3.1 Overview

The OPC Drum Unit is a user-replaceable consumable. It has a life of around 30,000 pages. It receives
the laser light image of the page from the LSU, transfers toner from the developer to the OPC drum to
form this image, and allows the toner image to be transferred to the page prior to fusing. See Figure 3–1.
This unit is factory assembled and factory adjusted. No field adjustments are required.
