Scanner Selection
The Scanner menu shows the scanners that are available. If you don’t have any
scanners available, then this fact will be indicated. The last item on this list is
always “show all devices”.
Dots Per Inch
The following choices of dpi are normally available: 200, 240, 300, and 400.
Bits Per Pixel
Three levels of bits per pixel are offered: 1 bit/pixel for black and white and 8
bits/pixel for gray scale.
Brightness
The brightness slider bar varies the brightness of the image, ranging from darkest
on the left to lightest on the right.
Threshold
The threshold slider bar allows you to select the level, below which all pixels are
set to black, and above which all pixels are set to white. Moving the slider bar
setting to the right increases this threshold level.
Auto Document Feeder
If you try to scan with the ADF selected but have no paper inserted in the ADF,
an error message will appear at the bottom of your image display window. The
Preview function is disabled when the scanner is in ADF mode.
Certain pre-defined document sizes are supported by the ADF when it is
installed:
• letter (port and land)
• legal (port)
• 11” x 17”
• A5 (port and land)
• A4 (port and land)
• A3 (port)
