An ink jet maintenance station for an ink jet printer with radially arranged printheads around a print drum. The maintenance station is located axially outward of the print drum, and includes a cylinder with caps and wipers at the cylinder periphery. A cam system operates upon rotation of the cylinders to elevate the caps into sealing relationship with the printhead nozzle plates. The nozzle plates are wiped by rotation of the cylinder to sweep the wipers across the nozzle plates. During non-service periods, the maintenance station does not interfere with printer carriage movement.
