8、ssion)form the specialized system for worldwide standardization. National bodies that are members of ISO or IECparticipate in the development of International Standards through technical committees established by therespective organization to deal with particular fields of technical activity. ISO an
9、d IEC technical committeescollaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, inliaison 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 J
10、TC 1.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 casting a vote.International Standard ISO/IEC 10561 was prepared by Joint Techni
11、cal Committee ISO/IEC JTC 1, Informationtechnology, Subcommittee SC 28, Office equipment.This second edition cancels and replaces the first edition (ISO/IEC 10561:1991), which has been technicallyrevised.Annexes A, B, C and D form an integral part of this International Standard. Annex E is for infor
12、mation only.INTERNATIONAL STANDARD ISO/IEC ISO/IEC 10561:1999(E)1Information technology Office equipment Printing devices Method for measuring throughput Class 1 and Class 2 printers1 ScopeThis International Standard specifies a method for measuring the throughput of class 1 and class 2 printers, as
13、defined in ISO/IEC 11160-1. This International Standard specifies three different test patterns: a standard business letter; a spreadsheet; a graphic pattern.In addition, this International Standard defines a method for a performance test and one for an endurance test.These tests are intended to mea
14、sure only the printer throughput for documents in the same class as the testpatterns and not to evaluate any other printer features such as character shaping, print compressions,network/controller performance, colour, etc. The method is relevant to class 1 and class 2 printer types (e.g. dotmatrix,
15、daisy wheel, ink jet, thermal transfer printers) and to all configurations (e.g. tractor feed, cut sheet feed,80-column and over 132-column print width, etc.). It is not the most suitable for comparing performance of otherclasses of printing devices such as high-speed page-oriented printers or color
16、 printers.This method is intended for use by printer manufacturers and test houses so that a common form of test resultpresentation shall be obtained. It will also enable a user to make a quick and easy comparison of the printingthroughput of different printers.2 Normative referencesThe following st

20、is International Standard.4 Test principles4.1 GeneralFor each test the specified test pattern shall be printed a number of times on the device under test. A test shall beperformed under the conditions specified in clause 5. The initial set-up conditions for the printer shall be asdescribed under ea
21、ch individual test. Once started a test shall be performed without interruption.The performance tests are designed to enable measurement of the printer under typical user application print tasks.The endurance tests are designed to show any effects of extended high duty print tasks on printing throug
22、hput, dueto any limiting factors within the printer (for example, dot density limitations, temperature rises, etc.).For both types of test the throughput unit shall be “printed pages per hour“ and shall be calculated by means of theformula:Number of printed pages x 3600 s/hMeasured time in secondsIS
23、O/IEC 10561:1999(E)ISO/IEC24.2 Performance testIn the performance tests the test pattern shall be transmitted from the host system five times, either as a single,five-page document or as five, single-page documents.The test time measurement shall start from the moment the data arrive at the printer
24、interface. Measurement fromthe moment the “start“ key is depressed on the host computer is permitted, if it can be proved that this does notaffect the test time measurement by more than 1 %.When the test is performed with cut sheet paper the test shall be started with the paper in its normal print m
25、ode. Forprinters pre-loading the paper, the paper path shall be cleared before each test.The measurement of the time required by the test shall end when the fifth sheet has been ejected.For a printer operating with continuous paper the test shall start with the paper loaded to the top of form positi
26、on.The measurement of the time required by the test shall end after execution of the form feed at the end of printingthe fifth page.The performance figures shall be recorded along with a reference to the matrix used.4.3 Endurance testIn the endurance tests the test pattern shall be transmitted from
27、the host system repeatedly for 1 h.The test time measurement shall start from the moment the data arrive at the printer interface. Measurement fromthe moment the “start“ key is depressed on the host computer is permitted, if it can be proved that this does notaffect the test time measurement by more
28、 than 1 %.When the test is performed with cut sheet paper the test shall be started with the paper in its normal print mode. Forprinters pre-loading the paper, the paper path shall be cleared before each test.For a printer operating with continuous paper the test shall start with the paper loaded to
29、 the top of form position.The measurement of the time requested by the test shall end with the completion (ejection) of the first sheet after1 h has elapsed (1 h and n seconds) so that a whole number of pages shall be printed.The 1 h test time shall include any time required to reload paper, change
30、ribbon cassette or replenish ink/tonersupplies. It is assumed that the test is commenced with new consumables, loaded to capacity.The endurance figures shall be recorded along with a reference to the matrix used.5 Test conditions5.1 Test environmentThe test shall be performed in the following enviro
31、nment.Temperature: 18 C to 25 CRelative humidity: 30 % to 70 %The printer, fully enclosed in its normal operating cover set, shall be acclimatized in the test environment in poweredcondition for at least 1 h.5.2 VoltageThe printer shall be connected to a voltage supply which remains within 10 % of t
32、he nominal value of the specifiedoperating voltage for the printer under test.5.3 Data inputData shall be sent to the printer at such a rate that the printer is never waiting for data to arrive and thereforeproducing a misleading (lower) throughput figure.5.4 Test sequenceEach test sequence shall be
33、 completed without stopping.After each test sequence the printer shall be allowed to re-stabilize (cool down) to its normal powered up ambientstate.ISO/IECISO/IEC 10561:1999(E)35.5 Print paperThe paper used shall have the following weight cut sheet: 60 g/m2 to 90 g/m2 fanfold single ply: 60 g/m2 to
34、80 g/m2 fanfold multiply: according to the manufacturers specification.For testing with fanfold multiply paper an original plus two copies shall be used. The manufacturer shall specify thetype of the paper and carbons.A printer configured for continuous paper (tractor, pin wheel or friction feed) sh
35、all preferably be loaded with304,8 mm (12 in) form length paper. If this is not possible any near equivalent length may be used but the testpatterns can then be printed over more than one page. Any “skip over perforation“ feature in the printer shall bedisabled.A printer configured for cut sheet pap
36、er shall be operated in automatic mode, not in manual single sheet feed mode.A4 size paper or near equivalent shall be used. If a size other than A4 is used, the size shall be so recorded in thetest results.The printer shall be tested with single ply paper and also with three-ply paper (original plu
37、s two copies). The multiplytest shall only apply if the printer can handle at least three-ply paper (original plus two copies, with or without carboninterleaves).6 Letter test6.1 GeneralThis test simulates a typical user application of printing a letter.6.2 Test patternsTwo test patterns are defined
38、 in annex B. The first one (pattern A) is the standard letter defined in DIN 32751. Thesecond pattern (pattern B) is a letter in English to be used for printers not printing diacritical signs. The results of thetwo test patterns are not comparable, and the test patterns used shall be declared in the
39、 test results.The printer shall be set up for 0,4 characters per millimetre (10 cpi)1)and 0,24 lines per millimetre (6 lpi)2)operation.If the manufacturer declares more than one print quality mode, test 1 shall be made with the printer set to the lowestquality mode, and tests 2 and 3 with the printe
40、r set to the highest quality mode.6.3 Test 1 - performanceSet the printer to the lowest quality mode.6.4 Test 2 - performanceSet the printer to the highest quality mode.6.5 Test 3 - enduranceSet the printer to the highest quality mode.7 Spreadsheet test7.1 GeneralThis test simulates a typical user a
41、pplication of printing a spreadsheet.If the manufacturer declares more than one print quality mode, the test shall be made with the printer set to thelowest quality mode and for 0,24 lines per mm (6 lpi).7.2 Test patternThe test pattern shall be the 132-column spreadsheet shown in annex C.1)cpi = ch
