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and,likeAuto‐Off,willreactautomatically
forprintingandmaintenancetasks.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.
