CanoScan 8800F Technical Reference

1. New Features

(1) CCD scanner with white LED, no need to warm up
High brightness white LED is used as light source for reflective documents and films.
To scan high quality images, technology to convert point light source of LED to line light source with uniform
intensity is essential. It is realized by applying our unique technology for optical guiding device development
acquired by CIS unit development of LiDE series.
Warming up required for traditional fluorescent lamp (approximately 30 seconds at normal temperatures) is no
longer needed. The first scanning starts immediately.
Turning on lamp after scanning is not required. It also serves the energy-conservation.
(2) Faster scanning speed at low resolution
The scanning speed at 300/600dpi, which is often used to scan reflective documents, becomes faster by improving
the data reading method from CCD.
Color 300dpi : 1.0msec/line (8600F: 3.6msec/line)
Color 600dpi : 1.7msec/line (8600F: 3.6msec/line)
(3) Reduced body size
Newly designed carriage (ST lens is used) and white LED used as light source of FAU allow to make the body
approximately 17% thinner than that of 8600F.
