The machine goesint

13、o this mode after it completes a copying job and no job isscheduled in a specified time period. Since the InternationalEnergy Star Program has been used widely in the world, thishas caused copiers to have this mode. This standard particu-larly designates this condition as an energy-saver mode inoper

14、ating hours (9 h) of a standard work day.3.1.9.1 DiscussionThe International Energy Star Programstipulates that the machine shall be set to enter an energy-savermode 15 minutes or less after the end of a copying job.However, considering the fact that shorter passing time hasbeen set than before beca

17、 of a copying job up until itstarts passing to the energy-saver mode if no job is scheduled.The recovery time from the energy-saver mode to the readymode shall be set to 30 seconds or less. Energy-saver modedesign to fulfill this recovery time is left to the manufacturersdiscretion. This test method

18、 provides energy calculations onthe assumption that the passing time is 10 minutes. If setting ofthe time shorter than 10 minutes is accepted by users in thefuture, the procedure of this test method will be reviewed.3.1.10 auto-off modethe condition with less energy con-sumption than the energy-save

19、r mode in 3.1.9. The machineenters the energy-saver mode 10 minutes after the end of acopying job if no job is scheduled in the ready mode. Later, themachine enters an auto-off mode, if no additional job isscheduled in a specified time period. Normally, this auto-offmode stays for a whole day of Sat

20、urday and Sunday weekendsother than standard work days. As for standard work days, themachine stays in this mode at night as a night stand-bycondition. It is calculated by subtracting the 9 hours ofoperation from the 24 hours in a day. The machine comes outof this mode when the user manipulates the

21、machine for a jobor switches it on.3.1.11 energy-saver recovery timethe amount of time thatthe machine takes to enter the ready mode after it comes out ofthe energy-saver mode in the 9-h operating condition of astandard work day.3.1.12 energy-saver mode timethe amount of time that themachine is in a

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

29、simulated customer installation performing one eighth (1 h)of a typical days copying jobs. The typical days jobs (thenumber of jobs, originals, and copies per original) are based onthe standard monthly copying volume assumed according to itscopy speed. In this test method, there is no difference ina

30、ssumed nominal monthly copying volumes between mono-chrome copiers and color ones. In other words, since a colorcopier naturally has two copying speeds (speeds in color andmonochrome modes), this test method gives the color copierthe nominal standard monthly copying volume of a mono-chrome copier of

31、 which speed equals the color copiersmaximum speed (normally, in monochrome mode).4.1.1 However, since the job conditions depend on whetheror not a copier has a color mode, separate Job Tables have beenprovided for color copiers and monochrome copiers.4.1.2 Moreover, note should be taken that two ty

32、pes of JobTables have been provided for color copiers 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 copier will typically:4.2.1 Be connected to

33、a live power line for thirty 24 h days(720 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. The operating condition of 9 h includes alunch break of 1 h.4.2.3 As a result of 4.2.2 and 3.1.23, come

34、 out of theauto-off mode to enter the warm-up mode each of 22 workdays, since the copier normally has the auto-off mode wherethe machine automatically enters after a period of time ofnon-use or no job scheduled.4.2.4 As a result of Discussion in 3.1.9.1, do not enter theenergy-saver mode during a co

35、py cycle, if the number ofnominal jobs per hour (18 of a days job cycle) is 6 or more inthe Job Table and this leads to job interval of 10 minutes orless; 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

36、 the number of jobs shall be 6.4.2.4.1 DiscussionIn actual use, the higher 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 accordingF2494052to the nominal mo

37、nthly volume in the Job Table and themachine behavior as follows:(1) The nominal monthly copying volume of 23 000 or lessleads to the number of nominal jobs of 5 or less (18 day) andthe machine enters the energy-saver mode during the copyingcycle; and(2) The nominal monthly copying volume of 28 000

38、ormore leads to the number of nominal jobs of 6 (18 day) and themachine does not enter the energy-saver mode during thecopying 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 usin

39、g calculations based on thetest data.5. Significance and Use5.1 This test method provides a procedure 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 permitaccu

Sampling7.1 The energy rating should be that for a device represen-tative of

42、 the commercially available equipment. Any modifi-cation of the product or additional configurations that signifi-cantly alter energy consumption will require re-ratings oradditional ratings.7.2 Those copiers configured with automatic duplex optionshould be rated twice for each job, once at 100 % si

43、ngle-sidedcopy and once at 100 % of two-sided copies (making two-sidedcopies from single-sided originals, each side counted as onecopy).7.3 The copier(s) to be evaluated should be set to within themanufacturers operating specifications.8. Preparation of Apparatus8.1 Test Conditions:8.1.1 The room am

44、bient shall be within a range of 23 63C; 50 6 10 % relative humidity in 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 th

45、ose specified by the copiermanufacturer and preconditioned for a minimum of 12 h in theroom ambient environment (see 8.1.1) prior to evaluating thecopier 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 freque

46、ncy must be rated frequency 6 0.1Hz.8.1.7 The manufacturer will define the configuration (in-cluding optional devices) of the machine to be tested, thenominal monthly copying volume at which it will be rated (seeJob Tables), and both the first copy speed and multi copyspeed.8.1.8 The test should be

47、discontinued if an unusually highnumber of machine problems occur. Excess machine stoppagesmay 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

48、this procedure should be com-pleted once for each test machine. The data from 9.1.5 willonly 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

49、 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 opinion of theevaluator, is the one yielding an appropriate copy.9.1.1 Copying TimeChoose the appropriate formula fromJob Tables (see Annex A1) that matches the monthly volumefor which the machine is being rated, according to t
