The scanning glass is used to scan fragile documents. On the left of the scanning glass is a scanning strip. It is usedwhen scanning a document through the Automatic Document Feeder (ADF). Scanning strips are also located in the ADF duplex background slotand unit.
How does a scanner work?
Scanners operate by shining light at the object or document being digitized and directing the reflected light (usually through a series of mirrors and lenses) onto a photosensitive element. In most scanners, the sensing medium is an electronic, light-sensing integrated circuit known as a charged coupled device (CCD).

How to turn a flatbed scanner into a camera?
The process involves grinding the glass on the top of the scanning bed using 600 grit silicon carbide powder to turn it, essentially, into a ground glass focusing scree and then mounting it to the back of the camera where you’d normally put the holder that contains the film. It then scans the image projected by the camera onto the ground glass.
