17、takes place and recovery time tends to be reduced, thistest method stipulates that the machine shall stay in a readymode for 10 minutes after the end of a job such as copying upuntil it starts passing to the energy-saver mode. The recoverytime from the energy-saver mode to the ready mode shall be se

This testmethod provides energy calculations on the assumption that thepassing time is 10 minutes. If setting of the time shorter than 10minutes is accepted by users in the future,

Nor-mally, this sleep stand-by mode stays for a whole day ofSaturday and Sunday weekends other than standard work days.As for standard work days, the machine stays in this mode atnight as a night stand-by condition.

Summary of Test Method4.1 The standard energy consumption rating is determined(using a watt-hour meter) for a MFD while the machine is in asimulated

30、customer installation performing copying represent-ing a typical days jobs for one eighth (1 h) of the day. Thetypical days jobs (the number of jobs, originals, and copies peroriginal) are based on the standard monthly volume assumedaccording to its copy speed. In this test method, there is nodiffer

31、ence in assumed nominal monthly volumes betweenmonochrome MFDs and color ones. In other words, since acolor MFD naturally has two copying speeds (speeds in colorand monochrome modes), this test method gives the colorMFD the nominal standard monthly volume of a monochromeMFD of which speed equals the

32、 color MFDs maximum speed(normally, in monochrome mode).4.1.1 However, since the job conditions depend on whetheror not a MFD has a color mode, separate job tables have beenprovided for color MFDs and monochrome MFDs.4.1.2 Moreover, note should be taken that two types of jobtables have been provided

33、 for color MFDs according to thestructure (1 drum: serial type, and 4 drum: parallel type).(Refer to the Job Tables in Annex A1.)4.2 The energy consumption may be calculated based on thefollowing assumptions, that the MFD will typically:4.2.1 Be connected to a live power line for thirty 24 h days(72

34、0 h) per month.4.2.2 Be in the operating condition each of 22 work days permonth and be in an operating condition for an average of 9 heach of the 22 days.4.2.3 As a result of items 4.2.2 and 3.1.23, come out of thesleep stand-by mode to enter the wake-up mode each of 22work days, since the MFD norm

35、ally has the sleep stand-bymode where the machine automatically enters after a period oftime of non-use or no job scheduled.4.2.4 As a result of Discussion in item 3.1.9.1, not enter theenergy-saver mode during a copy cycle, if the number ofnominal jobs per hour (18 of a days copying cycle) is 6 orm

36、ore in the job table and this leads to job interval of 10 minutesor less; and as a result of 3.1.13, be in the energy-saver modeduring the 1-h lunch break each of 22 work days. To facilitatethe tests, the upper limit of the number of jobs shall be 6.F24950524.2.4.1 DiscussionIn actual use, the highe

37、r the monthlycopying volume is, the larger the number of jobs is. Besides, itis less likely for the machine to go into the energy-saver mode.Considering these, the numbers of jobs are provided accordingto the nominal monthly volume in the job table and themachine behavior as follows:(1) The nominal

38、monthly volume of 35 000 or less leads tothe number of jobs of 5 or less per hour (18 day) and themachine enters the energy-saver mode during the copyingcycle; and(2) The nominal monthly volume of 42 000 or more leadsto the number of jobs of 6 per hour (18 day) and the machinedoes not enter the ener

39、gy-saver mode during the copying cycle.4.2.5 Perform a typical days copying jobs each of the 22work days each month.4.3 The rating of energy consumption per hour in a typicalmonth (kWh/h) is determined using calculations based on thetest data.5. Significance and Use5.1 This test method provides a pr

40、ocedure for measuring theenergy consumption of the product and optional devices invarious operating modes. It is intended to permit rating theenergy requirements of products by a method that will permitaccurate energy efficiency comparisons of each product withall other similar products.6. Apparatus

Sampling (Equipment Under Test: EUT)7.1 The energy rating should be that for a device represen-tative of the commercially available equipment. Any modifi-cation of the pr

43、oduct or additional configurations that signifi-cantly alter energy consumption will require re-ratings oradditional ratings.7.2 Those MFDs configured with automatic duplex optionshould be rated twice for each job, once at 100 % single-sidedcopy and once at 100 % of two-sided copies (making two-side

44、dcopies from single-sided originals, each side counted as onecopy).7.3 The MFD(s) to be evaluated should be set to within themanufacturers operating specifications.8. Preparation of Apparatus8.1 Test Conditions:8.1.1 The room ambient shall be within a range of 23 63C; 50 6 10 % relative humidity in

45、compliance with ISO 554.8.1.2 The working voltage shall be machine-rated voltage 62 %. Stabilized power supply shall be used.8.1.3 The machine shall be at least 500 mm from any wallor obstacle.8.1.4 All supplies used shall be those specified by the MFDmanufacturer and preconditioned for a minimum of

46、 12 h in theroom ambient environment (see 8.1.1) prior to evaluating theMFD energy rating.8.1.5 The power supply voltage shall be supplied as a truesine wave with no more than 3 % harmonic distortion.8.1.6 The power frequency must be rated frequency 6 0.1Hz.8.1.7 The manufacturer will define the con

47、figuration (in-cluding optional devices) of the machine to be tested, thenominal monthly volume at which it will be rated (see JobTables), and both the first copy speed and multi copy speed.8.1.8 The test should be discontinued if an unusually highnumber of machine problems occur. Excess machine sto

48、ppagesmay distort the overall energy rating. A reasonable number ofpaper jams that can be readily cleared by the operator shouldnot be considered reason to discontinue the test.9. Procedure9.1 Steps 9.1.1-9.1.10 of this procedure should be com-pleted once for each test machine. The data from 9.1.5 w

49、illonly apply to one configuration and, if the machine hasconfiguration variations, the rating must be repeated for eachconfiguration for which the machine is being rated. Prior to thestart of this test, the machine should be plugged in to a livepower line but turned off and stabilized at specified roomambient conditions (indoors) for at least 12 h. An appropriatewatt-hour meter should be in line with the machine, ready togive an accurate indication of machine energy. This test shouldbe run at the machine setting that, in the op
