– The default file format is <PDF>.
– If you want to scan multipage documents, scan the documents by the ADF.
– The scanned images will be saved with serial numbers from 0001_0001.

– When scanning multiple page documents, <MEMORY FULL> or <USB MEMORY FULL> may appear in
the LCD and scanning may be canceled. If this happens, press [OK] to return to standby mode. When
<MEMORY FULL> is displayed, print, send, or delete any documents stored in memory. When <USB

– For a USB memory formatted with the FAT16 file system, the maximum number of files that can
be saved in the root directory (the top level of the directory tree in the USB memory) is only 255.
It is recommended that you use a computer to organize the root directory of your USB memory
beforehand by moving existing files to a newly created folder or by deleting unnecessary files. If all
files in the USB memory are unnecessary, formatting the USB memory to FAT32 is also recommended.
– If the destination folder of the scanned images contains many files, the time it takes to save will
increase. It is recommended that you use a computer to organize your destination folder beforehand
by moving existing files to a newly created folder or by deleting unnecessary files.
– If you are using a USB memory that show multiple drives on a computer instead of just one, saving
scanned images to a specific drive is not possible. To find and check where they are saved, use your
computer to open and check each drive or search them by their file names or the date modified.
