Cov tshuab luam ntawv inkjet tuaj yeem muab faib ua cov khoom siv inkjet thiab kua inkjet ob hom (tam sim no thiab ntau dua tom qab), thaum cov kua inkjet hom tuaj yeem muab faib ua npuas hom (canon thiab hp) thiab kua piezoelectric hom (epson). Bubble technology (npuas dav hlau) yog siv los ntawm cua sov lub nozzle kom npuas tus number case thiab tshuaj tsuag rau hauv cov ntawv luam tawm. Ib yam li ntawd, hp's thermal induction inkjet thev naus laus zis (thermal inkjet thev naus laus zis) siv cov zaj duab xis nyias nyias kom sov tsawg dua 0.5 feem pua ntawm cov number case hauv cheeb tsam ejection los ua npuas. Cov npuas nthuav dav ntawm qhov ceev ceev (tsawg dua 10 microseconds), yuam cov kua dej los ntawm lub nozzle. Cov npuas txuas ntxiv loj hlob rau ob peb microseconds thiab ploj rov qab mus rau qhov resistor.
Thaum lub npuas tuag, tus number case ntawm lub nozzle retracted. Tom qab ntawd qhov nro saum npoo tsim qhov nqus thiab rub tawm tus number case tshiab los ntxiv rau qhov chaw ejection. Thermal induction inkjet thev naus laus zis yog tsim los ntawm xws li kev sib koom ua ke ntawm kev siv tshuab thev naus laus zis. Hauv piezoelectric inkjet thev naus laus zis, tus number case yog ejected los ntawm lub nozzle zoo ib yam li thermal induction inkjet thev naus laus zis, tab sis tus number case droplets yog tsim los ntawm kev txo qhov chaw ntawm tus number case ejection. Qhov txo qis ntawm qhov ejection cheeb tsam yog tswj los ntawm kev siv lub zog hluav taws xob rau ib lossis ntau dua piezoelectric daim hlau hauv thaj chaw ejection. Vim tias tus number case yog nquag hloov tshuaj ntawm qhov kub thiab txias thiab tsis ruaj khov, qhov tseeb ntawm cov xim yuav cuam tshuam rau qee yam; Ntawm qhov tod tes, vim tias tus number case yog ejected los ntawm npuas, cov kev taw qhia thiab qhov loj ntawm tus number case yog tsis yooj yim rau tuav, yog li cuam tshuam rau kev luam ntawv zoo rau qee qhov.
Micropiezoelectric tshuab luam ntawv lub taub hau tshuab siv cov yam ntxwv ntawm siv lead ua compression kom ruaj khov rau cov number case ntawm qhov kub thiab txias. Nws muaj cov yam ntxwv ntawm tus cwj pwm muaj zog poob tswj kev muaj peev xwm ntawm tus number case droplets, yooj yim kom ua tiav cov luam ntawv zoo ntawm 1440dpi nrog kev ua haujlwm siab, thiab micro-piezoelectric inkjet tsis muaj cua sov, tus number case yuav tsis dhau los ntawm cov tshuaj hloov pauv vim cua sov, yog li txo qhov yuav tsum tau ua. rau ink.
