Printer Subsystem Overview
The printer is made up of eight major subsystems, which are described in this
section:
■ Process Drive
■ Media Drive
■ Ink Loader
■ Printhead
■ Drum Maintenance Kit
■ Purge System
■ Drum Assembly and Transfix Assembly
■ Electronics Module
The Process Drive:
Transmits torque to two camshafts. The Transfix Camshaft
controls the Transfix Roller loading, and the Drum Maintenance Camshaft
actuates the Drum Maintenance Kit and Printhead tilt system.
The Media Drive: Controls each roller in the media transport path. The Media
Drive consists of a drive motor, a gearbox, two clutches, and a solenoid. The
Media Drive motor also controls the movement of the Wiper Blade and
headlock mechanism through a gear train and solenoid on the Exit Module.
