4.1 To Clearly Store a B/W Image in the Auto Color Mode
After the adjustment
Before the adjustment
The light image becomes blurred and text
becomes illegible.
Even the light image is not blurred. Text is
clear and legible.
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.
* Please remember that the e-Filing functions are available only on the Windows platform, and not on the
Macintosh or UNIX platform.
* This adjustment will have an effect on the image stored using Scan to File and Scan to E-mail.
