FEB 27--Hewlett-Packard Co. (Palo Alto, CA; www.hp.com) unveiled three scanners implementing an innovative scanning technology. The HP Scanjet 7400C, 7450C, and 7490C scanners provide true 2400 dots-per-inch (dpi) optical resolution.

These scanners use one 2400-dpi staggered pixel sensor for high resolution and one 600-dpi linear pixel sensor for lower resolutions. Using two separate sensors results in higher resolution without sacrificing quality or speed.The scanner automatically chooses the appropriate sensor for a given scan.

All three scanners provide front-panel buttons for one-touch scanning, e-mailing, faxing, filing, and launching an optical-character-recognition program. A liquid-crystal display lets users select the number of color or black-and-white copies needed. Software support includes Windows 95/98/NT4.0/2000 Professional/ME and Macintosh OS 8.5. The 7450C and 7490C scanners come with a 50-page document feeder that allows a scan rate of 15 pages per minute.
