■ 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.
