19、ment methods of copying and printing were published as ISO/IEC 24735 and ISO/IEC 24734. However, ISO/IEC 24735 contains no measurement method for the scanning productivity of multifunctional devices to be used for comparison and procurement of these machines. This International Standard provides a g
20、eneral method for measuring “scanning productivity” of the multifunctional devices. The International Standard also includes a test chart for scanning productivity measurement. It allows the manufacturers and the buyers of digital multifunctional devices to describe the productivity of various digit
21、al scanning devices with respect to representative office usage.

22、fies a method for determining scanning productivity by measuring “scanning speed” and “scan to network folder speed”. It includes test files, test setup procedure, test procedure, and the reporting requirements for the scanning productivity measurements. This International Standard is applicable to
23、black and white (B it can be affected by scan time, digital processing time, maintenance and the run time of the test. Note 3 to entry: A different term (“EFTP; effective throughput” for digital copying machines) is defined in ISO/IEC 24735. Note 4 to entry: As for scEFTP 30secF , measurement parame
24、ters involving the measurement of file transmission to a network folder are dependent on other factors like the computer and network configuration and represent relative values and not absolute values. 3.4 scanning Estimated Saturated Throughput scESAT rate at which a device scans pages measured fro
25、m full ejection of the last page of the first test set from ADF through the full ejection of the of the last page of the scanning sets (using suffix “ A ”) Note 1 to entry: scESAT is expressed in images per minute (ipm). Note 2 to entry: There are suffixes such as “ 1setA ” or “ 30secF ”. Each suffi
26、x is used to classify tests such as “1 set Test” or “1 set + 30 second test” for “ADF Productivity Measurement”(using suffix “ A ”) or “Scan to Network Folder Productivity Measurement”(using suffix “ F ”) test respectively. There is no measurement for “Scan to Network Folder Productivity Measurement
27、” of scESAT, scESAT 30secFdefined, therefore scESAT 1setAand scESAT 1setFare not used as classifications. 3.5 scanning First Set Out Time scFSOT number of seconds between the initiation of the job to full ejection of the last page of the first test set from ADF Note 1 to entry: There are suffixes su
28、ch as “ 1setA ” or “ 30secF ”. Each suffix is used to classify tests such as “1 set Test” or “1 set + 30 second test” for “ADF Productivity Measurement”(using suffix “ A ”) or “Scan to Network Folder Productivity Measurement”(using suffix “ F ”) test respectively. 3.6 full detailed report presentati
