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

30、ed image file in the network folder to demonstrate the overall productivity of the device when scanning documents Note 1 to entry: Suffix “ F ” means “Scan to Network Folder Productivity Measurement”. For example, suffix such as “ 30secF ” means a test of “1 set + 30 second” test for “Scan to Networ

36、te 1 to entry: Suffixes such as “ SW ” and “ PC ” are used to show which time measurement is done; by timing device (stopwatch or other device) or by reading time display on the PC dock. For example, “t SW1A ” is the time measured via stopwatch or other device for completion of the first set out and

37、 “t PC1F ” is the time measured via PC clock for completion of the first set file written to the network folder. 3.17 scanning resolution resolution at which the document is scanned 4 Test Parameters and Conditions 4.1 Environment The test environment, including temperature and humidity, shall be wi

38、thin the ranges recommended by the manufacturer for operating the device. If no recommendation is available, the following ranges shall apply. ISO/IEC 2015 All rights reserved 3BS ISO/IEC 17991:2015ISO/IEC 17991:2015(E) Temperature: 18 C to 25 C Relative humidity: 30 % to 70 % NOTE The temperature a

39、nd humidity of the test environment should be recorded in the full detailed report (Annex B). 4.2 Voltage The scanning device shall be connected to a voltage supply within the manufacturer specified operating voltage range for the scanning device under test. NOTE The measurement should be made under

40、 no-load condition prior to each test. 4.3 Scanning Device Setup Place the scanning device on a horizontal surface and set up the scanning device according to the manufacturers recommendations. The scanning device shall be fully enclosed in its normal exterior cover. The machine shall be acclimated

41、in the test environment prior to conducting the test(s) at least 8 h. All images and scanning modes should be at their factory preset configuration for the scanning device. It is assumed that the settings listed in table 1 are common to all scanning devices. These listed settings shall be set to the

42、 manufacturers default or preset condition for the device. If a device has settings not listed in Table 1, they too shall be set to default settings. All settings shall be explicitly stated in either case of default or non-default settings. For scanning devices that have additional scan quality and

43、digital image processing features, those features shall be set to match their normal default condition, and included in the result reporting. Disabling manufacturer default installed features, routines or applications, is not allowed. The following preset values in the test shall be noted in the ful

44、l detailed report (Annex B). Table 1 Preset settings Preset item Preset value Example Mode Scanning resolution default 200 dpi Colour or grey scale/B&W default Colour Duplex/simplex default Simplex Original page size default A4 Paper feed orientation (long/short edge) default Long edge Scan destinat

45、ion default Shared network Storing File Type default PDF (multi) Auto scan quality adjustment default (Factory preset default setting) If the scanning device is setup with internal or external options such as memory as default, then these options shall be noted on the full detailed report format in

46、the configuration options as shown in Annex B, for example “160 GB HDD installed”. Additional tests may be conducted using other, non-default settings for the scanning device. The results of such additional tests shall be documented as having parameters that differ from the factory defaults and show

47、n in comparison to the default system parameter results. Optional paper sizes may be used for the scanning device tests such as A3 and/or 11” 17” size as appropriate for the test mode. When sheets of paper size other than A4/8.5”x11” are used, the sizes shall be indicated in the places of A4/8.5” 11” in the measurement results tables.
