Major Components

Followings are the major components for Document Exposure System.
• The Contact Sensor to scan document
The Reader Motor (M701), the Drive Pulley, the Drive Belt, to shift the Contact Sensor
•
In image scanning control, the Contact Sensor is shifted by rotating the Reader Motor based
on the drive signal from the DCNT PCB and scan the original on the Copyboard Glass.
When ADF is in use, image is scanned by feeding the originals by ADF instead of shifting the
Contact Sensor.
