Kev siv cov laser nyob rau hauv cov ntaub ntawv no tso cai rau koj los ua ib tug heev ntshiab ncauj lus kom ntxaws dluab, ntawv nyeem los yog yees duab zoo uas sau raws nkaus Ii lub offset printing siv los sau cov phau ntawv thiab cov phau ntawv Magazine.

Lub ntsiab tsis muaj lub laser tshuab luam ntawv

Niaj hnub no tso tawm ib tug lossis loj npaum li cas ntawm laser printers. Nyob rau hauv thiaj li tsis mus kom poob lawm hauv no muaj ntau haiv neeg, nws yog tsim nyog los muaj tseeb raws li kev cai. Lub ntsiab tsis muaj laser tshuab luam ntawv muab cov printing ceev, cov kev daws teeb meem (duab clarity), lub tshuab luam ntawv tswj lus, tus nqi ntawm Internal nco thiab cov hom ntawm daim ntawv siv. Txij li thaum laser printers siv ib tug uas tsis yog-hu printing tshuab, lawv yog heev nyob ntsiag to, thiab ntau cov neeg uas nrhiav qhov uas tsis muaj suab nrov ib qho tseem ceeb txog kev paub thaum muaj kev yuav ib tug ntaus ntawv rau chaw ua hauj lwm siv. Laser printers yog yooj yim, piv txwv li lawv sau rau ntawm tsuas yog ib sab ntawm daim ntawv, thiab ob lub tsev - .. Lub sau rau ntawm ob sab. Lawv muaj peev xwm sau xim dluab, tiam sis feem ntau ntawm lawv yog cov monochrome. Yog li, qhov yooj yim tsis nyob rau hauv laser printers kuj muaj xws li tsis xws li suab nrov theem, tau ob mog printing thiab muaj peev xwm sau xim dluab.

Sau ceev

Laser printers yog muaj nyob rau hauv ib tug ntau ntawm cov speeds. Lub ntsiab tsis muaj laser printers xws li tej kev qhia raws li tus nqi ntawm ib tug-ib tog dluab ib feeb, nyob rau hauv cov nplooj ntawv ib feeb. Cov velocities yog muaj sib npaug mus rau ib tog kev printers, thiab nyob rau hauv ob sab sib dho ob dluab sau rau ntawm ib daim ntawv. Txij li thaum lub ob lub tsev, raws li ib tug txoj cai, yog ib tug-ib tog tshuab luam ntawv muaj peev xwm tig daim ntawv mus rau lwm yam sab, ob mog luam ceev nyob rau hauv cov nplooj ntawv ib feeb yog kwv yees li ib nrab ntawm cov kev ceev ntawm simplex tshuab luam ntawv.

Lub parameter uas qhia cov manufacturers ntawm printers, yog lub loj tshaj ceev uas muaj peev xwm muab ib tug printing mechanism. Thaum luam ib tug yooj yim nplooj ntawv nrog ib tug tsawg kawg nkaus ntawm phau ntawv los yog complex graphics, feem ntau pab kiag li lawm yuav tau qhov kev kawm tshaj tawm hais tias los ntawm lub chaw tsim tshuaj paus, txawm li cas los, txoj nplooj ntawv nrog ib tug ntau ntawm cov phau ntawv los yog complex graphics, yuav yog li load xws li (processor, uas tas cov ntaub ntawv nyob rau hauv cov duab), hais tias ib tug loj ua lub sij hawm yuav tsis pub ntaus ntawv mus rau koj khiav lag luam ntawm tag nrho cov ceev. Lub txim ntawm no yog hais tias lub printing ntawm complex cov nplooj ntawv tiag tiag sau ceev tsis pub dhau 10% ntawm nominal.

Nyob rau hauv thawj xim laser tshuab luam ntawv prints txhua lub xim yuav tsum tau ib zaug xwb pass los ntawm lub tshuab luam ntawv mechanism. Feem ntau cov xim khoom siv plaub xim, ntshav, xiav, dub thiab daj, thiab muaj peev xwm los sau ob qho tag nrho cov xim thiab dub-thiab-dawb dluab. Thaum luam nyob rau hauv cov xim, lawv ua hauj lwm ntawm ib tus nqi ntawm ib tug peb lub hlis twg ntawm lawv printing speeds nyob rau hauv monochrome. Muaj xim li hais tias tsim tau ib tug tag nrho cov xim duab rau 1 pass.

Laser printers feem ntau yog txwv kom muab zais raws li ceev. Tej printers ua hauj lwm ntawm speeds mus txog 20 nplooj ntawv ib feeb, chaw ua hauj lwm los yog desktop printers poob rau hauv lub chav 20-40 pg / min, printers ua hauj lwm pab pawg - .. 40-60- thiab loj printing presses - mus txog rau 60 cov nplooj ntawv / min. thiab ntau dua. Cov kev ceev ntawm tus ceev tshaj printers tshaj 200 p. / Min.

daim ntawv tso cai

Yog hais tias peb soj ntsuam lub ntsiab tsis muaj lub laser tshuab luam ntawv, kev daws teeb meem yog ib qho tseem ceeb qhia ntawm qhov zoo tshaj ntawm kev ua hauj lwm. Cov kev daws teeb meem sau raws nkaus Ii mus rau lub xov tooj ntawm ib tug neeg dots hais tias nws muaj peev xwm sau nyob rau hauv ib predetermined cheeb tsam. Laser printers ua ib tug duab uas siv ib tug array ntawm dots hu ua "bitmap". Niaj hnub nimno laser printers cuag ib tug daws teeb meem ntawm 1200 dots ib square. nti. Txij li thaum feem ntau ntawm cov pab kiag li lawm muaj tib lub daws teeb meem ob horizontally thiab mas, qhov no dimension yog feem ntau zog rau "dpi" (t / d), uas sib raug mus rau lub kev daws teeb meem ntawm ob lub kab rov tav thiab ntsug axis. Ib txhia ntawm qhov tseeb qauv ntawm laser printers muaj ib tug daws teeb meem 38400h600 t / d los yog 23.040.000 pixels ib square inch. Nws yog pom tseeb tias cov dua tus naj npawb, lub finer thiab xav paub ntau dua duab ntawm lub tshuab luam ntawv muaj peev xwm tsim.

technology ImageREt

Manufacturers kuj siv lwm yam duab li technology. Piv txwv li, Hewlett-Packard ImageREt system tuam txhab uas muag resizes thiab txaus ntawm cov ntsiab lus constituting cov ntawv nyeem los duab uas tso cai rau, piv txwv li, mus rau qhov chaw ib tug heev me me taw tes rau ntawm ntug ntawm lub pixel, ua cov duab ntau crisp nrog ntse ntseeg nkaws npawv contour kab. Nyob rau hauv tas li ntawd, nws:

- siv multilevel printing, uas mus cuag ib yam pixel ntxoov ntxoo tshuab luam ntawv ua ntej nws siv txoj algorithms txawv muaj nuj nqis ntawm txhua lub xim toner;

- Siv adaptive halftoning siv ib tug multi-level printing tshuab rau smooth qhov nkhaus thiab niaj hnub printing chaw loj loj, ua los yog zuj zus lawm lub zaus ntawm lub digital Halftone los ntawm kev txo los yog ua qhov kev ncua deb nruab nrab ntawm lawv;

- siv trapping - patented technology ntawm txhob txwm overlap ntawm ib xim nrog lwm los txhim kho cov duab zoo nyob rau hauv cov cheeb tsam ntawm txoj kev hloov;

- thiaj li halo - txiav tshem tawm ib tug xim los ntawm lwm yam ntug, kom txhob muaj cov overlap cheeb tsam thiab ua rau lawv tsis tshua pom;

- txiav ua kaw-voj xim calibration los ntawm pre-luam cov duab rau ib tug electrostatic siv thiab xaiv tus nqi ntawm cov toner, uas yog tsim nyog rau txhim khu kev qha thiab ruaj khov xim tu tub tu kiv.

Yees uas txhim kho qhov yooj yim tsis muaj lub laser tshuab luam ntawv, xa mus rau cov kom txoj HP technologies. Thaum lub sij hawm no tsim ob peb theem ImageREt:

• 4800 - siv nyob rau hauv ib tug series ntawm 9500, 9500mfp.

tshuab luam ntawv tswj lus

Cov lus siv nyob rau hauv lub printing apparatus yog ib tug txheej ntawm commands hais tias nws executes rau formatting ntaub ntawv uas xa los ntawm ib lub computer. Cov commands yog kev thiab txhais los ntawm lub tshuab luam ntawv. Muaj ntau ntau tswj lus: ib txhia yog tsim los rau laser printers, thiab lwm tus neeg, uas tau siv yav tas los nyob rau hauv tej yam yooj yim kiag li lawm, txhais los ntawm ib co pab kiag li lawm rau compatibility nrog cov laus software.

tswj cov lus hais txog qhov yooj yim tsis muaj laser printers, raws li feem ntau computer daim ntawv sau npe txhawb tsuas yog ib feem ntawm tag nrho cov muaj ntau haiv neeg lus. IBM mainframes thiab minicomputers muaj tswj lus los ntawm IBM. Nyob rau hauv ib Macintosh ib puag ncig, feem ntau daim ntaub ntawv siv Adobe PostScript - ib tug lag luam-standard lus rau piav txog txoj nplooj ntawv.

Tshuab luam ntawv Control Lus raug muab faib ua ob pawg. Paub qhov txawv nplooj ntawv piav qhia lus (PDL) thiab hom lus ESC-sequences. Ua ntej, raws li ib tug txoj cai, muaj ntau ntau yam thiab complex, thiab tso cai rau koj mus sau ntau nplooj ntawv thiab graphics uas haum rau tsim ib tug high-quality khoom, raws li cov kev nthuav qhia cov ntaub ntawv, kev manuals, catalogs, ntawv nthuav qhia thiab lwm tus. Cov yav tas yog siv los ntawm software pob uas tsim complex, mas formatted zis, xws li nraaj tsim cov kev pab cuam, lo lus processors, spreadsheets uas nws kim heev graphing.

Lub ntsiab drawback ntawm nplooj ntawv piav qhia hom lus yog hais tias lawv yuav tsum tau ntau yam pauv loj xam kev pab, uas ua nyob rau hauv lub PDL-hom printers cov ntaub ntawv qeeb qeeb. Nws overcomes qhov no los ntawm qhov chaw kawm ib tug ntau haib tshuab luam ntawv xws li, uas muaj feem xyuam rau cov nqi ntawm cov ntaus ntawv.

Ntawm cov PDL-lus sawv tawm:

- PostScript - lus ntawm tsev av Systems, chiv siv nyob rau hauv cov kua computers. Nws zoo dua cov lus dag nyob rau hauv ntau dua duab kev nthuav dav thiab kev ywj pheej ntawm cov sau tau los ntawm cov siv printing ntaus ntawv, thiab cov tsis muaj - yog qeeb, nce yuav tsum tau rau tus nqi ntawm lub cim xeeb thiab tsis muaj kev them nyiaj yug nyob ntau platforms.

- PCL - lus tsim nyob rau hauv lub tuam txhab Hewlett-Packard, uas nws lub ntsiab sib txawv yog siv cov tshuab luam ntawv pab tsim ib qho duab, uas thiaj li muaj qhov luaj li cas ntawm uploaded ntaub ntawv, accelerates ua thiab thiaj li printing lub sij hawm. Txawm li cas los, txawv printers yuav saib txawv, thiab cov lus tsis txaus siab nyob rau hauv lub Macintosh ib puag ncig.

nco

Lub ntsiab tsis yog laser printers thiab lub xub ntiag, hom thiab cov nyiaj ntawm lub cim xeeb siv nyob rau hauv lawv. Cov yav tas yog ib qho loj tivthaiv nyob rau hauv lub tshuab luam ntawv xws li. Nws kaw ib array ntawm cov ntsiab lus uas ntaub ntawv muaj ib tug duab, cov nqaij nyoos cov ntaub ntawv thiab lus txib uas raug xa los rau hauv lub computer, raws li zoo raws li fonts, duab thiab graphics. Cov ciaj ciam ntawm lub laser tshuab luam ntawv yog ncaj qha nyob rau tus nqi ntawm cov ua-nyob rau hauv lub cim xeeb. Qhov loj nws yog, qhov ntau cov ntaub ntawv nws muaj peev xwm yuav siv tau ib txhij.

Nyob rau hauv tas li ntawd, tus ntxiv nco tso cai sai printing, vim hais tias cov maub los yuav npaj ib bitmap duab ntawm cov nplooj ntawv, kom txog thaum lub yav dhau los print. Nws yuav tsis ua rau kom lub siab tshaj plaws kev ceev ntawm printing, lub tshuab luam ntawv yuav tsuas ua yuav mus cuag tau nws.

Muaj ntau tus kheej thiab chaw ua hauj lwm printers muaj cov khoom raws li tus qauv - nrog ib tug cia muaj peev xwm txaus rau luam lub tiaj ntawv nyeem cov ntaub ntawv. Raws li lub teeb yuav siv sij hawm ib tug tseem ceeb ib feem ntawm, tus ntaus ntawv yog tsis muaj peev xwm sawv ntawm luam loj dluab. Nyob rau hauv tas li ntawd, lub cim xeeb yuav cia ntxiv fonts, uas thiaj li muaj qhov chaw muaj rau cov dluab. Ntxiv nco yog feem ntau yuav tsum tau rau txoj kev siv, xws li graphics, presentations thiab desktop publishing. Yog li, nyob rau hauv lub laser tshuab luam ntawv yees duab chaw, ntawv cov ntaub ntawv (nws loj, tus xov tooj ntawm fonts siv, cov neeg kawm ntawv ntawm chaw thau khoom) yuav tsum tau luam, muaj ib tug tseem ceeb feem.

Nco feem ntau los ntawm ib tug Circuit Court board, uas yog ntxig rau hauv lub tshuab luam ntawv xws li. Nyob rau hauv ib co pab kiag li lawm, nws muaj tus tsim nta ntawm lub tshuab luam ntawv chaw tsim tshuaj paus, nyob rau hauv lwm tus neeg koj yuav siv tus qauv modules rau PC.

Txij li thaum lub tshuab luam ntawv xws li yog ib tug tshwj xeeb computer, nws yuav tsum tau mus saib tau cov ntaub ntawv. Me pab kiag li lawm cia ntaub ntawv nyob rau hauv lub ROM, tab sis cov neeg uas siv ntau fonts, piv txwv li, ib tug nraaj designer, tej zaum koj yuav xav tau ntxiv qhov chaw rau cov ntaub ntawv cia. Thiab ib co printers muab lub peev xwm mus cuag txhav los yog SSD-tsav. Discs peev xwm yuav ua-nyob rau hauv los yog nkag nrog nws lub hwj chim mov thiab kev cob cog rua rau lub tshuab luam ntawv cable.

daim ntawv Loj

Cov tom ntej no lo lus nug, uas yog tsa thaum xaiv ib laser tshuab luam ntawv: "Yuav ua li cas xaiv nyob ntawm seb daim ntawv?" Nyob rau hauv laser printers kheev siv lub tiaj ntawv daim ntawv. Cov nplooj ntawv loj yog muaj raws qhov loj ntawm lub tswv yim tais - lub thawv tso rau hauv daim ntawv pub mechanism. Feem ntau cov laser printers tuaj nrog cov tais ntawm standard loj, uas yog hu ua nyob rau hauv lub US Tsab ntawv (8,5h11 nti), thiab tus so ntawm lub ntiaj teb no - A4 (210 hli mmh297). Lwm yam ntawv ntau thiab tsawg pab yuav siv nrog cov tais ntawm qhov kev tsim nyog loj, me, feem ntau yog muag nyias, los yog nyob rau hauv ib tug heev txawv txawv phau ntawv pub hom. Yog li ntawd, qhov yooj yim tsis muaj xws li laser printers thiab cov hom siv nyob rau hauv cov ntaub ntawv.

Ib co ua qauv tso cai rau koj mus kho lub tais rau txawv ntawv ntau thiab tsawg. Duab laser printers vim hais tias ntawm lawv cov loj tsis tsim rau daim ntawv loj loj tshaj A4 los yog tsab ntawv. Loj printers muaj peev xwm ntawm printing rau A3 los yog 17 "x11" daim ntawv ntawm ib nrab ntawm cov nyob ceev.

Nyob rau hauv tas li ntawd rau ntawm daim ntawv, feem ntau laser printers yuav sau rau lwm yam ntaub ntawv, nrog rau nyias cov duab los qhia, stickers thiab OHP films. Nws yog tseem tau mus sau rau lub hnab ntawv siv phau ntawv pub los yog nrog ntxiv lub hnab ntawv feeder.

Tus xov tooj thiab muaj peev xwm ntawm cov tais nyob rau hauv lub luaj li cas thiab hom ntawm lub tshuab luam ntawv. Feem ntau cov tus kheej printers muaj ib tug tswv yim feeder rau 100 los xij ntawm standard daim ntawv thiab ib phau ntawv feeder. Chaw ua hauj lwm printers feem ntau muaj ob tais ntawm 250 los xij txhua. Workgroup tshuab luam ntawv nruab nrog tshwj xeeb thas nrog hluav taws xob muaj peev xwm ntawm 1,000 los xij. Loj lawm printers yuav muaj ob peb thas nrog lub cev muaj zog tsav peev xwm ntawm mus 3,500 los xij txhua.

Yooj yim thiab ob lub tsev

Muaj peev xwm duplex kuj koom qhov yooj yim tsis nyob rau hauv laser printers. Feem ntau cov desktop pab kiag li lawm yog simplex, t. E. Lawv sau rau ntawm ib sab ntawm daim ntawv. Ib txhia yog nruab nrog los tsis ua cas ob lub tsev unit, reversing ib daim ntawv ntawm daim ntawv ua ntej koj sau rau lwm sab. Pem teb yuav luag tag nrho cov printers nruab nrog ib tug ua-nyob rau hauv ob lub tsev unit. Duplex printing yog yuav tsum tau thaum ua hauj lwm cov ntaub ntawv, kev manuals, tab sis yog tsis tsim nyog rau cov kev xav tau ntawm chaw ua hauj lwm luam ntawv.

Muab ob npaug rau mog sau ib sab ntawm daim ntawv, invert nws, thiab ces sau rau ntawm lwm yam sab, piv txwv li. E. Ib daim ntawv npaum ob printing hauj lwm. Vim li no, lub luam ceev ob lub tsev printers ib nrab tog.

feem ntau yog ib tug ob lub tsev tshuab luam ntawv yog tsis yuav tsum tau rau chaw ua hauj lwm cov neeg siv, tab sis nyob rau hauv uas tsis tshua muaj mob, ob mog printing yog yuav tsum tau. Yog li ntawd, printers tau khiav lag luam nyob rau hauv "phau ntawv ob lub tsev" hom, thaum ib tug sab sau cov ntaub ntawv, thiab ces tus neeg siv manually puv daim ntawv ntawm daim ntawv thiab tseem printing. Los ntawm txhais tes ob lub tsev luam ntawv multi-page cov ntaub ntawv yog nyuab, raws li nws yuav tsum tau lub software yuav tsum tau sau txawm thiab khib cov nplooj ntawv nyias.

Duplexes feem tsawg txhim khu kev qha dua simplices li ntawv raws mechanism mechanically nyuab, thiab daim ntawv tej zaum yuav jam nyob rau hauv nws. Nyob rau hauv tas li ntawd, cov sau mechanism yog tsis ib txwm muab xa daim ntawv perpendicular, li ntawd, lub ntug ntawm cov ntawv luam daim ntawv yog tsis ib txwm thaum uas tig mus rau ntawm ntug ntawm daim ntawv. Qhov no distortion yog tshwj xeeb yog noticeable thaum muab ob npaug rau-tog printing.
