Performance—High-Performance Interfaces
In general, Epson scanners targeted to home and small office users have a USB interface for maximum ease
of use. Epson scanners targeted to corporate and graphic arts uses have USB and/or SCSI-2 interfaces for
maximum performance. An optional interface for some scanners is the IEEE-1394 (FireWire
The key differences between the scanner interfaces are:

Performance
* Hot plugging allows you to attach or detach the cable without powering off/on the scanner or computer.
Most Epson scanners that include a USB port offer the newer USB 2.0 (Hi-Speed USB).
Hi-Speed USB is backward compatible with USB 1.1, so if you have an older computer with a USB
port, it will work with a new Epson scanner.
You will see only the highest speeds on your scanner if you have a Hi-Speed USB port on both your
computer and your scanner.
Performance—Batch Scanning
Epson scanning software supports batch
scanning:
Without batch scanning, you must scan
each image separately.
With batch scanning you can define
customized settings for each framed
original, then capture each one as a
separate file—all with one scan.
Flexibility—Intelligent Negative Scanning
With a transparency unit attached, Epson scanners can
scan color negatives (such as 35mm negative strips) and
convert them directly to positive images.
Some other scanners can only scan positive
transparent media, such as color transparencies
and slides.
