OPERATION
2 Image ReadingIProcessing System
2.1 Outline
The image readingtprocessing system consists of the following major components:
contact sensor used to read originals
reader motor, drive pulley, drive belt, camage, and carriage rail used to move the con-
tact 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. (F04-201-01)
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.
