Scanning methods for originals mixed with different sizes (such as A3 & A4 or B4 & B5) differ depending on the settings you make for the scan size and whether you use the exposure glass or the ADF.
If you select [Mixed Original Sizes], the machine detects the length of each original and scans them.
If a regular size is selected, the machine scans originals at the selected size regardless of the actual size of originals. If an original is smaller than the selected size, the machine applies margins to the scan area.
If [Auto Detect] is selected for scanning originals from the exposure glass, the machine detects the size of individual originals and scans accordingly.
When scanning originals of different length at the same time, place them correctly by referring to the chart below. The paper guides cannot be adjusted to small size originals, which may cause slightly tilted scanning.
If you do not select [Mixed Original Sizes] and place originals of different sizes in the ADF, paper jams might occur or parts of the originals might not be scanned.
If only [Auto Detect] is selected for scanning the original with the ADF, the machine scans all originals in the size of the largest original among them.
