Bits Per Pixel
Bell & Howell scanners scan at 1 bit/pixel for black and white. Current
scanner/controller models do not support gray scale or color scanning.
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)
B5 (port and land)
B4 (port)
“port” is short for portrait mode, which orients the paper with the narrower side
on top. Portrait is the default setting.
“land” is short for landscape mode, which orients the paper with the wider side
on top.
