For my project in the course "Digitala Projekt" I choose to build
an automatic scanner.
By this I mean a scanner that scans multiple
pages without user intervention.
I choose to do this by using parts
taken from an old inkjet printer and a flatbed scanner.
The system works as follows:
*A Atmel miniature computer controlls the system.
*A linear ccd image sensor captures each line.
*The paper feed mechanism from an inkjet printer advances the pages.
*A PC recieves the captured data and combines all the lines from one page into an image.
Using parts that you know nothing about is not a good idea. This project has required many hours of reverse engineering just to find out how the sensor operates.
