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
1200 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.
