Cov tshuab luam ntawv tso tawm hluav taws xob, tab sis feem ntau nws tsis nyob rau theem teeb meem rau tib neeg. Qhov kev txhawj xeeb tseem ceeb nrog cov tshuab luam ntawv tsis yog hluav taws xob tab sis tshuaj lom neeg ua paug, tshwj xeeb yog los ntawm cov tshuab luam ntawv laser. Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias txhua yam khoom siv hluav taws xob tso tawm qee theem ntawm hluav taws xob.
Lub toner siv nyob rau hauv lub tshuab luam ntawv yog tsim los ntawm cov pa roj carbon monoxide, tab sis ntawm resin thiab binders. Thaum lub sij hawm luam ntawv, lub toner yog yaj thiab fused rau hauv cov ntawv fibers ntawm qhov kub thiab txias. Cov resin nyob rau hauv lub toner yog oxidized rau hauv cov pa nrog ib tug pungent tsw, feem ntau hu ua "ozone." Thaum ozone muaj txiaj ntsig zoo ntawm kev tiv thaiv lub ntiaj teb los ntawm kev txo cov teeb meem ntawm hnub ci hluav taws xob, nws tsis muaj txiaj ntsig rau tib neeg lub cev. Kev cuam tshuam rau ozone tuaj yeem ua rau khaus khaus, ua rau muaj mob hawb pob, ua xua qhov ntswg, thiab ua rau kiv taub hau, ntuav, thiab lwm yam tsos mob.
Qee qhov kev hloov pauv toner muaj cov pa roj carbon dub ua cov khoom siv tseem ceeb, uas feem ntau suav nrog polycyclic aromatic hydrocarbons thiab dimethyl nitramine, ob qho tib si uas paub txog carcinogens. Cov tshuaj no raug tso tawm thaum lub sijhawm kho thiab tuaj yeem nqus tau, ua rau muaj kev phom sij rau cov neeg ua haujlwm.
Cov tshuab luam ntawv niaj hnub siv cov khoom siv hluav taws xob hauv lawv lub tshuab hluav taws xob photoconductor, uas tawm hluav taws xob tsawg heev. Cov hluav taws xob hluav taws xob los ntawm cov khoom siv hluav taws xob hauv cov tshuab luam ntawv zoo ib yam li cov khoom siv hauv tsev feem ntau thiab yuav muaj tsawg dua qhov uas tawm los ntawm lub computer lossis txawm tias lub xov tooj ntawm tes. Qhov nruab nrab, cov tshuab luam ntawv tsim tawm nruab nrab ntawm {{0}}.8 thiab 0.9 milligrays ntawm hluav taws xob. Cov tshuab luam ntawv, ntawm qhov tod tes, tsim cov qib siab dua me ntsis, feem ntau yog li ntawm 4.3 txog 5.3 milligrays, nrog qee zaus spikes rau 9-10 milligrays.
Cov hluav taws xob tawm los ntawm cov tshuab luam ntawv laser thiab tshuab luam ntawv yog tsawg heev thiab feem ntau tshwm sim thaum pib thiab luam ntawv. Cov qib hluav taws xob los ntawm cov tshuab luam ntawv feem ntau tsis muaj teeb meem rau tib neeg thiab tuaj yeem txo qis ntxiv los ntawm kev hnav khaub ncaws tiv thaiv tsim nyog. Qhov teeb meem loj dua cuam tshuam nrog cov tshuab luam ntawv yog lub toner nws tus kheej. Toner hais tuaj yeem nyuaj rau tshem tawm tag nrho ntawm lub cev thiab tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv yog tias nqus tau lossis noj.
Laser tshuab luam ntawv tau nruab nrog cov yam ntxwv kev nyab xeeb, thiab ntev npaum li lub hau npog sab nrauv tsis cuam tshuam nrog lub sijhawm ua haujlwm, tsis muaj kev pheej hmoo loj. Txawm li cas los xij, cov ntxhiab tsw uas tsim thaum lub sij hawm luam ntawv, tuaj yeem tsim teeb meem. Nws raug nquahu kom tsis txhob sawv ze ntawm lub tshuab luam ntawv thaum nws ua haujlwm thiab ua kom lub tshuab luam ntawv nyob deb ntawm lub cev. Txawm hais tias qee theem ntawm cov hluav taws xob muaj nyob hauv cov khoom siv hluav taws xob, kev ceev faj kom zoo tuaj yeem txo cov kev pheej hmoo ntawm kev noj qab haus huv tsawg.
