Epson's GT-4000 flatbed scanner helps you easily transfer
monochrome and color pictures and text from paper to your
computer, where you can then further process the images.
 
You can scan items in black-and-white mode, which offers up to
256 gray shades, in about 50 seconds. The scanned area is the
size of an A4 page, and you get 16 resolution steps between 50
and 400 dpi (dots per inch).
 
For scanning color images, the GT-4000 offers a resolution of
200 dpi and two scanning modes. When you are transferring images
directly into your computer without manipulation, page sequence
mode gives you red, green, and blue colors, which it scans in
separately in sequence. If you want to manipulate colors, you use
line sequence mode, which scans the document, line by line, in
one run for all three colors. In this mode, the GT-4000 can
correct colors, and it lets you adapt your color output to match
different printer technologies (e.g., high-density 24-pin
printers, low-density 9-pin dot-matrix printers, and
high-contrast printers).
 
A zoom function lets you enlarge and reduce images between 50
percent and 200 percent in 1 percent steps. You can also adjust
the brightness of the reproduction in seven steps.
 
The GT-4000 has a bidirectional parallel interface and an
RS-232C serial interface. To use the parallel interface, you
install a bidirectional interface card into your computer; a
general-purpose interface bus card is available for the Mac. You
can also connect the scanner directly to Epson 24-pin color
printers or Hewlett-Packard PaintJet printers without a personal
computer. In this configuration, the scanner and printer simulate
a color copier.
 
The GT-4000's dimensions are 125 by 310 by 410 mm, and it weighs
10 kilograms.
 
Price: 4000 deutsche marks.
