Summary of Test Method4.1 The standard energy consumption rati

12、ng is determinedfor a printer while the machine is in a simulated customerinstallation performing one eighth of a typical days printingjobs (using a watt-hour meter). The typical days jobs (size andnumber of pages) are based on a standard volume (see Table 1).The simulated customer installation can

13、be calculated withactual usage data, or can be based on the following assump-tions, that the printer will typically:4.1.1 Be plugged in to a live power line for thirty 24-h days(720 h)/month.4.1.2 Be turned on or off, or both, each of 22 workdays/month.4.1.3 Go through a warm-up cycle (if required)

This does notapply to machines with features that allow for continuous operationwithout cycling out.8.1.8 The test should be discontinued if an unusually highnumber of machine problems occur. Excess machine stoppagesmay distort the overall energy rating. A reasonable number ofpaper misfee

33、ds (for example, 1 misfeed per 1000 pages) thatcan readily be cleared by the operator should not be consideredreason to discontinue the test.9. Procedure9.1 Steps 9.1.1-9.1.4 of this procedure should be completedonce for each machine. The data from 9.1.1-9.1.4 applies to allstandard volumes for whic

34、h the machine is being tested. Thedata from 9.1.5 applies only to one configuration, one emula-tion, and one resolution setting, and must be repeated for allother configurations, emulations, and resolution settings forwhich the machine is being tested. Prior to the start of this test,the machine sho

35、uld be plugged in to a live power line butturned off and stabilized at ambient conditions for at least 12 h.The personal computer or Anacom device should be connectedto the printer at least 12 h prior to the test. An appropriatewatt-hour meter should be in line with the machine, ready togive an accu

36、rate indication of machine energy consumptionwithout disruption of the energy source. This test should be runat the printer setting that, in the opinion of the evaluator, is theone yielding the best apparent quality.9.1.1 Printing TimeChoose the appropriate formula inTable 2 that matches the monthly

37、 volume for the machineunder test. Using the manufacturers values for printer speeds,where X is the number of pages per minute for the first page,and Y is the number of pages per minute for subsequent pages,follow appropriate formulas. Record the printing time in Fig. 1.9.1.2 Plug-In EnergyRead and

38、record the watt-hour meterFIG. 1 Sample Data SheetF 1706 96 (2002)3indication and the time (or start the stopwatch or timer). After1 h, read and record the watt-hour meter indication again. Thedifference between the two readings of the watt-hour meter isthe test data for plug-in mode energy use. Rec

39、ord the result inFig. 1, Test Results, Part A. If it is known that the test machineconsumes no energy during the plug-in mode, enter a zero forthe observed data for plug-in energy use and omit this step.9.1.3 Warm-Up Mode Plus Stand-By Mode EnergyWiththe machine in a stabilized plug-in condition, re

40、ad and recordthe watt-hour meter indication and the time (or start thestopwatch or timer). Turn on the machine and allow it to warmup and stabilize in the ready mode. After 1 h, read and recordthe watt-hour indication again. The difference between the tworeadings of the watt-hour meter is the test d

41、ata for warm-upmode plus stand-by mode energy use. Record the result in Fig.1, Test Results, Part B. If it is known that the machine uses noenergy in the warm-up mode (as defined by this procedure)omit this step and proceed to 9.1.4.9.1.4 Stand-by EnergyFor printers with an energy-savermode, disable

42、 the feature. At the conclusion of the previous 1-hmeasurement (9.1.2) leave the machine turned on. After 1 h,record the watt-hour reading. The difference between thewatt-hour reading at the start and finish of the hour is the testdata for the stand-by mode energy. Record the result in Fig. 1,Test R

43、esults, Part C.9.1.5 Energy-Saver EnergyFor printers with an energy-saver mode, enable the feature. If the energy-saver mode isautomatic, let the machine enter the energy-saver mode. Whenit has entered the energy-saver mode, read and record thewatt-hour meter and the time. After 1 h, record the watt

44、hourreading again. The difference between the watt-hour reading atthe start and finish of the hour is the test data for energy-savermode energy. Record the result in Fig. 1, Test Results, Part D.If it is known that the machine does not have an energy-savermode (as defined by this procedure) record

45、the stand-by energy(results from Part C) in Fig. 1, Test Results, Part D.9.1.6 Printing Energy Plus Stand-by EnergyWith themachine in a stand-by mode, read and record the watt-hourindication and the time (or start the stopwatch or timer). Usinga standard original (6.5, 6.6) have the Anacom device pe

46、rformthe standard jobs (Table 1) for the standard volume and modefor which the machine is being tested. Equally space the jobsthroughout the 1 h allocated for this part of the test (Table 1 forjob time interval). The operator should send the original imageso that it has minimal impact on job time an

47、d energy use. Afterthe jobs have been performed and 1 h has elapsed, read andrecord the watt-hour meter indication again. The differencebetween the two readings of the watt-hour meter is the test datafor printing energy use. Record the result in Fig. 1, TestResults, Part E.9.1.7 Energy-Saver Delay T

48、imeFor printers with anenergy-saver mode, if the time to enter the energy-saver modeis adjustable, set the feature to one minute. Print a page. Usingthe timer, record the amount of time it takes the machine toenter an energy-saver mode. If the machine is one which ismanually placed in the energy-sav

49、er mode, activate the featurewhen the machine has cycled out, and then record the time ittakes to reach the energy saver mode. The printer should stayin the energy-saver mode for 1 h. Using the timer, record theamount of time it takes the machine to come out of theenergy-saver mode. Add this time to the amount of time it tookthe printer to go into an energy-saver mode and record theresult in Fig. 1, Test Results, Part F.9.1.8 Recovery Energy Plus Energy-Saver EnergyRepeatthe steps in 9.1.4. When the machine enters the energy-savermode, read and re
