This scanner is equipped ith SCSI I/F in standard. If it is equipped ith
IEEE1394 I/F or special I/F for Copy System on option slot, it can have t o
type I/F.
At this time, to connect and to use above-stated t o type I/F simultaneously is
not guaranteed.
"But, it supports as follo s.
When it provides Net ork solution for Copy System ithout function of
Net ork, it supports to connect and to use simultaneously t o type I/F.
