During a scan, the scanner light turns on
and moves across the bed. The charge-
couple device (CCD) in the scanner records
a digital image of the light reflected from
the original you placed on the scanner bed.
The recorded image is made up of 600
pixels per inch (ppi) and each pixel can have
a depth of up to 36 bits.
The resulting image can potentially have
millions of colors.
An image is saved for use in another
program when you drag-and-drop it, save it
as a file and insert the file, or copy it, then
paste it into an open document.
