Hi Gerson,

Some scanner drivers want the scanner to be connected, otherwise an error will occur saying a scanner is not found. Some other drivers I have seen actually allow transferring images from the hard disk, without having the scanner at all. Also, SCSI scanners may need to be on before the computer is started.

Best regards,

Michel
