Troubleshooting
Paperstickingproblem
Generally,twoormoresheetsofpaperarefedatatime,causingtheprintertostopeatingnormallyandstop.
Thisproblemisgenerallycausedbytworeasons.Oneisthedampnessofthepaper.Thisproblemisbettersolvedbybakingthepaperandputtingitontheradiatororthemonitor,butitmustnottaketime.Toolong.Second,mostofthepaperboughtbackfromthestoreisjusttakenoutofthebox,andittakesalongtimetosqueezetoformawhole,whichispronetothisphenomenon.Thesolutionistoholdthetwoendsofthepaperwithbothhandsandrubitbackandforthbeforeloadingitintotheprinter,sothateachpieceofpaperismoved,sothatoneendofthepaperformsaneatinclinedsurface,sothattheinclinedsurfaceisplaceddownintothepapertraysothatitwillnotThestickypaperphenomenonoccursagain.
Paperjamissues
Manytimes,paperjamsarecausedbyimproperuse.Afterapaperjamoccurs,firstturnofftheprinterpower,andthendecidewhethertowithdrawthepaperfromtheoutsideorfromtheinsideaccordingtothepaperjam.Atthistime,beespeciallycarefultopreventthepaperfrombeingleftinsidetheprinter.
Usuallyinordertoavoidprinterpaperjams,youneedtopayattentiontothefollowingaspects:Beforeprinting,itisbesttocheckwhethertheprinterpanelorpaperfeedslotisequippedwitha"PaperSizeSelector"switch,Ifavailable,chooseA4orLetteraccordingtothemediasizeused,sothatthepaperisnoteasytoskewandcausepaperjamswhenentering;thethicknessofthepapershouldnotbetoothinortoothick;whenaddingpapertothepaperfeedslot,besuretofirstTakeouttheoriginalpaper,tidyitupwiththenewlyaddedpaper,andputitbackintothepaperfeedslot.Thiscanpreventtheprinterfromdrawingmultiplesheetsofpaperatatimeandcausingpaperjamswhenprinting;whetherthepaperisscatteredwhenaddingpaperAfterputtingitintothepaperslot,thismethodistopreventthepaperfromstickingtogetherduetomoistureorotherfactors,causingmultiplesheetstobeentangledandjammedwhenthepaperisfed.
Theproblemofnopaperfeeding
Generally,thepapercan’tfeedthepaperbyjusthearingtherustlingofthepaperfeedwheel,causingthecomputertoprompttheprintertobeoutofpaperandstopprinting.Ibelievethatmanyusershaveencounteredsuchproblems.Ialsoencounteredthisphenomenon.
Themainreasonforthisproblemisthattheroomistoodry.Dryingofthepaperwillcausethefrictionbetweenthepaperfeedrollerandthepapertoweaken,whichwillmakeitslipperyandunabletofeedthepaper.Theonlywaytosolvethisproblemistoincreasethehumidityintheroom,butitmustbemastered,otherwiseitwillcausethepreviousproblem.Also,payspecialattentionnottolettheprinterclosetotheradiator,letalonedirecttheelectricheatertotheprinter,especiallythequartztubedirect-injectionelectricheater,whichinadditiontocausingtheproblemofnopaperfeeding,Itwillalsocausetheinkjetheadtodryandcauseprintingfailure.

Tips
1.Intheprocessofusingcolorinkjetcartridges(herereferstothesameinkcartridges),payattentiontothebalanceduseofred,yellow,blueandotherhues.Printingpictureswithonecolorismoreimportant,becauseaslongasonecolorisusedupintheinkcartridge,eveniftheothercolorsarenotusedup,theinkjetcartridgecannotcontinuetobeused.Generallyspeaking,thehighertheresolutionoftheprintedpicture,themoreinkisused.Lightcolorsconsumelessink,andbrightredorbluecompositecolorsrequiremorethanonebasiccolortobesynthesized,andthereforeconsumemoreink.
Second,donotswitchtheprinterfrequently,becausemanytypesofprinterswillperformself-checkprocedureswhentheyareturnedon,whichwillconsumeink.Trytocollectthematerialsthatneedtobeprintedandprintthemtogether(butatthesametime,becarefulnottolettheprinterWorkingcontinuouslyfortoolong),thiswillalsosaveink.
3.Iftheintegratedinkcartridgeprintheadisdryandclogged,thefollowingmethodscanbeusedtoimproveit:
1.Immersetheprintheadpart(excludingthecircuitboard)inwarmwaterforabout10-For20minutes,letwarmwaterdissolvethedrieddye(note:keepthecircuitboarddry).
2.Puttheprintheadonafewsoftanddrypapertowels,andletthepapertowelsslowlyabsorbtheresidualmoistureandinkfromthenozzle.Pleasedonotwipetheprintheadhard.Iftheinkcartridgeneedstobeusedimmediately,youcanputitbackinthecorrectpositionintheprinter.Ifyoudonotuseittemporarily,youcanpurchaseaspecialprintheadprotectiveseat(clip)forproperstorage.Therubberpadintheprotectiveseat(clip)canblocktheairandkeepthenozzlemoistforalongtime.
3.Neverprintagainwhentheinkcartridgeisoutofink.Printingwillcausethenozzletoburnout(becauseitonlyusestheelectricnozzletoejectinkandborrowinktodissipateheat).
