4) Scheduledactivities,e.g.ListExports,Configurations,FirmwareUpgrades,shouldbeplanned
withtheunderstandingthattheywillwaketheprinter.
Inaddition,thedelayofwakingfromAuto‐OffcanresultinWJAtemporarilyreportingCommunication
Errorforthatprinter.
RemoteManagementAppliance(RMA)
RMAisusedinManagedPrintServicedeploymentstogatherusagestatisticsforaccountingusing
SNMP.DisablingSNMPisnotpossibleinsuchdeployments.
WhenRMAisinuse,itisrecommendedthatthestatisticsgatheringbescheduledfornormalworking
hoursratherthanoff‐hours.Thiswillavoidtheunnecessary
wakeup.
Clientworkstations
Inenvironmentsusing“DirectIP”printinginwhich individualclientsconnectdirectlytotheprinter,the
numberofclientsandtheiruseofSNMPcancausetheprintertoawakefromAuto‐Offfrequently.In
suchenvironments,itisrecommendedthateitherSNMPbedisabledattheprinterorthatthe
clientsbe
shutdownforthenon‐businesshours.Shuttingtheclientsdown,ofcourse,hastremendou sbenefitsin
reducingenergyconsumption.
EnergyEfficientEthernet(EEE)Networking(IEEE802.3az‐2010)
Networking,particularlyformodernhighspeednetworks(100mbpsFastEthernetand1000mbps
GigabitEthernet)requiressignificantpower.EEEisanew(2010)standardforEthernetnetworkingthat
dynamicallymanagesthenetworkinghardware,shuttingitdownwhenidleandbringingitbackquickly
whenneeded.Thisdynamicapproachconsiderablyreducesenergyconsumption,
especiallywhen
operatingatFastEthernet(100Mbps)orhigher.
TheM500andM600printersareEEE‐enabledallowingthemtoachieveconsiderableenergysavings
whenconnectedtoanetworkinfrastructurethatissimilarlyEEE‐enabled.Ofcourse,theywillalso
interoperatewithnetworkinginfrastructuresthatdonothavetheenergy
reducingfeaturesofEEE.
NotethattheEEEenergyfeaturesareentirelyindependentofAuto‐On/Auto‐Off;EEEwillreduceenergy
consumptionregardlessoftheEnergySettings.

Auto‐Offwake‐updelay
Thereisasignificantdelay,2‐5seconds,requiredtowakeaprinterfromAuto‐Off.Duringthistime 
networkpacketsmaybereceivedbytheprinterbutwillbelost.
