Scan Settings491JBIG TransmissionIf you use JBIG (Joint Bi-level Image experts Group) compression, you can sendoriginals scanned using [Photo] faster than with other compression methods.Important❒ This function is not available with Internet Fax function.❒ This function requires that the other party's fax machine has both the JBIGfunction and ECM function (G3 communication only).ResolutionThis section explains how to set the resolution of the original.Images and text are scanned into the machine by converting them to a sequenceof dots. The density of the dots determines the quality of the image and how longit 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 quick-ly. Select the setting that matches your needs based upon this trade off betweenspeed and image clarity.❖ Standard (8 x 3.85 lines/mm, 200 x 100 dpi)Select for originals containing normal size characters.❖ Detail (8 x 7.7 lines/mm, 200 x 200 dpi)Select for originals containing small characters or when you require greaterclarity. This resolution is twice as fine as Standard.❖ Super Fine (optional expansion memory required: 16 x 15.4 lines/mm, 400 x 400 dpi)Select for originals with very fine details or when you require the best possi-ble image clarity. This resolution is eight times finer than Standard.
