4. e-Filing-specific Adjustments
4.1 To Clearly Store a B/W Image in the Auto Color Mode
Explanation
When a black-and-white original containing black-and-white photo images is scanned in the Auto Color
mode and stored in the e-Filing box (Scan to Box), it is stored with binary data, with reference to a
threshold value. This may make a dark area blurred and a light area eliminated. Adjust the threshold
value, in order to clearly store the black-and-white original in the Auto Color mode.
• This adjustment will have an effect on the image stored using Scan to File and Scan to E-mail.
