Cov tib neeg niaj hnub no yog tus yam ntxwv ntawm kev txhim kho sai thiab nquag ntawm cov thev naus laus zis. Nrog kev txaus ntseeg nyob hauv kev lag luam ntawm thev naus laus zis thiab khoom siv hluav taws xob, cov cuab yeej tshiab tshwm sim uas pab tau tib neeg lub neej. Ib qho ntawm cov cuab yeej no yog lub tshuab luam ntawv. Hnub no hauv peb tsab xov xwm peb yuav tham ntau ntxiv txog cov yam ntxwv thiab hom ntawm cov cuab yeej siv no.

Keeb kwm ntawm kev tsim

Feem ntau hais lus, thawj lub tshuab luam ntawv (qhov no yog lub npe raug rau lub npe nrov "tshuab luam ntawv") tau tsim los ntawm Chester Carlson. Lub cuab yeej tau tsim nyob hauv tsev. Lub hauv paus ntsiab lus ntawm thawj lub tshuab luam ntawv yog raws li hauv qab no:

• nyob rau thawj theem ntawm nws qhov kev sim, tus neeg tsim khoom tau sau hnub thiab qhov chaw ntawm kev sim ntawm ib daim ntawv iav hauv tus lej;
• tom qab ntawd nws tau txhuam cov phaj hlau nrog cov paj rwb, uas yav tas los tau npog nrog leej faj (yog li, cov phaj hlau tau dhau los ua hluav taws xob);
• tom qab ntawd lub phaj tau muab tso rau hauv qab daim iav;
• tus kws tshawb fawb tig lub teeb ci;
• Chester Carlson nchuav cov phaj hlau nrog lycopodium (hmoov ua los ntawm lycopodium spores);
• nyob rau theem kawg, tus kws sim tau nias daim ntawv waxed rau hauv phaj.

Raws li nws muab tawm, txoj kev no ua haujlwm. Nov yog li cas lub ntiaj teb thawj daim ntawv theej tau txais. Cov tshuab luam ntawv niaj hnub ua haujlwm ib yam nkaus. Ib zaug siv lycopodium hmoov tam sim no tau hloov pauv los ntawm toner. Ntawm thaj chaw ntawm Soviet Union, thawj lub tshuab luam ntawv tau tsim hauv xyoo 1953 ua tsaug rau kev ua haujlwm ntawm V. M. Fridkin. Xyoo 1966, Xerox lub tshuab luam ntawv txawv tebchaws tau tshwm sim hauv tebchaws Russia . - nws yog los ntawm lub npe ntawm lub tuam txhab no uas lub npe nrov ntawm lub tshuab luam ntawv "tshuab luam ntawv" tau ploj mus.

Cov cuab yeej tau tsim los ua cov ntawv theej ntawm cov ntawv loj, nws zam kev theej cov ntawv yuam kev thiab ua rau kom nrawm dua ntawm kev luam.

Cov yam ntxwv tseem ceeb

Cov cuab yeej sib dhos nqa nws txoj haujlwm hauv ntau theem. Cia peb ua tibzoo saib ntawm txhua tus ntawm lawv:

• lub teeb ci halogen ci ntsa iab pom thawj daim ntawv;
• lub teeb pom kev los ntawm daim ntawv tsim cov duab ntawm lub nruas (cov txheej txheem no tuaj yeem ua tsaug rau cov txheej txheem iav uas twb muaj lawm);
• cov nqi zoo thiab tsis zoo raug tsim rau ntawm lub nruas;
• Raws li cov duab theej theej tawm mus rau ntawm daim ntawv, cov khoom me me ntawm cov toner tau nqus mus rau thaj chaw tseem ceeb ntawm lub nruas;
• toner hais uas tau magnetized rau lub nruas yog pauv mus rau ib daim ntawv dawb paug ntawm daim ntawv;
• daim ntawv ntawm daim ntawv uas lub toner tau thov ua kom sov, thiab cov toner hais tau yaj thiab dhau mus rau hauv daim ntawv.

Nov yog li cas cov tshuab luam ntawv niaj hnub ua haujlwm. Txawm hais tias qhov txheej txheem no yog los ntawm nws qhov xwm txheej nyuaj thiab muaj ntau theem, nws tau ua tiav sai heev - txog 40 daim ntawv zoo ib yam tuaj yeem tsim tawm hauv 60 vib nas this (qhov tseeb ntau ntawm cov ntawv luam nyob ntawm tus qauv tshwj xeeb ntawm lub tshuab luam ntawv.). Cia peb ua tibzoo saib ntawm cov yam ntxwv tseem ceeb uas muaj nyob hauv cov tshuab luam ntawv niaj hnub no.

Luam daws teeb meem (lossis dpi)

Qhov ntsuas no muaj feem cuam tshuam ncaj qha rau pes tsawg teev teev cov ntawv theej theej tawm hauv ib nti. Qhov siab dua qhov ntsuas no yog, qhov kev luam ntawv zoo dua tus neeg siv tuaj yeem xav tau.

Nws yuav tsum nco ntsoov tias daim ntawv theej tawm, qhov tseeb, yog qhov xav tau ntawm thawj daim ntawv. Yog li, lub tshuab luam ntawv yuav tsis tuaj yeem txhim kho qhov ua tau zoo ntawm daim ntawv theej yog tias cov ntawv qub tsis zoo.

Ceev

Hais txog cov txheej txheem ntsuas ntawm tus qauv tshwj xeeb ntawm lub tshuab luam ntawv, tus neeg siv yuav tsum tau them nyiaj tshwj xeeb kom sai li cas lub cuab yeej tuaj yeem luam cov ntawv luam ntawm cov ntawv. Kev nrawm yog qhov tseem ceeb tshwj xeeb yog tias koj tab tom yuav lub tshuab luam ntawv ntawm cov khoom lag luam.

Luam ib lub voj voog

Raws li txoj cai dav dav, daim duab no yog 999 daim ntawv ib zaug. Txawm li cas los xij, nyob ntawm qhov xav tau ntawm tus neeg siv, qhov ntsuas no tuaj yeem hloov kho.

Scaling daim ntawv tseem ceeb

Cov ntawv luam ntawm lub lag luam niaj hnub no muab rau cov neeg siv muaj peev xwm teev cov ntaub ntawv nce mus txog 25% - 400%. Cov yam ntxwv zoo uas tau piav qhia saum toj no yog tus yam ntxwv ntawm txhua lub tshuab luam ntawv niaj hnub no . Nyob rau tib lub sijhawm, koj tseem tuaj yeem pom cov cuab yeej ntawm kev ua lag luam nrog kev ua haujlwm ntxiv: piv txwv li, ntawv pub mis tsis siv neeg, teeb tsa ntawm lub khoos phis tawj tus kheej, muaj peev xwm luam tawm ntawm lub xov tooj, thiab lwm yam.

Hom kev txheeb xyuas

Ntau lub tshuab luam ntawv tuaj yeem nrhiav tau ntawm lub khw niaj hnub no (piv txwv li, muaj lub tshuab luam ntawv me me, lub tshuab nqa cov ntawv nqa tau yooj yim, thiab lwm yam qauv). Txhawm rau kom yooj yim ntawm cov neeg siv, lub tshuab luam ntawv yog ib txwm faib ua 3 pawg loj.

Xim

Qhov sib txawv uas pom tseeb ntawm lub tshuab luam ntawv xim yog qhov tseeb tias lawv tuaj yeem luam cov ntawv thaum khaws cov xim qub ntawm cov ntawv thiab cov duab (piv txwv li duab, kab kos, rooj, thiab lwm yam).

Nws yuav tsum nco ntsoov ua ntej tias cov khoom siv xim muaj nqi ntau dua li dub thiab dawb.

Cov

Qhov txiaj ntsig tseem ceeb tshaj plaws ntawm cov tshuab luam ntawv digital suav nrog cov yam ntxwv hauv qab no:

• kev sib dhos zoo, tsis muaj qhov tsis tsim nyog thiab tsis tsim nyog;
• kev kub ceev ntawm kev ua haujlwm;
• ntau hom ntawv;
• kev hloov pauv ntawm kev teeb tsa;
• tsis muaj suab nrov thaum ua haujlwm, thiab lwm yam.

Feem ntau, sib piv cov ntawv luam los ntawm cov luam ntawv digital thiab analog, peb tuaj yeem xaus tias hauv thawj daim ntawv cov ntaub ntawv tau zoo dua.

Analog

Cov khoom siv sib piv tau nrov thiab xav tau ntawm cov neeg siv khoom, raws li lawv tau ua los ntawm tus nqi qis. Raws li, cov chav no muaj rau kev yuav khoom rau yuav luag txhua tus neeg (tsis hais txog nws li keeb kwm kev lag luam hauv zej zog) . Vim yog tus nqi peev nyiaj, cov ntawv theej duab sib piv tau ua rau qee qhov tsis zoo: piv txwv li, cov ntawv daws teeb meem qis.

Yuav xaiv li cas?

Hauv cov txheej txheem xaiv cov ntawv theej, koj yuav tsum tau ua tib zoo saib xyuas tshwj xeeb thiab muaj lub luag haujlwm. Ua ntej tshaj plaws, qhov no yog vim qhov tseeb tias tsis hais tus qauv, kev yuav khoom no yuav kim. Raws li, txhawm rau kom tsis txhob khuv xim koj qhov kev yuav khoom yav tom ntej, koj yuav tsum ua raws li qhov ua tau raws li qhov nws xaiv. Cov kws tshaj lij pom zoo kom coj mus rau hauv tus account ob peb yam tseem ceeb tsis.

Tsuas yog hauv cov chaw muag khoom no koj yuav muab cov khoom lag luam muaj npe, thiab tsis yog cov khoom lag luam tsis zoo. Ib qho ntxiv, hauv khw muag khoom raug cai koj tuaj yeem tig mus rau tus kws tshaj lij kev muag khoom tshwj xeeb rau kev tsim nyog thiab kev pab tshaj lij.
• Nqe . Tus nqi ntawm cov tshuab luam ntawv niaj hnub nyob ntawm ntau qhov tseem ceeb: tus qauv tshwj xeeb, cov chaw tsim khoom, cov ntsiab lus ua haujlwm, thiab lwm yam. tus nqi thiab zoo.
• Cov neeg siv tshuaj xyuas . Yog tias koj nyiam los ntawm tus qauv tshwj xeeb ntawm lub tshuab luam ntawv, tom qab ntawd koj yuav tsum tsis txhob tam sim mus yuav khoom rau nws. Ua ntej tshaj plaws, nws raug nquahu kom kawm cov neeg siv khoom tshuaj xyuas txog chav nyob - txoj hauv kev no, koj yuav pom tias cov yam ntxwv thiab cov khoom tau tshaj tawm los ntawm cov chaw tsim khoom sib raug zoo li cas.

Yuav siv li cas?

Cov cai rau kev siv lub cuab yeej yog yooj yim heev. Yog li, thawj zaug koj yuav tsum txuas lub tshuab luam ntawv mus rau lub khoos phis tawj thiab qhib lub cuab yeej. Tom qab ntawd koj yuav tsum teeb tsa tus number case cartridges thiab xyuas kom tseeb tias koj muaj hmoov txaus lossis toner. Nws tseem yog ib qho tseem ceeb los teeb tsa qhov tsis tsim nyog.

Cov lus qhia ib qib zuj zus rau kev siv lub tshuab luam ntawv muaj raws li hauv qab no:

• muab daim ntawv tso rau hauv lub tais tshwj xeeb;
• muab thawj daim ntawv tso rau ntawm lub khob iav ntawm lub tshuab luam ntawv;
• npog thawj daim ntawv nrog lub hau;
• nyem rau ntawm "Luam" khawm.

Yog li, cov txheej txheem ntawm kev siv chav tsev yog yooj yim heev, leej twg tuaj yeem lis nws.

Kho cov yam ntxwv

Qee qhov xwm txheej, hauv kev siv lub tshuab luam ntawv, ntau yam teeb meem yuav tshwm sim: piv txwv li, lub tshuab luam ntawv tsis luam ntawv, tsis qhib, thiab lwm yam. Yog li, ua ntej tshaj plaws, nws yuav tsum tau hais tias koj yuav tsum tsis txhob pib kho tus kheej yog tias lub sijhawm lav thiab kev pabcuam tseem siv tau. Hauv qhov no, koj yuav tsum hu rau qhov chaw yuav khoom ntawm lub tshuab luam ntawv kom tau txais kev pab thiab tau txais kev sab laj dawb.
