This Laser Printer creates an image on paper using a technique called laser electrophotography. The printer uses the electro-
graphic process known as Discharged Area Development, or “write black”. In this process, a digitally modulated laser scans lat-
erally across a rotating OPC (Organic Photo Conductive) drum that has been positively charged. Wherever the OPC drum is
exposed by laser beam, the image is written and toner is transferred.

To generate a image, the OPC drum suitably rotate to the image length. During each successive pass, the laser exposes the
portions of OPC drum that correspond to component of the image. Toner is attracted to the laser-exposed portions of the OPC
drum.
The paper advances to the fuser, where heat and pressure permanently bond the toner to the paper. From the fuser, the paper
is driven to the output tray.
