet printhead disc having a body and at least one printhead chip on a perimeter of said body, said printhead disc body supported by said carrier for undergoing rotation about a central axis and linear movement within said curved print zone along a path parallel to said guide path and coaxial with said longitudinal axis of said curved print zone such that said inkjet printhead disc body rotates about said central axis multiple revolutions and said printhead chip prints on the page concurrently as said carrier unidirectionally moves along said linear guide path and said printhead disc body moves across the length and width dimensions of the held page of media in a single pass of the carrier within said curved print zone and carries said printhead chip through portions of said curved path in which said printhead chip faces toward the page.
