Performance and Image Quality Expectations Guide 3-133 Performance andImage QualityThe following section includes both objective and subjective criteria, which is intended toprovide a comparative evaluation of the features and characteristics of the Xerox DocuMate4799. The features and characteristics of this scanner, which serve as the test criteria, werelogically split into two groups: formalizable (e.g. performance), which can be expressednumerically and non-formalizable (e.g. image quality), which represent general impressions.Important NoteThe Xerox DocuMate range of scanners deliver high-quality black and white and office-qualitycolor scanned documents that may not be suitable for all scanning applications and/orcustomer environments. As such, Customers should carefully evaluate the capabilities andimage quality characteristics of the specific Xerox DocuMate scanner they are considering toensure the scanner is suitable for their environment and Xerox printing system(s). Theguidelines outlined herein are provided for informational use only and are not intended to becomprehensive of all factors that should be considered.Customers who are considering the Xerox DocuMate range of scanners as a replacement foran existing FreeFlow Scanner 665 should not expect to achieve the same levels of imagequality and productivity for most scanning applications. However, the Xerox DocuMatescanners are still among the best quality scanners supported for use with FreeFlow Makereadyon the market today.For the purpose of the evaluation, the tests were performed using the Xerox DocuMate 4799and 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 werecaptured independent of applying image enhancement software, which might otherwiseimprove or enhance the appearance of the test patterns/images.Note:The following performance and image quality evaluation focuses on the Xerox DocuMate4799 only. Customers interested in the Xerox DocuMate 4790 (or DocuMate 4700) shouldevaluate the features and characteristics of this scanner to determine if it is a suitable solutionfor their environmentPerformanceThe Xerox DocuMate 4799 (and DocuMate 4790), as well as the Reference Scanner, areequipped with Duplex Automatic Document Feeders (ADF), allowing them to scan multi-page,duplex (two-sided documents). The Xerox DocuMate 4799 achieves optimal throughput byscanning both sides of a document simultaneously through the use of dual-image sensorsversus the Reference Scanner, which scans each side of a document independently using asingle image sensor. The Reference Scanner also incorporates a stationary glass surface(flatbed) for scanning delicate or oversized (up to 12"x18") documents that cannot beaccommodated via the ADF.
