B. Operational descriptions
The operation panel unit is composed of the LCD unit, the LVDS PWB, the USB I/F PWB, and the KEY PWB. It displays the machine operation.
It is provided with the USB I/F which is used for the firmware update, USB print, and Scan to USB.
In addition, the USB I/F line is provided inside the operation panel to connect with the keyboard and the IC card reader.
A document size is detected by the document size detection PWB (light emitting) and the document size detection PWB (light receiving).
The detection timing of document size is determined according to the document size detection trigger sensor signal.
