Resolution
This section explains how to set the resolution of 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 quick-
ly. Select the setting that matches your needs based upon this trade off between
speed 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 greater
clarity. 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.
