Major Components
0006-2872
The image reading/processing system consists of the following major components:
- contact sensor used to read originals
- reader motor, drive pulley, drive belt, carriage, and carriage rail used to move the contact sensor
- The analog processor PCB is used to convert the analog image data colleted by the contact sensor into digital image
data.
The image reading mechanism is controlled based on the drive signals from the image processor PCB, thereby
moving the contact sensor to read the original placed on the copyboard glass.
When the ADF is used, the contact sensor is moved to stream reading position, and the originals are read when they
are moved by the ADF.
