Imaging Unit
The Imaging Unit is a customer replaceable item that carries out the charging,
development, transfer, and cleaning steps in the print process (see “Printing
Process” on page 2-3).
The Imaging Unit consists of the following items:
■ Developers
Each of the four Developers includes the Augers that distribute the toner
and the Magnet Roller that applies toner to the Drum to develop the latent
image.
■ Drums
Each drum is given a latent image to which toner is applied by the
Developer. The resulting toner image is transferred to the paper.
■ CRUM
Information specific to the Developer/Imaging unit is stored in the CRUM.
