Theory of Operation
Scanner Assembly
The scanning section consists of a Scanner Assembly that reads a single-
sheet document placed on the document glass, and an Automatic Document
Feeder (ADF) that conveys the pages of a multiple-sheet document.
The optical image reflected from the document reaches the Charged Coupled
Device (CCD) image sensor via the light path.
Scanning on Document Glass
The Scanner Assembly travels to read the document. The following
components are installed on the Scanner Assembly:
■ Exposure Lamp that illuminates light onto the document,
■ CCD Image Sensor that reads light reflected from the document, and
■ Lenses and mirrors comprising the light path for the optical image.
