18、ABS .ISO/IEC 24735:2009(E) iv ISO/IEC 2009 All rights reservedForeword ISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participat

19、e in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and

20、 non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The m

21、ain task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the national bodies cas

22、ting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. ISO/IEC 24735 was prepared by Technical Committee ISO/TC JTC1, Information techn

24、rate than their nominal speed when running with different modes (simplex, duplex, copying quality modes), different substrate weight and collating and/or finishing options. The degree to which a reduction in productivity is experienced depends significantly on other parameters of the job stream. The

25、 most dominant of the parameters of the job stream are: (the number of original pages in a set to be printed, single-sided or double-sided output pages, image quality modes selected, B first copy out time”. This “FCOT” and “continuous copying speed” for EP (electrophotographic) copying machine is de

26、fined in ISO/IEC 21117. For reference, the extension of these definitions also applied for out of scope copying devices is shown in Annex D (informative). 3.6 full detailed report presentation of information including machine setup and measured test results 3.7 full report presentation of results in

27、cluding the FSOT, ESAT and EFTP values in general performance test or the FSOT and ESAT values in feature performance test as well as the calculated averages for each values 3.8 general performance test test used to evaluate productivity by providing FSOT, ESAT and EFTP without using any special fea

28、ture or mode, and includes both the simplex copying mode and the duplex copying modes of 1:2 and 2:2 if available 3.9 LSOT last set out time number of seconds between the initiation of the job to the complete exit of the last page of the last test set 3.10 nominal copying speed copying rate, excludi

29、ng time to first page copied, and measured when producing pages in a continuous copying mode with a single static document using a nominal weight substrate NOTE Nominal copying speed is expressed in copies per minute or images per minute. 3.11 simplex copying use of a copying device when only a sing

30、le side of a sheet is copied on NOTE Other equivalent terms are “one-sided copying” or “simplex to simplex” (referred as 1:1 mode).

33、eters and Conditions 4.1 Environment The test environment, including temperature and humidity, shall be within the ranges recommended by the manufacturer for operating the device. If no recommendation is available, the following ranges shall apply. Temperature: 18 C to 25 C Relative humidity: 30 % t

34、o 70 % NOTE The temperature and humidity ranges of the test environment should be recorded in the full detailed report (Annex B). 4.2 Voltage The copying device shall be connected to a voltage supply within the manufacturer specified operating voltage range for the copying device under test. NOTE Th

35、e measurement should be made under no-load condition prior to each test. 4.3 Copying Device Setup Place the copying device on a horizontal surface and set up the copying device according to the manufacturers recommendations. The copying device shall be fully enclosed in its normal exterior cover. Th

36、e machine and all of its necessary supplies shall be acclimated in the test environment prior to conducting the test(s). All supplies used in the test(s), included copy paper, shall be those specified by the manufacturer. All image and copying modes should be at their factory pre-set configuration f

37、or the copying device. It is assumed that the settings listed in table 1 are common to all copying devices. These listed settings shall be set to the manufacturers default or pre-set condition for the device. If a device has settings not listed in Table 1, they too shall be set to default settings.

38、For copying devices that have additional print quality and digital image processing features, those features must 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. Example

39、s include, but are not limited to the following: automatic cleaning or calibration cycles, and energy save settings. If the system has automatic media detect(automatic paper type selection), it can be disabled, and paper used in the test shall be SANS 24735:2009This s tandard may only be used and pr

Care must be taken to use a paper that conforms to the copying device man

45、ufacturers paper specifications for the default copying device settings. The paper used for the general performance test section 5.4 shall be cut-sheet, A4 and/or 8.5“x11“ size. Optional paper sizes may be used in the feature performance tests such as 8.5“x14“, A3, and/or 11“x17“ size as appropriate

46、 for the test mode. The paper manufacturer, weight, size and paper type/name used in each test shall be noted on the full detailed report. NOTE When you use the papers other than A4/A3, then you should state each paper size in the places of A4 and A3 at the presentation of results. And you should us

47、e the same paper size by each machine when you want to compare the productivity results of one machine with other machines. If the copying device is used in “thick paper mode” for copying, then this optional mode shall be noted on the full detailed report format in corresponding column in Annex B. 4

48、.5 Maintenance Copying device maintenance shall be performed throughout testing per the manufacturers recommendations on an as needed basis. (For example, cleaning routines or consumables replacement). 4.6 Preparation of Test Targets (Test Charts) The copying test file is outlined in Annex C (normat
