JBIG Transmission

If you use JBIG (Joint Bi-level Image experts Group) compression, you can send originals scanned using
[Photo] faster than with other compression methods.
• This function is not available with a transmission to Internet Fax destination, e-mail destination, and
folder destination.
• This function requires that the other party's fax machine has both the JBIG function and ECM function
(G3 communication only).

Resolution

Specify the resolution according to the size of the text on the original.
Images and text are scanned into the machine by converting them to a sequence of dots. The density of
the dots determines the quality of the image and how long it takes to transmit. Therefore, images scanned
at high resolution (Super Fine) have high quality but transmission takes longer. Conversely, low resolution
(Standard) scanning results in lower quality but the original is sent more quickly. Select the setting that
matches your needs based upon this trade off between speed and image clarity.
Standard (8 × 3.85 lines/mm, 200 × 100 dpi)
Select for originals containing normal size characters.
Detail (8 × 7.7 lines/mm, 200 × 200 dpi)
Select for originals containing small characters or when you require greater clarity. This resolution is
twice as fine as Standard.
Super Fine (optional expansion memory required: 16 × 15.4 lines/mm, 400 × 400 dpi)
Select for originals with very fine details or when you require the best possible image clarity. This
resolution is eight times finer than Standard.
