How to Mark Character Strings
To set keywords for PDF files, mark a character string to be set as a keyword with a water-based
highlight pen so that the character string is completely covered. When you perform a scan, the
marked character strings are recognized and set as keywords for the PDF file.

Minimum: 3 mm [0.12 in.] (short side) × 10 mm [0.39 in.] (long side)
Maximum: 20 mm [0.79 in.] (short side) × 150 mm [5.91 in.] (long side)
