National bodies that are members
13、of ISO or IEC participate 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 organiz
14、ations, governmental and 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 D
15、irectives, Part 2. The main 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
16、 the national bodies casting 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 Joint Technical Committee
17、ISO/IEC JTC 1, Information technology, Subcommittee SC 28, Office equipment. This second edition cancels and replaces the first edition (ISO/IEC 24735:2009), which has been technically revised. It also incorporates the Technical Corrigendum ISO/IEC 24735:2009/Cor.1:2009. BS ISO/IEC 24735:2012 ISO/IE
18、C 24735:2012(E) ISO/IEC 2012 All rights reserved vIntroduction Many digital copying devices produce copied pages at a different rate than their nominal speed when running with different modes (simplex, duplex, copying quality modes), different substrate weight and collating and/or finishing options.
19、 The degree to which a reduction in productivity is experienced depends significantly on other parameters of the job stream. The most dominant of the parameters of the job stream are: the number of original pages in a set to be printed, whether ouput pages are single-sided or double-sided, image qua
20、lity modes selected, B&W and colour reproduction job stream, number of print sets to be produced, substrate size used, run length and finishing options. The existing International Standard (ISO/IEC 14545) only addresses the productivity issues for light-lens B&W copying device/duplicators and does n
21、ot take into account these important machine and job related factors for digital copying devices.

22、ductivity 1 Scope This International Standard specifies a method for measuring the “productivity” of digital copying devices and multifunctional devices with various copying modes. It is applicable to digital copying devices and multifunctional devices equipped with automatic document feeder and col
23、lating function. This International Standard is intended to be used for black and white (B&W) as well as colour digital copying devices and multifunctional devices of any underlying marking technology. It allows comparison of the throughput copying rates for a machine operated in various available o
24、perating modes (simplex, duplex, size of substrates, 2-up, etc) and various available digital image processing configurations. This International Standard includes test files, test setup procedures, test procedures, and reporting requirements for digital copying productivity measurements. This Inter
25、national Standard is not intended to be used for devices which are not able to copy on a media size of A4/8.5“x11“, devices that do not have an automatic document feeder (ADF), or devices which are not able to collate multiple copies of original prints from a test set. This International Standard is
26、 not intended to replace manufacturers rated speeds. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includin
27、g any amendments) applies.

28、 and definitions apply. 3.1 duplex copying use of a copying device to make a number of copies with the copying being done on both sides of the sheet NOTE An equivalent term is “two-sided copying” and referred to as 1:2 mode or 2:2 mode. 3.2 effective throughput EFTP average speed at which a device p
29、roduces pages measured from the initiation of the job through the complete exit of the last page of the last test set BS ISO/IEC 24735:2012 ISO/IEC 24735:2012(E) 2 ISO/IEC 2012 All rights reservedNOTE EFTP is expressed in images per minute (ipm). EFTP can be affected by the digital processing time o
30、f the test set as well as the run time of the test set. 3.3 estimated saturated throughput ESAT rate at which a device produces pages measured from the complete exit of the last page of the first test set through the complete exit of the last page of the last test set NOTE ESAT is expressed in image
31、s per minute (ipm). 3.4 feature performance test optional test used to evaluate productivity changes with various copying and finishing features enabled by providing FSOT and ESAT NOTE The feature performance test suite is run with default copying system settings to establish a base line, and then w
32、ith the selected feature (e.g. stapling) ON, for comparison. 3.5 first set out time FSOT number of seconds between the initiation of the job to the complete exit of the last page of the first test set NOTE There is a different definition called “FCOT“ (first copy out time). “FCOT” and “continuous co
33、pying speed” for EP (electrophotographic) copying machines are defined 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 a

40、ment 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% to 70% NOTE The temperature and hu
41、midity 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 The measurement should be made under no-loa
42、d 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. The machine and all of its necessary suppli
43、es shall be acclimated in the test environment prior to conducting the test(s) at least 8 hours. 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 for the copying device. I
44、t 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. For copying devices that
45、 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. Examples include, but are not l
46、imited 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 selected manually. This must be noted in the full detailed report (Annex B).
