Scanner Technical Brief—Page 8 6/07

Performance—Batch Scanning

Epson scanning software supports batch

scanning:

 Without batch scanning, you must scan

each image separately.

 With batch scanning you can deﬁ ne

customized settings for each framed

original, then capture each one as a

separate ﬁ le—all with one scan.

Place originals on

the scanning bed

Select and deﬁ ne frames in

the scanner driver, and scan!

Performance—High-Performance Interfaces

In general, Epson scanners targeted to home and small ofﬁ ce 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

) interface.

The key differences between the scanner interfaces are:

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.

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.
