Scanning operation

• Scanning an original on the original glass
The rotation of the scan motor (M1) is transmitted to the CIS unit through the timing belt to move the
unit to the home position. The home position is detected when the actuator installed on the CIS case
passes the CIS home position sensor (S1).
When the [START] button is pressed, the CIS unit starts to scan the original.
• Scanning an original on the ADF
The CIS unit (CIS) stops and stays at the shading position during the shading correction, and at the
scanning position during the scanning operation.
