CHAPTER 12: FB ORIGINAL SCANNING SECTION (300 dpi)

3. Stage-Glass Original Detection Mechanism

The FB original detection sensor checks whether an original has been placed on the stage glass. As soon as
the stage cover is closed halfway, blocking the light path to the stage-cover sensor, the FB original detection
sensor checks whether there is an original on the stage glass. If the flatbed original detection sensor is
receiving light (original present), the indication on the operation panel changes to "Master Making" and the
shading-compensation is performed. The image scanner carriage is then moved to the scanning standby
position with the image scanner lamp turned on. If the Start key is pressed within 60 seconds, the scanning
operation starts.
If the Start key is not pressed within 60 seconds, the image scanner lamp turns off and the lamp carriage
returns back to the home position.

4. FB Scanning Mechanism

When the Start key is pressed, the FB read pulse motor activates to move the image scanner carriage in the
scanning direction. After the top 4 mm of the original is skipped, the read signal turns ON and the original
scanning operation starts.
Once the scanning is made for a specific given distance, the image scanner lamp turns off to end the
scanning operation.
If the Book mode scanning is selected, the read signal is turned off for the length of 20mm in the center of the
paper size set on the paper feed tray.
The image scanner carriage returns back to the home position after the scanning operation is finished.
