2.2.8.1. Laser Scanning Unit Overview
The Laser Scanning Unit (LSU) consists of one polygon motor and one LD (Laser Diode), and forms a latent image on the
surface of OPC drum. For this process, there is a C-DOE lens, F-Theta Lens, reflective mirror (that changes laser beam
path), the cover glass for protecting the LSU from contamination. Also, LD PBA is located to the front for interface.
The PD sensor located in LD PBA detects the scanning start line and generates the horizontal sync signal (Hsync).
The picture below shows the main components for LSU.
NOTE
The LSU is the optical precision device. Please handle it carefully and do not remove the cover.
