Principles of lag luam ntawm lub laser tshuab luam ntawv

Tej zaum, nws yog ib qhov nyuaj rau xav txog tej yam ib tug neeg nyob rau hauv lub tam sim no lub neej, yeej tsis tau hnov ntawm cov computers thiab peripherals rau lawv kom hnub no, cov pab kiag li lawm tau ua zoo indispensable nyob rau hauv lub neej niaj hnub no tau txais kev pab. Ib tug ntawm cov koom haum pab neeg txoj kev sai thiab yooj yim lag luam yog cov printers. Raws li ib tug txoj cai, ib tug zoo xws li cov txheej txheem yuav tsum muaj nyob rau hauv yuav luag txhua txhua chaw ua hauj lwm, tab sis rau cov domestic exploitation ntawm nws nrhiav tau npaum li cas rarer. Cuaj kaum, muaj coob tus neeg paub txog lub hav zoov ntawm cov pab kiag li lawm, tab sis tsis yog txhua tus to taub tej ntsiab cai ntawm cov lag luam ntawm lub tshuab luam ntawv.

Muaj ob lub ntsiab hom printers - inkjet thiab laser. Principles of lag luam ntawm lub laser tshuab luam ntawv, ntawm chav kawm, tsis nyiam tus cai hais txog kev lag luam ntawm lub tshuab luam ntawv inkjet, raws li ob qho tib si muaj ntau tsim. Rau hnub tim, tau txais kev pab xav kom xaiv ib tug qauv uas muaj laser printing, arguing tias ntau dua zoo. Ntawm cov hoob kawm, cov qauv muaj ib tug ntau dua tus nqi, tab sis yog hais tias muaj yog ib tug tsis tu ncua yuav tsum tau tsim high-zoo dluab, tus nqi pales rau hauv tsis tseem ceeb.

Yog li ntawd, dab tsi yog qhov hauv paus ntsiab lus ntawm ib tug laser tshuab luam ntawv? Ua ntej ntawm tag nrho cov, nws yuav tsum tau muab sau tseg hais tias lawv yog raws li nyob rau hauv lub tsim nta ntawm lub ntaus ntawv. Printing ib yam duab rau cov electrophotographic technology tshwm sim. Nws cov lus dag nyob rau hauv lub fact tias txhua taw tes rau ntawm daim ntawv yog nyob rau ntawm ib qhov chaw nyob rau hauv cov nplooj ntawv los ntawm kev hloov lub electron xwb tshwj xeeb zaj duab xis. Nws feem ntau yog muaj ib tug semiconductor muaj peev xwm hloov qhov hluav taws xob conductivity ntawm cov tawg. Cov tib technology yog kheev siv nyob rau hauv copiers.

Txawm lub hauv paus ntsiab lus ntawm ib tug laser tshuab luam ntawv, tsis muaj dab tsi yuav muaj tshwm sim tsis muaj ib yam nruas, uas yog lub ntsiab yam ntxwv caij ntawm tag nrho cov ntaus ntawv, nws yog nrog kev pab los ntawm cov kev hloov yuav siv sij hawm muab cov duab nyob rau hauv ib daim ntawv ntawm daim ntawv. Nws yog ib tug kheej kheej los ntawm cov hlau uas yog them nrog lub heev tshwj xeeb semiconductor zaj duab xis. Ua ntej ntawm tag nrho cov, qhov no nruas nto yog them nrog los yog tsis zoo ions.

Tom ntej no, siv ib tug laser lub teeb beam generated Superfine lub uas tsiv lub nruas, thaws rov los los ntawm ntau yam lo ntsiab muag thiab tsom iav. Impinging rau ntawm qhov chaw ntawm lub nruas ntswg lub teeb qhov chaw ntawm qhov chaw ntawm kev sib cuag. Lub laser feem ntau microcontroller lwm yam uas nyob hauv thiab tawm raws li tsim nyog. Feem ntau, cov duab tag rau lub nruas yuav siv sij hawm qhov chaw kab los ntawm kab. Qhov kawg ntawm kev kos duab rau ntawm ib kab, ib tug tshwj xeeb engine, kuj hu ua ib tug Stepper, me ntsis cranks nruas muaj ib lub sij hawm ntxiv hauv lub laser. Yog li, yog nyob rau hauv lub tog raj kheej nto duab uas muaj them cov ntsiab lus. Cov ntsiab lus yog alternated nrog tawm, nyob rau hauv qhov chaw nyob qhov twg yuav tsum muaj tsis muaj duab.

Nyob rau hauv lub kauj ruam tom ntej ntawm lub laser tshuab luam ntawv kev khiav hauj lwm hauv paus ntsiab lus koom nrog direct daim ntawv thov ntawm cov duab rau ntawm daim ntawv ntawv. Ua ntej no qhov chaw nyob rau hauv lub them nto ntawm lub nruas nrog rau lub toner muaj cov lus rov xwb. Nyob rau hauv cov ntaub ntawv no, lub nruas rotates maj mam mus rau lub xim tusyees faib. Ntxiv rau tig, lub tog raj kheej ntawm cov toner tso rau nws nyob rau hauv kev sib cuag nrog rau daim ntawv nto, uas number case yog kis mus rau cov ntawv.

Tom ntej no, daim ntawv yuav tsum xeem dhau ntawm ob shafts. Feem ntau, cov qaum ncej muaj ib tug high kub, thiab lub qis ncej presses lub sab sauv daim ntawv. Yog li, Number case hais yog rhuab thiab tsau rau ntawm daim ntawv nto. Nyob rau hauv lub xeem nruas yog ntxuav ntawm residual toner tshwj xeeb ntaus ntawv, thiab ces tag nrho cov ntawm nws saum npoo xwb yog thov dua.
