HP Exclusive Scanning Technology to Deliver Advanced Image Quality and Speed

Hewlett-Packard just unveiled an innovation in scanning technology that will enhance image quality and speed, improving consumers’ ability to communicate, collaborate and stay connected through the power of images. Three scanners introduced -- the HP Scanjet 7400C, 7450C and 7490C scanners -- incorporate the technology for the benefit of busy office professionals.
HP’s scanning technology provides leading optical resolution, speed and image quality. This technology allows true 2400 dots-per-inch (dpi) optical resolution for the first time in desktop scanning.

HP scanners with this innovative scanning technology have one 2400-dpi staggered pixel sensor, for high optical resolution, along with one 600-dpi linear pixel sensor, for high speed and excellent image quality when scanning at lower resolutions. By using two separate sensors, HP is able to provide users the higher specifications they demand without sacrificing quality or speed.

The HP technology improves ease-of-use, since the scanner automatically chooses the appropriate sensor for the given scan. For scans that do not require high resolution, the high-speed 600-dpi sensor is used, delivering a four-second preview scan. For scans requiring more exact resolution, such as scanning negatives, the 2400-dpi sensor is used.

HP’s scanning technology also enhances image quality because it works in tandem with improved optics in the HP Scanjet 7400C, 7450C and 7490C scanners. The size and quality of a scanner’s optics are critical to its ability to resolve small detail.

Combining the innovative technology with 48-bit color depth, legal-size platens, PC and Macintosh compatibility and powerful software, the $499 HP Scanjet 7400C, the $699 HP Scanjet 7450C and the $999 HP Scanjet 7490C scanners provide office professionals exactly what they need to get creative jobs done right. The scanners are expected to be available in April 2001.

All three scanners have front-panel buttons for one-touch scanning, e-mailing, faxing, filing and launching the optical character recognition program. In addition, a front-panel liquid crystal display (LCD) allows users to select the number of color or black-and-white copies they need. An options button allows users to customize additional destinations for their scans. The scanners also come with a lighted transparency adapter for scanning 35mm slides, negatives and transparencies up to 5x5 inches.

Additionally, the HP Scanjet 7450C and 7490C scanners come with a 50-page capacity automatic document feeder that scans 15 pages per minute.

The HP Scanjet 7400C, 7450C and 7490C scanners support Microsoft Windows 98, Windows NT 4.0, Windows 2000 Professional and Windows Millennium Edition (Me) and Macintosh OS 8.5 and above. The scanners are expected to support Microsoft Windows 95 by summer 2001.
