2 Ihame ryakazi rya printer ya laser
Icapa rya laser nigikoresho gisohoka gihuza tekinoroji yo gusikana hamwe nubuhanga bwo kwerekana amashusho. Mucapyi ya Laser ifite imikorere itandukanye kubera moderi zitandukanye, ariko urutonde rwakazi hamwe nihame ni bimwe.
Gufata printer zisanzwe za HP laser nkurugero, akazi gakurikirana nuburyo bukurikira.
.
. Muri icyo gihe, ubuso bwingoma yifotozi yunvikana nigikoresho cyo kwishyuza. Noneho urumuri rwa lazeri hamwe namakuru ashushanyije rwakozwe na laser yogusuzuma kugirango berekane ingoma yifotora. Ishusho ya electrostatike yihishe ikorwa hejuru yingoma ya toner nyuma yo kugaragara.
(3) Nyuma ya toner cartridge ihuye na sisitemu yiterambere, ishusho yihishe iba ibishushanyo bigaragara. Iyo unyuze muri sisitemu yo kwimura, toner yimurirwa kumpapuro munsi yumurimo wumuriro wamashanyarazi.
. Hanyuma, yinjira muri sisitemu yo hejuru yubushyuhe bwo hejuru, kandi ibishushanyo ninyandiko byakozwe na toner byinjijwe mumpapuro.

Ibikorwa byose byavuzwe haruguru bigomba kunyura munzira ndwi: kwishyuza, kwerekana, iterambere, kwimura, kurandura ingufu, gukosora, no gukora isuku.
1>. Kwishyuza
Kugira ngo ingoma yifotora ikurura toner ukurikije amakuru ashushanyije, ingoma yifotora igomba kubanza kwishyurwa.
Kuri ubu hariho uburyo bubiri bwo kwishyuza imashini zicapura ku isoko, imwe ni corona yishyuza indi ikishyuza roller yishyuza, byombi bifite ibiranga.
Kwishyuza Corona nuburyo bwo kwishyuza butaziguye bukoresha substrate yuyobora yingoma yifotora nka electrode, kandi insinga yicyuma yoroheje cyane ishyirwa hafi yingoma yifotora nkizindi electrode. Iyo wandukuye cyangwa ucapura, voltage nini cyane ikoreshwa kumurongo, kandi umwanya ukikije insinga ukora umurima w'amashanyarazi ukomeye. Munsi yumurimo wumuriro wamashanyarazi, ion zifite polarite imwe ninsinga ya corona itemba hejuru yingoma yifotozi. Kubera ko fotorepteptor hejuru yingoma ya fotosensitif ifite imbaraga nyinshi mukurwanya umwijima, amafaranga ntagitemba, bityo ubushobozi bwubuso bwingoma ya fotosensitif buzakomeza kwiyongera. Iyo ubushobozi buzamutse kubushobozi bwo kwemerwa cyane, inzira yo kwishyuza irarangira. Ikibi cyubu buryo bwo kwishyuza nuko byoroshye kubyara imirasire na ozone.
Kwishyuza roller kwishyuza nuburyo bwo kwishyuza, ntibisaba ingufu zumuriro mwinshi kandi byangiza ibidukikije. Kubwibyo, printer nyinshi za laser zikoresha imashini zishyuza kugirango zishyure.
Reka dufate kwishyuza roller yo kwishyuza nkurugero kugirango dusobanukirwe nibikorwa byose bya printer ya laser.
Ubwa mbere, igice kinini cyumuzunguruko utanga amashanyarazi menshi, yishyuza hejuru yingoma ya fotosensitif hamwe namashanyarazi mabi binyuze mumashanyarazi. Nyuma yingoma ya fotosensitivite hamwe na roller yo kwishyuza bizunguruka icyarimwe kuri cycle imwe, ubuso bwose bwingoma ya fotosensitivite bwishyuzwa hamwe nuburyo bubi, nkuko bigaragara ku gishushanyo cya 2-14.

2>. kwerekanwa
Imurikagurisha rikorwa hafi yingoma yifotora, igaragazwa nurumuri rwa laser. Ubuso bwingoma ya fotosensitivite ni igicapo gifotora, igifoto cyunvikana gitwikiriye ubuso bwumuyoboro wa aluminiyumu, kandi umuyoboro wa aluminiyumu urahagarara.
Igice cya fotosensitif ni ibikoresho byifotora, birangwa no kuyobora iyo bihuye numucyo, no kubika mbere yo kwerekana. Mbere yo kwerekanwa, kwishyuza kimwe byishyurwa nigikoresho cyo kwishyuza, kandi ahantu hakeye nyuma yo kumurikirwa na laser bizahita bihinduka umuyobozi kandi bitware hamwe numuyoboro wa aluminiyumu, bityo amafaranga arekurwa hasi kugirango akore agace kanditseho impapuro. Ahantu hatarakoreshwa na laser haracyakomeza kwishyurwa ryumwimerere, bikora ahantu hatagaragara kumpapuro. Kubera ko iyi shusho yimiterere itagaragara, yitwa ishusho ya electrostatike yihishe.
Ikimenyetso cyerekana ibimenyetso nacyo cyashyizwe muri scaneri. Imikorere yiyi sensor ni ukureba ko intera yo gusikana ihoraho kugirango urumuri rwa laser rumurikirwa hejuru yingoma ya fotosensitivite ishobora kugera ku ngaruka nziza yo gufata amashusho.
Itara rya lazeri risohora urumuri rwa lazeri hamwe namakuru yimiterere, rukamurika kuri prism izenguruka impande nyinshi zerekana ibintu, kandi prism yerekana yerekana urumuri rwa lazeri hejuru yingoma ya fotosensitif binyuze mumatsinda ya lens, bityo igasikana ingoma ifotora itambitse. Moteri nyamukuru itwara ingoma yifotora kugirango ikomeze kuzunguruka kugirango tumenye neza guhanagura ingoma ya fotosensitif na laser itanga itara. Ihame ryo kumurika ryerekanwe ku gishushanyo cya 2-15.

3>. iterambere
Iterambere ninzira yo gukoresha ihame ryo kwanga abaryamana bahuje ibitsina no gukurura ababana bahuje ibitsina kwishyuza amashanyarazi kugirango uhindure amashusho yihishe ya electrostatike atagaragara mumaso gusa mubishushanyo bigaragara. Hano hari igikoresho cya magneti hagati ya rukuruzi ya magnetiki (nanone bita iterambere rya magnetiki roller, cyangwa rukuruzi ya magnetiki mugihe gito), kandi tonier iri mumashanyarazi irimo ibintu bya magneti bishobora kwinjizwa na rukuruzi, bityo tonier igomba gukururwa na rukuruzi rwagati rwagati rwiterambere rukuruzi.
Iyo ingoma yifotora yunvikana kumwanya aho ihura na magnetiki igenda itera imbere, igice cyubuso bwingoma ya fotosensitif idakoreshwa na laser iba ifite polarite imwe na toner, kandi ntizakurura toner; mugihe igice kirabagirana na laser gifite polarite imwe na toner Ku rundi ruhande, ukurikije ihame ryo kwanga abaryamana bahuje ibitsina no guhuza ibitsina bidahuje igitsina, toner iba yinjiye hejuru yingoma yifotora aho lazeri irabagirana , hanyuma ibishushanyo mbonera bya toner bikozwe hejuru, nkuko bigaragara ku gishushanyo cya 2-16.

4>. Kwimura Icapiro
Iyo tonier yimuriwe hafi yimpapuro zicapura hamwe ningoma ifotora ibyiyumvo, hariho igikoresho cyo kohereza inyuma yimpapuro kugirango ushyire ihererekanyabubasha ryinshi inyuma yimpapuro. Kuberako imbaraga za voltage yimurwa irenze hejuru yumubyigano wahantu hagaragara ingoma ya fotosensitif, ibishushanyo, hamwe ninyandiko byakozwe na toner byimurirwa kumpapuro zicapura munsi yumuriro wamashanyarazi wigikoresho cyo kwishyuza, nkuko bigaragara mu gishushanyo cya 2-17. Ibishushanyo ninyandiko bigaragara hejuru yimpapuro zandika, nkuko bigaragara ku gishushanyo cya 2-18.

5>. Gukwirakwiza amashanyarazi
Iyo ishusho ya toner yimuriwe kumpapuro zandika, tonier itwikira gusa hejuru yimpapuro, kandi imiterere yishusho yakozwe na toner irasenywa byoroshye mugihe cyo gucapa impapuro. Kugirango umenye neza ubusugire bwa toner mbere yo gukosora, nyuma yo kwimurwa, bizanyura mubikoresho bihanagura. Igikorwa cyayo ni ugukuraho polarite, gutesha agaciro amafaranga yose no gutuma impapuro zidafite aho zibogamiye kugirango impapuro zishobore kwinjira mubice bikosora neza kandi byemeze ko ibyasohotse bisohoka Ubwiza bwibicuruzwa, bwerekanwe ku gishushanyo cya 2-19.

6>. gukosora
Gushyushya no gutunganya ni inzira yo gukoresha igitutu no gushyushya ishusho ya toner yamamajwe kumpapuro zicapura kugirango ushongeshe toner hanyuma uyishire mumpapuro zicapura kugirango ushushanye igishushanyo gihamye hejuru yimpapuro.
Igice cyingenzi cya toner ni resin, aho gushonga kwa toner ni 100°C, n'ubushyuhe bwa roller yo gushyushya igice gikosora ni 180°C.
Mugihe cyo gucapa, iyo ubushyuhe bwa fuser bugeze kubushyuhe bwateganijwe bwa 180°C iyo impapuro zikurura toner zinyuze mu cyuho kiri hagati yubushyuhe (nanone bizwi nka roller yo hejuru) hamwe na reberi yumuvuduko (bizwi kandi ko umuvuduko wo hasi, uruziga rwo hasi), inzira yo guhuza izaba irangiye. Ubushyuhe bwo hejuru butanga ubushyuhe bushyushya tonier, bushonga tonier kumpapuro, bityo bigakora ishusho ninyandiko ihamye, nkuko bigaragara ku gishushanyo cya 2-20.
Igishushanyo 2-20 Igishushanyo mbonera cyo gukosora
Kuberako ubuso bwa roller yo gushyushya busizwe hamwe nigitambaro kitoroshye kwizirika kuri toner, tonier ntishobora kwizirika hejuru yubushyuhe kubera ubushyuhe bwinshi. Nyuma yo gukosora, impapuro zo gucapa zitandukanijwe nubushyuhe bwo gutandukanya ubushyuhe bwoherejwe hanyuma zoherezwa hanze ya printer binyuze mumpapuro zigaburira impapuro.
Igikorwa cyo gukora isuku ni ugukuraho tonier ku ngoma yifotora itimuwe kuva hejuru yimpapuro kugeza kumyanda ya toner.
Mugihe cyo kwimura, ishusho ya toner kumafoto yingirakamaro ntishobora kwimurwa rwose kurupapuro. Niba idasukuwe, tonier isigaye hejuru yingoma ya fotosensitif izajyanwa mumuzingo ukurikira wo gucapa, isenya ishusho nshya. , bityo bigira ingaruka nziza ku icapiro.
Igikorwa cyo gukora isuku gikozwe na rubber scraper, umurimo wacyo ni ugusukura ingoma yifotora mbere yikurikiranya ryikurikiranya ryingoma. Kubera ko icyuma gisukura reberi gishobora kwangirika kandi cyoroshye, icyuma gikora inguni yaciwe hejuru yingoma yingoma. Iyo ingoma ya fotosensitivite izunguruka, tonier hejuru yujugunywe mumyanda ya toner na scraper, nkuko bigaragara mumashusho 2-21 yerekanwe.
