The Perfection™ 636U is a USB-ready, professional-quality scanner offering superior scans in an extremely easy-to-use package. This revolutionary scanner lives up to its name. For home, school, or home office, it’s the perfect choice. 

In fact, the Perfection 636U’s advanced internal imaging system delivers maximum hardware resolution of 600 x 2400 dpi with Epson’s Micro Step Drive™ technology. With Epson’s ColorTrue® Imaging System, each 36-bit scan recognizes more than 68 billion colors for accurate color reproduction. When scanning documents for written text, the Perfection 636U uses advanced Text Enhancement Technology to eliminate background colors from text. For images or text the end result is the same: perfect scans every time. 

Plug the USB connector into your iMac™, G3, or Windows® 98 computer and add color images to schoolwork, personalize greeting cards and calendars, or send snapshots via e-mail. At work or school, use the Perfection 636U to strengthen newsletters and reports, customize web sites, and produce colorful flyers and proposals. 

The Perfection 636U includes powerful, intuitive scanning software. Adobe® PhotoDeluxe™ makes it easy to retouch photos and add special effects. NewSoft® Presto!™ PageManager document management software offers one button scanning. The features of NewSoft® Presto!™ PageManager OCR (Optical Character Recognition) software bring out sharp, distinct detail when scanning text documents. And Broderbund® The PrintShop™ PressWriter™ features easy-to-use document templates, so creating artwork is a snap! 

For simply perfect scans time after time, the Perfection 636U is a perfectly simple choice.
