HS2P Ricoh Scanners
These SCSI-2 (SCAM) production document monochrome scanners scan in 256 shades of gray (8-bit depth) or in B/W. Their optical resolution is 400x400dpi and output resolution is 800 dpi interpolated. They come with both a flatbed and an automatic document feeder (ADF). Models come in various configurations, including duplexing and endorser capabilities. Other optional features include an Image Processing Unit (IPU) and Virtual ReScan (VRS) technology. They can also scan up to A3 (ledger 11x17in).
Currently, Ricoh has discontinued all but the low volume (non-production) IS800C and IS330DC scanners, and a wide format scanner.
