■ Reference Position for Reading/PrintingThe reference position for reading/printing from the copyboard or ADF is explained below.● Reference Position for ReadingUpper left alignment is applied when the original is read from the copyboard, and center alignment is applied when the originalis 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 betweencopyboard reading and ADF reading.ADF (center alignment) Copyboard(upper left alignment)Set scaling (enlargement)Set scaling(original size < recording paper size)Original Output Original OutputOriginal Output Original Output● Reference Position for PrintingOnly when the original is read from ADF without reduction layout setting (1 on 1), it is printed in center alignment. In other cases,upper left alignment is applied for printing.ADF(center alignment)Copyboard(upper left alignment)1 in 12 in 14 in 1Document Feeder System■ OverviewPickup/Feed/Delivery OperationThe 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.
