LSU (Laser Scanner Unit)
The LSU unit is controlled by video controller. It scans the video data received from video control-
ler with laser beam by
using the rotation principle of the polygon mirror to create the latent image on the OPC drum. It is
the core part of LBP. The OPC drum rotates as the same speed as the paper feeding speed. It
creates the /HSYNC signal and sends it to the engine when the laser beam of the LSU reaches
the end of the polygon mirror, and the engine detects the /HSYNC signal to arrange the vertical
line of the image on the paper. After detecting the /HSYNC signal, the image data is sent to the
LSU to arrange the its margin on the paper.
The one side of the polygon mirror is one line for scanning.
Print Cartridge
In the print cartridge, the OPC unit and the developer unit are in a body.
The OPC unit has OPC drum and charging roller, and the developer unit has toner, print cartridge,
supply roller, developing roller, and the blade.
