OPE Assembly
1) Configuration
The OPE Panel is consists of the Micom Controller, Matrix part and LCD.
2) Micom controller
Micom has ROM, RAM, built-in I/O Port, displays and LCDs which is controlled by the CPU com-
mands of the Main Controller. It also sends Key recognition data to the Main Control Board.
Print Engine
The mechanical aspect of the print engine consists of the frame, feed element, developer, drive,
toner transfer and fuser. The print engine is controlled directly by the Main PBA which handles all
Image and video data to the LSU and manages the printing. The Main PBA also has mounted pa-
per jam sensors to recieve signals directly.
Scanner
1. Pictorial signal input part:
The output signal of the CIS passes through the Bypass Cap and goes to the ADC at the IP Main.
AFE then accepts each pixel, CDS (Correlated Double Sampling) technique which samples arm-
level twice is used on each pixel by using IP signal.
2. Pictorial image processing part
This read CIS Pixel data in terms of 600dpi Line and process LAT algorithm on text mode, Error
Diffusion Algorithm on Mixed mode, and stores data at the Scan Buffer on PC Scan mode without
algorithm. On every mode, Shading Correction and Gamma Correction are executed ahead then
processing is executed later.
