Designation:F 1706 96(Reapproved 2008)e1Standard Practice forDetermining Energy Consumption of Nonimpact PersonalComputer Printers1This standard is issued under the fixed designation F 1706;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon(e)indicates an editorial change since the last revision or reapproval.e1NOTEKeywords were added editorially in January 2008.1.Scope1.1 This practice covers a procedure by which nonimpactpersonal computer printers,accessories,and similar officeimaging devices can be tested for energy consumption.1.2 This standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.Referenced Documents2.1 ASTM Standards:2F 335 Terminology Relating to Electrostatic ImagingF 757 Test Method for Determining Energy Consumption ofCopier and Copier-Duplicating Equipment3F 909 Terminology Relating to Printers2.2ANSI Standard:C 12.10Electromechanical Watthour Meters43.Terminology3.1 For definitions of terms used in this practice,seeTerminologies F 335 and F 909 and Test Method F 757.3.2 cycle outthe condition which exists when the machinehas finished printing a page and has returned to a stand-bymode.3.3 energy-saverthe condition that exists when the ma-chine is not printing,has previously reached operating condi-tions,but is consuming less power than when the machine is inthe stand-by mode.3.4 idle timethe amount of time that the machine is notprinting when testing printing energy.3.5 jobprinting pages without interruption or delay be-tween pages.3.6 machine energythe energy consumed by a printer thatis plugged in 24 h/day and turned on 10.5 h(see Note 1),butis not printing pages.NOTE1Some users may want to adjust this time if they do not turn offtheir printers.Therefore,the test should be performed for the plug-in andwarm-up modes,but wont be included in the calculations.If the userwants to include these modes in the calculations,the tester shouldrecalculate the numbers used in Section 10.3.7 machine speed,first pagethe amount of time themachine takes to produce the first page of a job.3.8 machine speed,subsequent pagesthe amount of timethe machine takes to produce multiple pages after the first pageof a job.3.9 printingthe machine condition that exists from thebeginning to the end of the cycle that produces a page or pages.3.10 printing energythe energy consumed during a des-ignated printing mode exclusive of stand-by and plug-inenergy.3.11 printing timethe amount of time that the nominaljobs are run when testing printing energy.3.12 standard pages per daythe number of standard pagesproduced on a single machine during a standard printing day.3.13 stand-bythe condition that exists when the machineis not printing,has reached operating conditions,but has notyet entered into an energy-saver mode.3.14 warm-upthe condition that exists when the machineis turned on from a plug-in mode and prior to printing pages.1This practice is under the jurisdiction of ASTM Committee F05 on BusinessImaging Products and is the direct responsibility of Subcommittee F05.04 onElectrostatic Imaging Products.Current edition approved Jan.1,2008.Published January 2008.Originallyapproved in 1996.Last previous edition approved in 2002 as F 1706 96(2002).2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3Withdrawn.4Available from American National Standards Institute(ANSI),25 W.43rd St.,4th Floor,New York,NY 10036,http:/www.ansi.org.1Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959,United States.4.Summary of Test Method4.1 The standard energy consumption rating 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 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)once foreach of 20 work days each month.4.1.4 Be left on 24 h/day for 2 days of each standard workmonth.4.1.5 As a result of items 4.1.2 and 4.1.3,be left on for anaverage of 10.5 h each of the 22 days.4.1.6 Be in an energy-saver mode some amount of timedepending on the nominal volume and u
