2.9. Scanner System

This section describes the printer scanner system parts and functions.

The scanner is a device to change from the image to the data. To scan the picture, image on the original, it uses the lens and

CCD(Charge Coupled Device). It stores and transfers the converted image to the storage space or transfers the scanned

data to the printer engine for copy.

For scan operation, the scanner uses FR carriage and HR carriage that is moved by the wire. And it scans the original

document on the scan glass or ADF(Auto Document Feeding).

The scanner system consists of 3 modules following below.

FR(Full Rate) carriage: Illuminates the original and reflects the light at a 90 degree angle.

HR(Half Rate) carriage: Transfers the reflected light from the FR carriage to the lens.

Imaging module: Make an image on CCD

HR carriage moves at half distance and half speed of FR carriage. This principle keeps a regular gap between the original

and imaging lens.
