Abstract

A consolidated page-wide array of jetting modules adapted to move between an operative position in which the face of the array is parallel and proximate to the printing medium and a maintenance position in which it is not. While in the maintenance position, the PWA may be maintained by applying the actions maintenance modules of a maintenance station. Modules include a capping module for purging and priming the jetting modules with solvent, a wiping module for wiping the solvent from the face plates of the jetting modules and a sponging module for removing any excess solvent. The maintenance station may be moved into position while the PWA is in the maintenance position and the maintenance modules may be individually positioned relative to the face of the PWA in order to perform their respective tasks. Sensors to identify the position of the PWA and the maintenance station may permit automated control of the maintenance operation. Neither the PWA nor the printing medium need to be removed in order to maintain the PWA.
