Cov tshuab luam ntawv tuaj yeem muab faib ua cov tshuab luam ntawv serial thiab cov tshuab luam ntawv sib luag raws li cov ntaub ntawv kis tau tus mob.
Raws li kev ua haujlwm ntawm lub tshuab luam ntawv, lub tshuab luam ntawv tau muab faib ua ob pawg: ntaus hom thiab tsis muaj kev cuam tshuam.
Txoj hlua dot matrix cim tsis cuam tshuam cov tshuab luam ntawv Muaj ob hom inkjet thiab thermal printers. (1) Lub tshuab luam ntawv inkjet. Lub tshuab luam ntawv siv dav tshaj plaws. Lub hauv paus ntsiab lus tseem ceeb yog tias qhov chaw them nyiaj inkjet pos huab yog deflected los ntawm electrode thiab ncaj qha ua cov ntawv xav tau ntawm daim ntawv. Qhov zoo dua yog tias cov dots uas tsim cov cim thiab cov duab me dua li cov tshuab luam ntawv dot matrix, yog li qhov kev daws teeb meem ntawm cov cim dots yog siab, thiab kev luam ntawv zoo yog siab thiab meej. Tus cwj pwm loj thiab font tuaj yeem hloov pauv tau yooj yim thiab yooj yim. Cov ntawv zoo tib yam yog siv rau kev luam ntawv, thiab lub tshuab ntaus ntawv no tuaj yeem siv los luam tawm ncaj qha rau qee yam khoom. Yog tsis muaj txhua yam hnav thiab tsim kua muag thaum tsim cov cim thiab cov duab, thiab kev siv lub zog luam tawm me me. Sau nrawm txog 500 cim / thib ob. Charge-tswj (hom high-pressure) thiab random inkjet (tsis zoo siab) inkjet tshuab yog dav siv, thiab qhuav inkjet luam ntawv tshuab tau tshwm sim. (2) Thermal tshuab luam ntawv.
Cov cua sov uas tsim los ntawm cov twj tso kua mis tam sim no ntws los ntawm qhov taw tes tsis kam ntawm lub taub hau luam ntawv yog xa mus rau cov ntawv thermal, ua rau nws thermally discolored, yog li luam tawm cov cim thiab cov duab. Cov yam ntxwv tseem ceeb yog tsis muaj suab nrov, lub teeb thiab cov qauv me me, thiab kev luam ntawv ntshiab. Qhov tsis zoo yog qeeb ceev thiab khaws tsis zoo ntawm kev sau ntawv.
Kab dot matrix cim tsis cuam tshuam cov tshuab luam ntawv feem ntau suav nrog laser, electrostatic, sib nqus thiab lub teeb-emitting diode printers. (1) Laser tshuab luam ntawv. Lub laser beam emitted los ntawm lub laser qhov chaw yog modulated los ntawm lub acousto-optic deflector tswj los ntawm cov cim dot matrix cov ntaub ntawv, nkag mus rau hauv lub kho qhov muag system, thiab scans lub rotating photoconductor nruas tom qab los ntawm ib tug multi-sided prism, thiaj li hais tias ib tug electrostatic latent duab. ib tug ua cim los yog duab yog tsim nyob rau hauv lub photoguide zaj duab xis txheej ntawm lub photoconductor nruas, thiab tom qab ntawd tom qab kev loj hlob, hloov thiab kho, yuav tsum tau tus cwj pwm los yog duab yog tau ntawm daim ntawv. Qhov txiaj ntsig tseem ceeb yog kev luam ntawv siab, uas tuaj yeem ncav cuag ntau dua 20, 000 kab ib feeb. Qhov zoo ntawm kev luam ntawv yog siab, lub suab nrov me me, cov ntawv zoo tib yam tuaj yeem siv tau, thiab cov cim, cov duab thiab cov duab tuaj yeem luam tawm. Vim yog lub siab ceev luam ntawv, macroscopically, nws zoo li luam ntawv ib nplooj ntawv ib zaug, yog li nws tseem hu ua nplooj ntawv tshuab luam ntawv. (2) Electrostatic tshuab luam ntawv. Cov mem tes voltage yog siv ncaj qha mus rau ib daim ntawv tshwj xeeb nrog ib txheej ntawm cov khoom siv dielectric thiaj li yuav tau txais cov duab electrostatic latent ntawm dielectric, uas yog tsim thiab rhuab los ua cov cim thiab cov duab. Nws yog tus cwj pwm los ntawm kev luam ntawv zoo, tsis muaj kev sau ntawv fading, khaws cia ntev, siv hluav taws xob tsawg los tsim cov duab latent, tsis muaj suab nrov, yooj yim thiab txhim khu kev qha. Txawm li cas los xij, yuav tsum muaj ntawv tshwj xeeb thiab tus nqi siab. (3) Magnetic tshuab luam ntawv. Nws yog daim ntawv thov thiab kev tsim cov tshuab luam ntawv hluav taws xob. Kev siv cov xov xwm sib nqus rhiab heev los tsim cov duab latent tsis tas yuav muaj lub zog loj laser qhov chaw, thiab nws qhov zoo dua yog tias nws tsis hnov tsw rau cov av noo thiab kub hloov. Kev luam ntawv ceev tuaj yeem ncav cuag 8000 kab / min. Cov qauv yooj yim thiab tus nqi qis. (4) Lub teeb-emitting diode tshuab luam ntawv. Ntxiv nrog rau kev siv lub teeb-emitting diodes ua lub teeb ci, nws txoj haujlwm ua haujlwm zoo ib yam li cov tshuab luam ntawv laser. Vim yog kev siv lub teeb-emitting diodes, tus nqi raug txo thiab kev siv hluav taws xob tsawg.
