Auto‐Off/Auto‐OnTechnology
TheM551,M601,M602andM603HPEco‐SmartLaserJetprintersfeatureAuto‐Off/Auto‐On
technologythatdramaticallyreducestheirpowerconsumption.Auto‐Off/Auto‐Ondisablesnon‐
essentialbackgroundfunctionstoreducepowerconsumptiontolessthanonewattwhentheprinteris
idle.
TheM500andM600seriesprintersprovide
fourpowermodes:
WhenOFF,theprinterwilldrawlessthanhalfawatt.TheprintercanbeturnedOFFmanually
withthepowerbuttonorautomaticallybythesleeptimer.WhenOFF,theprintercanbe
turnedbackononlywiththepowerbu tton.WhenOFF,thepower
buttonisunlit.
Whenenabled,asleeptimerputstheprinterintoAuto‐Offinwhichitdrawslessthanonewatt.
TheprinterwillawakeautomaticallyfromAuto‐Offforprintingandmaintenancetasksfromthe
network.WheninAuto‐Offthepowerbuttonwillblinkatapproximatelythree
second
intervals.
InSleep,theprinterdrawsapproximatelysixwatts(dependingonspecificmodels andinstalled
features)and,likeAuto‐Off,willreactautomaticallyforprintingandmaintenancetasks.The
controlpanelremainsfullyoperationalaswell.However,fromSleep,theprinterwillreact
morequicklythanfromAuto‐
Off.WheninSleep,thepowerbuttonwillblinkatapproximately
threesecondintervals,indistinguishablyfromAuto‐Off.
TheprintermustbeREADYforprintingandwillconsumepowerrangingfromtwentywatts
whenidle(waitingforjob)toseveralhundredwattswhileactivelyprinting.Theprinterwill
automaticallyfall
intoSleep,Auto‐Off,orOFF,basedonthesleeptimer.Whentheprinteris
READY,thepowerbuttonremainscontinuouslylit.
