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 have high
quality but transmission takes longer. Conversely, low resolution scanning re-
sults 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.
