Image Quality

The following section includes both objective and subjective criteria, which is intended to provide a comparative evaluation of the features and characteristics of the Xerox DocuMate 4799. The features and characteristics of this scanner, which serve as the test criteria, were logically split into two groups: formalizable (e.g. performance), which can be expressed numerically and non-formalizable(e.g. image quality), which represent general impressions.

Important Note

The Xerox DocuMate range of scanners deliver high-quality black and white and office-quality color scanned documents that may not be suitable for all scanning applications and/or customer environments. As such, Customers should carefully evaluate the capabilities and image quality characteristics of the specific Xerox DocuMate scanner they are considering to ensure the scanner is suitable for their environment and Xerox printing system(s). The guidelines outlined herein are provided for informational use only and are not intended to be comprehensive of all factors that should be considered.

Customers who are considering the Xerox DocuMate range of scanners as a replacement for an existing FreeFlow Scanner 665 should not expect to achieve the same levels of image quality and productivity for most scanning applications. However, the Xerox DocuMate scanners are still among the best quality scanners supported for use with FreeFlow Makeready on the market today.

For the purpose of the evaluation, the tests were performed using the Xerox DocuMate 4799 and the Reference Scanner using a set of first generation copies of original test patterns/ images scanned directly to a PC running FreeFlow Makeready. The obtained scans were captured independent of applying image enhancement software, which might otherwise improve or enhance the appearance of the test patterns/images.

Note:

The following performance and image quality evaluation focuses on the Xerox DocuMate 4799 only. Customers interested in the Xerox DocuMate 4790 (or DocuMate 4700) should evaluate the features and characteristics of this scanner to determine if it is a suitable solution for their environment

Performance

The Xerox DocuMate 4799 (and DocuMate 4790), as well as the Reference Scanner, are equipped with Duplex Automatic Document Feeders (ADF), allowing them to scan multi-page, duplex (two-sided documents). The Xerox DocuMate 4799 achieves optimal throughput by scanning both sides of a document simultaneously through the use of dual-image sensors versus the Reference Scanner, which scans each side of a document independently using a single image sensor. The Reference Scanner also incorporates a stationary glass surface (flatbed) for scanning delicate or oversized (up to 12"x18") documents that cannot be accommodated via the ADF.
