Yog tias koj tsis paub txog kev lag luam lossis kev lag luam luam ntawv, koj yuav tsum xub nkag siab tias lub taub hau luam ntawv yog dab tsi thiab lawv siv rau dab tsi. Cov tshuab luam ntawv digital tsis tsuas yog siv tus cwj mem hauv tus number case cartridge ncaj qha rau lub tshuab luam ntawv. Hloov chaw, lub taub hau luam ntawv yog siv los tshem tawm cov number case los ntawm tus number case cartridge thiab drip los yog tshuaj tsuag rau hauv xov xwm los tsim cov duab los yog cov ntawv xav tau.
Lub taub hau luam ntawv yog ib qho khoom siv nyuaj, txhua xim ntawm tus cwj mem (tsawg kawg yog cyan, daj, magenta, thiab dub) muaj cov nozzles thiab cov khoom siv hluav taws xob zoo. Lub Circuit Court xa cov teeb liab mus rau lub tshuab luam ntawv lub taub hau qhia lawv thaum twg thiab ntau npaum li cas tus number case tso tawm rau hauv xov xwm. Nyob ntawm seb hom printhead koj lub tshuab luam ntawv siv, txoj kev lawv ua qhov no tuaj yeem sib txawv heev.
Piezo printhead
Ob hom luam tawm taub hau poob tus number case rau hauv cov ntawv luam tawm, tab sis qhov zoo sib xws yuav xaus rau ntawd. Piezoelectric printheads yog nruab nrog micro-cov ntsiab lus hauv txhua lub tshuab luam ntawv. Thaum tus nqi raug siv rau cov ntsiab lus no, cov nozzles txav mus thiab tus number case poob rau hauv xov xwm. Piezoelectric cov ntsiab lus thiab cov nqi hluav taws xob ua haujlwm zoo ib yam li lub tshuab hluav taws xob qhib / tawm- tus nqi hloov pauv ntawm lub nozzle, thiab qhov tsis muaj nqi yuav raug kaw.
Piezoelectric printheads tso cai rau qib siab ntawm kev tswj hwm, tsim kom muaj cov cwj mem zoo, uas ua ke tsim cov duab ntxaws. Yog tias koj xav siv dej-raws li, UV- kho tau lossis hnyav- cov kuab tshuaj raws li, peb xav kom koj xaiv lub tshuab luam ntawv nrog lub taub hau piezoelectric.
Thermal inkjet luam ntawv taub hau
Thermal print heads use heat instead of electrical charge to "turn on" ink. The tiny resistor connected to the print nozzle is energized to heat the ink in the nozzle. The ink boils and evaporates; ink bubbles are released from the nozzle onto the print medium to create an image.
Txawm hais tias koj tuaj yeem xav txog tias cov txheej txheem no tsis tshua muaj tseeb dua li piezoelectric luam ntawv, thermal printheads tseem tuaj yeem siv rau ntau daim ntawv thov. Peb pom zoo rau hom luam ntawv lub taub hau rau textiles thiab dej-raws li inks. Yog tias koj yuav HP printheads, koj tab tom yuav thermal inkjet printheads.
