Scanning by the CCD unit
The CCD unit includes the charge coupled device (CCD) sensor. The cold cathode fluorescent
lamp lights the document, and the reflection from the scanned image data is transferred to the lens
by the mirror. The lens reduces the scanned data so that the image is generated on the CCD.
Function of the machine cover open sensor
The machine cover open sensor detects whether the machine cover is opened or not. Even if the
document is set into the ADF, the machine starts scanning the document glass ignoring the ADF.
Function of the scanner lock lever
The scanner lock lever fixes the CCD unit in position to prevent the CCD unit from moving and
damaging during transportation.
Function of the paper feed solenoid
The paper feed solenoid releases the pick-up roller and separation roller from the drive gear while
duplex scanning and engages them with the drive gear when the document is drawn in order to
prevent that the next document is drawn into the ADF while duplex printing.
Function of the switch back solenoid
The switch back solenoid switches the planet gear of the switch back roller.
