■ Reference Position for Reading/Printing
The reference position for reading/printing from the copyboard or ADF is explained below.
● Reference Position for Reading
Upper left alignment is applied when the original is read from the copyboard, and center alignment is applied when the original
is read from the ADF.
In the case where only a part of the document is read due to the scaling setting, the read area and the output result differ between
copyboard reading and ADF reading.

Document Feeder System
■ Overview
Pickup/Feed/Delivery Operation
The Auto Document Feeder (ADF) mounted onto this host machine is dedicated to stream-reading.
1 Motor (ADF Motor: M721) is engaged in Pickup/Feeding/Delivery.
At the start of Copy/Fax/Scan, the ADF Motor (M721) is driven by the drive command from the Main Controller PCB to Pickup/
Feed the originals set face up on the original tray one by one in order from the top. The original is scanned by the contact sensor
when moving through the copyboard glass, and then delivered face down to the original Delivery Assembly.
