2. Outline of operations
A. Paper path and imaging
Paper is fed, transported, and discharged through the path indicated with the arrow in the figure below.
1)Paper feed (Paper on the paper tray is fed to the transfer section by the paper feed roller.)
2)Image transfer (The toner image on the photoconductor is trans- ferred onto the paper by the transfer roller.)
3)Fusing (The toner image on the paper is fused by the heat roller and the pressure roller.)
4)Paper exit (The paper is discharged to the paper exit tray by the paper exit roller.)

B. Image process and data flow
(1) Copy mode
C1) Images scanned by the image sensor (CCD element) is con- verted into electrical signals (analog signals) and outputted to the MCU PWB. (CCD unit)
C2) Image data outputted from the scanner (reading) section are converted into digital signals.
C3) Image process (area separation, filter process, gamma correc- tion, resolution conversion, zooming) is performed by the ASIC and the line memory (SRAM). The dot image data, the resolu- tion of which is converted from 400dpi to 600dpi, are sent to the data select section. (Image data (LD))
C4) The data are passed through the data select section to the scanner (writing) section. (Image data (V DATA))
In the multi copy mode, image data of one sheet are stored in the DRAM. (Sharp version only)
