Embedded OCR (Searchable PDF)
 When the scan resolution is set below 200dpi, OCR quality may
not be good enough to create a Searchable PDF. As a result,
Searchable PDF cannot be used. Therefore, Searchable PDF
cannot be used when the resolution is set less than 200dpi.
 Actual scanning resolution will become less than 200dpi when
the size of the image is reduced. In this case, users can use
Searchable PDF, though OCR quality deteriorates.
 When there are email size limitations and the scanned file size
exceeds it, the whole file will be automatically divided to multiple
files. In this case, the system ignores the limitation of file
quantities.
 If the receiver PC doesn't support a specific language, the file
name will be corrupted when the file name is set automatically,
 Users cannot use these functions at the same time:
 Searchable PDF + Encryption + PDF/A + Signature
 Searchable PDF + High compression PDF + PDF/A
 Processing time will be depend on the following items. Therefore,
some cases takes a long time to create a Searchable PDF.
 Controller spec / The number of characters / Resolution / Paper
