Lub tshuab luam ntawv yog dab tsi?
Lub tshuab luam ntawv yog ib qho khoom siv uas lees txais cov ntawv sau thiab cov duab kos los ntawm lub khoos phis tawj thiab hloov cov ntaub ntawv mus rau daim ntawv, feem ntau mus rau tus qauv loj, 8.5 "los ntawm 11" nplooj ntawv. Cov tshuab luam ntawv sib txawv ntawm qhov loj, ceev, sophistication thiab nqi. Feem ntau, cov tshuab luam ntawv kim dua yog siv rau kev luam ntawv ntau zaus lossis cov xim luam ntawv siab.
Lub tshuab luam ntawv tus kheej lub computer tuaj yeem paub qhov txawv raws li qhov cuam tshuam lossis tsis cuam tshuam cov tshuab luam ntawv. Cov tshuab luam ntawv cuam tshuam thaum ntxov tau ua haujlwm zoo li lub tshuab ntaus ntawv tsis siv neeg, nrog rau qhov tseem ceeb ua rau muaj kev xav zoo nkauj ntawm daim ntawv rau txhua tus cim luam tawm. Lub tshuab luam ntawv dot matrix, lub tshuab luam ntawv cuam tshuam uas ntaus ntawv ib kab ntawm ib lub sij hawm, yog ib qho kev xaiv qis qis.
Qhov zoo tshaj plaws-paub cov tshuab luam ntawv tsis cuam tshuam yog lub tshuab luam ntawv inkjet thiab lub tshuab luam ntawv laser. Lub inkjet txau tus number case los ntawm tus number case cartridge nyob ze rau ntawm daim ntawv raws li nws yob los ntawm, thaum lub tshuab luam ntawv laser siv lub laser beam reflected los ntawm daim iav kom nyiam tus number case (hu ua toner) rau cov ntawv xaiv raws li daim ntawv yob hla lub nruas. .
Ntau hom tshuab luam ntawv
Muaj ntau ntau lub tshuab luam ntawv sib txawv muaj nyob rau niaj hnub no, suav nrog Canon, Epson, Hewlett-Packard, Xerox thiab Lexmark, thiab lwm yam. Kuj tseem muaj ntau hom tshuab luam ntawv xaiv los ntawm, uas peb yuav tshawb hauv qab no.
Cov tshuab luam ntawv inkjetrov tsim cov duab digital los ntawm kev txau tus number case rau ntawm daim ntawv. Cov no yog hom ntau tshaj plaws ntawm tus kheej lub tshuab luam ntawv.
Laser tshuab luam ntawvyog siv los tsim cov ntawv luam tawm zoo los ntawm kev hla lub teeb laser ntawm kev kub ceev tshaj lub nruas tsis zoo los txhais cov duab. Xim laser printers feem ntau pom nyob rau hauv cov chaw tshaj lij.
3D tshuab luam ntawvyog ib lub tshuab luam ntawv tshiab tshiab. 3D luam ntawv tsim cov khoom siv lub cev los ntawm cov ntaub ntawv digital. Nws ua haujlwm los ntawm kev ntxiv txheej rau txheej ntawm cov khoom kom txog thaum lub tshuab luam ntawv tiav thiab cov khoom yog tag nrho.
Thermal tshuab luam ntawvtsim ib daim duab ntawm daim ntawv los ntawm kev hla daim ntawv nrog cov txheej txheem thermochromic tshaj lub taub hau luam ntawv uas muaj cov khoom siv hluav taws xob uas muaj cua sov thiab tsim cov duab nyob rau hauv qhov chaw uas cov rhuab txheej tig dub. Lub tshuab luam ntawv dye-sublimation yog ib hom thermal luam ntawv thev naus laus zis uas siv cov cua sov los hloov cov xim rau cov ntaub ntawv.
Txhua-hauv-ib lub tshuab luam ntawvyog cov khoom siv ntau yam uas sib txuas luam ntawv nrog lwm cov thev naus laus zis xws li tshuab luam ntawv, tshuab luam ntawv thiab / lossis fax tshuab.
LED tshuab luam ntawvzoo ib yam li laser printers tab sis siv lub teeb-emitting diode array nyob rau hauv lub taub hau luam es tsis txhob laser.
Cov tshuab luam ntawv duabzoo ib yam li cov tshuab luam ntawv inkjet tab sis tau tsim tshwj xeeb los luam cov duab zoo, uas yuav tsum muaj ntau tus cwj mem thiab ntawv tshwj xeeb kom paub meej tias tus number case tsis smear.
Hom tshuab luam ntawv qub
Muaj ob peb hom tshuab luam ntawv thawj zaug uas tau dhau los thiab tsis tshua siv niaj hnub no:
Dot matrix tshuab luam ntawv:Dot matrix luam ntawv yog lub tshuab luam ntawv loj tshaj plaws rau cov ntawv sau cov ntaub ntawv uas ntaus ntawv ib kab ib zaug. Dot matrix tshuab luam ntawv muab cov ntawv luam yooj yim heev.
Kab tshuab luam ntawv:Lub tshuab luam ntawv kab luam tawm ib kab ntawv ntawm ib lub sijhawm. Thaum cov ntawv luam tawm qub, cov tshuab luam ntawv kab tseem siv niaj hnub no.
Cov yam ntxwv los nrhiav hauv lub tshuab luam ntawv
Plaub lub tshuab luam ntawv zoo tshaj plaws rau cov neeg siv khoom yog:
Xim:Cov tshuab luam ntawv niaj hnub feem ntau muaj xim luam ntawv. Txawm li cas los xij, lawv tuaj yeem raug teeb tsa ua xim dub thiab dawb. Cov tshuab luam ntawv xim yog kim dua rau kev khiav lag luam vim lawv siv ob lub number case cartridges -- ib xim thiab ib tus cwj mem dub -- los yog toners uas yuav tsum tau hloov tom qab ib co nplooj ntawv luam tawm. Cov luam ntawv number case cartridges lossis toner cartridges muaj cov xim dub, cyan, magenta thiab xim daj. Tus cwj mem tuaj yeem sib xyaw ua ke, lossis nws tuaj yeem tuaj yeem sib cais monochrome khoom siv lub tshuab luam ntawv cartridges, nyob ntawm seb hom tshuab luam ntawv.
Kev daws teeb meem:Lub tshuab luam ntawv daws teeb meem -- qhov ntse ntawm cov ntawv thiab cov duab ntawm daim ntawv -- feem ntau yog ntsuas hauv dots ib nti (dpi). Feem ntau cov tshuab luam ntawv pheej yig muab kev daws teeb meem txaus rau feem ntau lub hom phiaj ntawm 600 dpi.
Ceev:Yog tias tus neeg siv luam ntawv ntau, luam ntawv ceev yog qhov tseem ceeb. Cov tshuab luam ntawv pheej yig luam tawm tsuas yog li 3 txog 6 nplooj ntawv ib feeb xwb. Txawm li cas los xij, kev luam ntawv nrawm dua yog ib qho kev xaiv nrog lub tshuab luam ntawv kim dua.
Nco:Feem ntau cov tshuab luam ntawv tuaj nrog me me ntawm lub cim xeeb -- feem ntau 2-16 megabytes- uas tuaj yeem nthuav dav los ntawm tus neeg siv. Muaj ntau tshaj qhov tsawg kawg nkaus ntawm kev nco yog pab tau thiab sai dua thaum luam tawm nplooj ntawv nrog cov duab loj.
