■ Drive Configuration
Description
When copy, fax, or scan is started, the ADF Motor (M11) is driven by a drive command from the Main Controller PCB.
The document which is placed face-up on the Original Tray is picked up and fed one sheet at a time in order from the top.
When the fed original passes over the Platen Glass, the image is read by the Contact Image Sensor (CIS), and then the original
is delivered face-down to the Document Delivery Assembly.

■ Original Detection
Overview
This machine has the following two types of original detection functions.
• Original Detection
• Original Edge Detection
NOTE:
This machine does not have a document size (original width) detection function.
Description
Original Detection
As the actuator is pushed up by placing an original on the Original Tray, the Document Sensor (SR9) is turned ON (light is
transmitted -> light is blocked) so that the presence of an original is detected.
Original Edge Detection
As the actuator is pushed up by the leading edge of the fed original, the Document End Sensor (SR10) is turned ON (light
is blocked -> light is transmitted) so that the leading edge of the original is detected.
In addition, when the trailing edge of the original passes the position of the actuator, the actuator returns to the original
position, which causes the Document End Sensor (SR10) to turn OFF (light is transmitted -> light is blocked) to detect the
trailing edge of the original.
Note that the original length that can be read by this machine is 400 mm and less; if an original longer than that is fed, it is
stopped due to jam. The original length is determined by the time required from when the Document End Sensor (SR10)
detects the original's leading edge to when it detects its trailing edge.
