Creating Off-set Scanning

Modifying the Scan.conf File for Centred ADF Scanning

If you do not want to modify the ADF chute so that it is aligned towards the back of the scanner, you can use the leftOffset option in the Scan.conf file. To calculate the leftOffset option, consider that the paper chute on all supported Fujitsu scanners are 12 inches (2.54 cm) wide . If your paper is 10.5 inches (26.67 cm) wide, the difference between the chute and the paper is 1.5 inches (3.81 cm). Since this difference is distributed on both sides of the paper chute, the offset from either edge is 0.75 inches (1.90 cm). Therefore, the leftOffset option is 0.75 inches (1.90 cm).

The leftOffset option was added to this sample of the Scan.conf file:

host: scan-1
name: Fujitsu10.5
descr: The scanner to use for black & white and greyscale scans.
device: sc1;d5;l0

model: Fujitsu_fi4750C
defaultThreshold: 80
defaultResolution: 200
registrationStrictness: Loose
leftOffset: 0.75

You can add additional entries in the Scan.conf file to support paper of different sizes. For example:

host: scan-1
name: Fujitsu8
descr: The scanner to use for black & white and greyscale scans.
device: sc1;d5;l0
model: Fujitsu_fi4750C
defaultThreshold: 80
defaultResolution: 200
registrationStrictness: Loose
leftOffset: 2
