2 Umgaqo-siseko womshicileli we-laser
Iprinta ye-laser sisixhobo esikhuphayo esidibanisa itekhnoloji ye-leser ye-elektroniki kunye netekhnoloji yokujonga ngombane. Abashicileli base-laser banemisebenzi eyahlukeneyo ebangelwa ziimodeli ezahlukeneyo, kodwa ulandelelwano olusebenzayo kunye nomgaqo uyafana.
Ukuthatha uMgangatho we-HP Leser Misser njengomzekelo, ulandelelwano olusebenzayo lulandelayo.
.
. Kwangelo xesha, umphezulu wedrum esecaleni ihlawuliswa sisixhobo sokutshaja. Emva koko i-laser ye-laser ngolwazigrafikhi iveliswa yinxalenye ye-laser ye-laser ukubhengeza isigubhu esifanelekileyo. Umfanekiso wama-elektrostatic usenziwe kumphezulu wedramu yetosi emva kokuvezwa.
. Xa udlula kwinkqubo yokudluliselwa, itoni idluliselwe kwiphepha phantsi kwesenzo sendawo yombane yesixhobo sokutshintshela.
. Okokugqibela, kungena kwinkqubo yokulungisa amaqondo okulungisa amaqondo obushushu, kwaye imizobo eyenziweyo kunye nesicatshulwa esenziwa yitoni idityaniswe ephepheni.
.
Zonke ezi nkqubo zisebenzayo zingasentla kufuneka zigqitywe kumanyathelo asixhenxe: ukubiza, ukuveza, ukuphuculwa, ukuhambisa, ukumiswa kwamandla, nokucoca amandla.
1>. Intlawulo
Ukwenza i-Dum Sun AbUrb i-Druner toner ngokolwazi lomzobo, isigubhu esifanelekileyo kufuneka sihlawuliswe kuqala.
Kukho iindlela ezimbini zokutshaja zabashicileli kwimarike, enye yi-corona ebiza kwaye enye ishaja i-roller yokushaja, zombini ezineempawu zazo.
I-COROY yiyona ndlela yokubiza ngokungathanga ngqo esebenzisa indawo esebenzayo yedrum yefonti njenge-electrode, kwaye ucingo olucekeceke kakhulu lubekwe kufutshane nomnye umkhombelo. Xa khupha okanye ukuprintwa, i-voltage ephezulu kakhulu isetyenziswa kwi-wire, kwaye indawo ejikeleze ucingo lenza umhlaba oqinileyo wombane. Phantsi kwesenzo secandelo lombane, i-ions kunye ne-polacy efanayo njengoko i-corona yocingo liphuma kumphezulu wedrum yefoto. Ukusukela kwi-Stonereceptor kumphezulu wedrum yefonti inesiphene esimnyama ebumnyameni, isityholo asiyi kuphuma, ngoko ke i-gubssenstoritive qhubekeka. Xa amathuba okuba akhusela kwelona nqanaba liphezulu lokwamkela, inkqubo yokuqhuba iphela. Ukungancedisi kwale ndlela yokuthabatha kukuba kulula ukuvelisa imitha kunye ne-ozone.
Ukushaja i-roller yokushaja yindlela yokubiza amagama, engafuni filtage ephezulu kakhulu kwaye inobuhlobo kwindalo. Ke ngoko, uninzi lweeprinta zeLarters zisebenzisa i-charmars ukuba ihlawule.
Makhe sithathe i-roller yokutshaja njengomzekelo wokuqonda yonke inkqubo yokusebenza yePrinta yeLarser.
Okokuqala, icandelo lesekethe eliphezulu livelisa i-voltage ephezulu, ebiza umphezulu wedrum yefoto enombane ongenamkhethe ngokusebenzisa icandelo lokutshaja. Emva kwesigubo esiyifoktha kunye ne-raller roll roller ejikelezayo ngomjikelo omnye, wonke umphezulu wedrum esecaleni kwe-pitsenstoriting ihlawuliswa ngexabiso elingelilo iyunifomu, njengoko kubonisiwe kumzobo 2-14.

2>. ukungakhuseleki
Ukuvezwa kwenziwa ngokujikeleza isigubhu esifanelekileyo, esivezwe nge-laser seam. Umphezulu we-gubsoritive gubsoctoritive ungqimba, ungqameko lwefonti lugubungela umqhubi we-Aluminium Alocy, kwaye iKosilo le-Aluminium Aloay ilawulwa.
Ungqimba oluyifoti tywina sisixhobo esiyifonti, esibonakaliswa ngokuba senza ukukhanya xa sityhilwe ngaphambi kokuvezwa. Ngaphambi kokuba iveze, intlawulo efanayo ihlawuliswa sisixhobo sokutshata, kunye nendawo enomtsalane emva kokuba i-laserensi iya kuba ngumqhubi weze-leaser kuya kuba ngumqhubi weze-hleya, ke ngoko intlawulo ikhutshelwe umhlaba ukuba yenze indawo kwiphepha lokuprinta. Indawo engadityaniswanga yiLaser isayigcina intlawulo yoqobo, yenza indawo engenanto kwiphepha lokuprinta. Kuba lo mfanekiso awubonakali, kubizwa ngokuba ngumfanekiso wamaxesha onke.
Inzwa yesayina yomqondiso nayo ifakwe kwiskena. Umsebenzi wale swensor kukuqinisekisa ukuba umgama wokuskena uyahambelana ukuze i-laser ye-laser ifakwe kumphezulu wedrum yefonti inokufezekisa eyona phumela ingcinga.
I-laser ye-laser ikhupha i-laser ye-laser ngolwazi, olukhanyisela kwi-prism ejikelezayo, kwaye i-prism ebonakalayo ibonisa i-laser ye-gubs, ngaloo ndlela icime i-pumem paum ngokuthe tyaba. Imoto ephambili iqhuba idrum yefoto ukuba ijikeleze ngokuqhubekayo ukufezekisa ukuskena okuthe nkqo kwedramu yefonti ye-ser ekhupha i-laser ekrameni. Umgaqo-siseko oboniswayo uboniswa kumzobo 2-15.

3>. uphuhliso
Uphuhliso yinkqubo yokusebenzisa umgaqo-nkqubo ophindaphindiweyo ophindaphindiweyo kunye nemveliso yesini yokuhlawula intlawulo yokuguqula umfanekiso wayo wokungabonakali kwiliso elibonakalayo kwimizobo ebonakalayo. Kukho isixhobo semagnethi embindini we-roller ye-roller (ekwabizwa ngokuba yi-roller roller, okanye i-magnetic roller emfutshane), kwaye i-magnetic roller emfutshane ye-magnet, ngoko ke itoli ye-powner inomdla embindini we-roller ye-roller ekhulayo.
Xa i-pitsestivitius drum ijikeleza indawo apho inxibelelana khona ne-roller ye-magnetic, ilungu lomphezulu wedraftitive engadibaniyo kunye netoni, kwaye ayiyi kuyifumana itoni; Ngelixa inxalenye efakwe i-laser inesipomo esifanayo nengqungquthela ngokuchaseneyo, ngokomgaqo-siseko oguqukayo kunye nesini esijongene nesondo, kwaye ibonakaliswe kwimizobo ye-laser ebonakalayo kumphezulu, njengoko kubonisiwe kumzobo 2-16.

4>. Dlulisela ukuprinta
Xa itoni idluliselwe kwindawo ekufutshane nephepha lokushicilela kunye neDrum yeFoto, kukho isixhobo esidlulayo ngasemva kwephepha ukuze sisebenzise uxinzelelo oluphezulu ngasemva kwephepha. Kungenxa yokuba i-voltage yesixhobo sokudlulisela iphezulu kune-voltage yendawo yokubonisa i-Drum yeFoto, imizobo, kunye nombhalo, kunye nombhalo obekwe yi-Toner idluliselwe kwisenzo sendawo yombane yesixhobo esitshatileyo, njengoko kubonisiwe kumzobo 2-17. Imizobo kunye nesicatshulwa ivele kumphezulu wephepha lokushicilela, njengoko kubonisiwe kumzobo 2-18.

5>. Hlula umbane
Xa umfanekiso wetoni udluliselwe kwiphepha lokuprinta, itoni igubungela kuphela umphezulu wephepha, kwaye ulwakhiwo lomfanekiso olwenziwe yitoni utshatyalali ngexesha lokuprinta. Ukuqinisekisa ukuthembeka komfanekiso weToner ngaphambi kokulungisa, emva kokudluliselwa, kuya kudlula kwisixhobo sokuphelisa. Umsebenzi wayo kukuphelisa i-polacy, yenza zonke iindleko kwaye wenze ukuba iphepha lingathathi hlangothi ukuze iphepha lingenise iyunithi yokulungisa ngokufanelekileyo kwaye iqinisekise kumzobo 2-19.

6>. Ukulungiswa
Ukufudumeza kunye nokulungisa yinkqubo yokusebenzisa uxinzelelo kunye nokufudumeza kumfanekiso weToner olwenziwe kwiphepha lokuprinta ukunyibilikisa i-torner kunye nokuntywila kwiphepha lokuprintwa ukwenza igrafu eqinileyo kumphezulu wephepha.
Icandelo eliphambili letoni yi-resin, indawo yokunyibilika yetoni imalunga ne-100°C, kunye neqondo lobushushu le-herller roller yeyunithi yokulungisa imalunga ne-180°C.
Ngexesha lenkqubo yokuprinta, xa iqondo lobushushu likaFuser lifikelela kubushushu obumiselwe kwangaphambili malunga ne-180°C Xa iphepha elifunxa i-Toner ligqitha kumsantsa phakathi kwe-roller eshushu (ekwabizwa ngokuba yiRoller engasentla) kunye ne-roller yoxinzelelo lwerabha (ekwaziwa ngokuba yi-roller roller ephantsi), inkqubo esezantsi iya kugqitywa. Iqondo lokushisa elivelisiweyo liyasivalela itolo, enyibilikisela iToner ephepheni, ngaloo ndlela senza umfanekiso oqinileyo kunye nombhalo, njengoko kubonisiwe kumzobo 2-20.
Umzobo 2-20 Umzobo weDiagram yokuLungiswa
Kuba umphezulu we-roller eshushu udibene nengqumbo ekungekho lula ukubambelela kwitoni, itoni ingayi ngqo ngqo kumphezulu weqondo lokufudumeza ngenxa yobushushu obuphakathi. Emva kokulungiswa, iphepha lokuprinta lahlulwa ngokufudumeza kukuqina komtshato kwaye kuthunyelwe ngaphandle kweprinta kwi-roller.
Inkqubo yokucoca kukukrazula itoni kwidrum yefonti engakhange idluliselwe ukusuka kumphezulu wephepha ukuya kwi-bin yenkunkuma.
Ngexesha lokudluliselwa, umfanekiso wetoni kwi-gubsous-pumestive enokudluliselwa ngokupheleleyo ephepheni. Ukuba ayicocwanga, itolor eseleyo kumphezulu wedrum yefonti iya kuthwalwa kumjikelo olandelayo wokushicilela, ukutshabalalisa umfanekiso omtsha. , ngaloo ndlela ichaphazela umgangatho wokuprinta.
Inkqubo yokucoca yenziwa ngumqukumbelo werabha, owona msebenzi wayo wokucoca isigubhu esifanelekileyo phambi komjikelo olandelayo wokuprinta i-Dumm. Kuba i-blade ye-scraper yokucoca irabha iyadinwa kwaye iguqukele, ibala lenza i-angle enqumlayo ngomphezulu wedrum yefoto. Xa i-pitsestivitius rubm ijikeleza, itoni kumphezulu ikhutshiwe kwi-bin yenkunkuma nge-scraper, njengoko kubonisiwe kumzobo 2-21 kubonisiwe.
