Lub nruas photosensitive hauv lub tshuab luam ntawv ua lub luag haujlwm tseem ceeb heev, thiab nws yog ib qho tseem ceeb ntawm cov txheej txheem luam ntawv. Tshwj xeeb, lub luag haujlwm ntawm lub nruas rhiab tuaj yeem raug sau tseg raws li hauv qab no:
1. Tau txais cov teeb liab kho qhov muag
Lub nruas yog thawj lub luag haujlwm rau kev txais lub teeb liab ntawm lub tshuab luam ntawv lub tshuab kho qhov muag. Cov teeb liab teeb no nqa cov duab cov ntaub ntawv ntawm cov ntawv sau qub, thiab tom qab ua haujlwm kho qhov muag, lawv tau teeb pom kev rau lub nruas rhiab hauv ib daim ntawv tshwj xeeb.
2. Electrostatic latent duab yog tsim
Thaum lub teeb teeb ci ci rau ntawm lub nruas rhiab, cov khoom rhiab ntawm qhov chaw ntawm lub nruas rhiab yuav hloov. Cov khoom siv photosensitive nyob rau hauv qhov chaw raug ua hluav taws xob nyob rau hauv irradiation ntawm lub teeb, uas ua rau cov nqi xa tawm ntawm nws qhov chaw hloov pauv thiab tsim cov duab electrostatic latent sib haum nrog cov ntaub ntawv duab. Daim duab electrostatic latent no yog lub hauv paus rau tom qab toner adsorption thiab hloov duab.
3. Adsorb toner
Tom qab cov duab electrostatic latent tsim, cov cuab yeej tsim hauv lub tshuab luam ntawv xa cov toner ze ntawm lub nruas photosensitive. Vim lub electrostatic attraction, lub toner yuav adsorbed rau lub electrostatic latent duab cheeb tsam ntawm lub photosensitive nruas, tsim ib tug pom toner duab. Daim duab toner no pom tau zoo ib yam nrog cov ntaub ntawv duab hauv cov ntawv sau qub.
4. Hloov cov duab
Tom ntej no, los ntawm qhov kev txiav txim ntawm kev hloov khoom siv, cov duab toner ntawm lub nruas rhiab tau raug xa mus rau daim ntawv theej. Nyob rau hauv cov txheej txheem no, daim ntawv theej yog precisely positioned ntawm lub photosensitive nruas thiab lub hloov lwm lub tsev ntaus ntawv, thiab lub toner duab yog pauv los ntawm photosensitive nruas mus rau daim ntawv luam los ntawm kev ua ntawm ib tug hluav taws xob teb los yog siab.
5. Kho cov duab
Thaum kawg, tom qab ua tiav los ntawm kev kho cov cuab yeej, cov duab toner ntawm daim ntawv theej yog rhuab thiab khov kho kom tsim tau cov duab tas mus li. Hauv cov txheej txheem no, cov cuab yeej kho tau tso tawm qee qhov cua sov thiab lub siab, kom lub toner melts thiab nkag mus rau hauv cov fiber ntau ntawm daim ntawv luam, thiaj li ua tiav qhov kho ntawm daim duab.
