一、針式打印機打印原理是什么
針式打印機主要(yao)用于完(wan)成(cheng)各項單據的復寫,為用戶(hu)提供(gong)高效的服務,它的作用是噴墨打印技(ji)術和激(ji)光(guang)打印技(ji)術無法實現的,那么針式打印機的原理是什么呢(ni)?
針(zhen)(zhen)式打(da)(da)(da)印(yin)(yin)機(ji)是(shi)壓(ya)感式打(da)(da)(da)針(zhen)(zhen),通過打(da)(da)(da)印(yin)(yin)頭中的(de)針(zhen)(zhen)擊打(da)(da)(da)復(fu)寫紙(zhi),打(da)(da)(da)印(yin)(yin)時打(da)(da)(da)印(yin)(yin)針(zhen)(zhen)頭彈出,將色帶(dai)顏色打(da)(da)(da)印(yin)(yin)到紙(zhi)張上,打(da)(da)(da)印(yin)(yin)過程(cheng)中針(zhen)(zhen)頭會(hui)一直對紙(zhi)張施加壓(ya)力,可(ke)以(yi)(yi)使多(duo)層的(de)復(fu)寫紙(zhi)打(da)(da)(da)印(yin)(yin)出同(tong)樣的(de)效果,所以(yi)(yi)除了第(di)一張紙(zhi)上的(de)字跡(ji)來(lai)自于(yu)色帶(dai)的(de)油墨外,下(xia)層紙(zhi)張也會(hui)同(tong)時顯示(shi)出字跡(ji),從而實現了多(duo)聯(lian)打(da)(da)(da)印(yin)(yin)。
二、針式打印機無法打印如何解決
針式打(da)(da)印(yin)機(ji)用(yong)來打(da)(da)印(yin)各種票據(ju)、多份聯(lian)打(da)(da)是很(hen)方(fang)便(bian)的,在使用(yong)針式打(da)(da)印(yin)機(ji)的時候(hou),有(you)時會遇到無法打(da)(da)印(yin)的問題(ti)(ti),可能的故障原因有(you)很(hen)多,一(yi)般是電(dian)路問題(ti)(ti),可以采(cai)取(qu)以下方(fang)法排查故障并解決:
1、首先(xian)檢查電(dian)源電(dian)路(lu)板與(yu)主板連(lian)(lian)(lian)線(xian)(xian)是(shi)否正(zheng)確(que)連(lian)(lian)(lian)接(jie)(連(lian)(lian)(lian)線(xian)(xian)是(shi)否插反(fan)或(huo)(huo)斜接(jie)或(huo)(huo)虛接(jie)),如果電(dian)源電(dian)路(lu)板與(yu)主板連(lian)(lian)(lian)線(xian)(xian)接(jie)觸不良(liang),重(zhong)新插好連(lian)(lian)(lian)線(xian)(xian)。
2、如(ru)果(guo)電(dian)源(yuan)電(dian)路(lu)板與主(zhu)板連線(xian)(xian)(xian)正(zheng)常(chang)(chang),接(jie)著(zhu)檢查主(zhu)板與控制面(mian)板的連線(xian)(xian)(xian)是否(fou)正(zheng)常(chang)(chang),如(ru)果(guo)不(bu)正(zheng)常(chang)(chang),將連線(xian)(xian)(xian)重新連接(jie)好。
3、如果主(zhu)板(ban)與控制面板(ban)的連(lian)線正常,接著檢查電(dian)源(yuan)開(kai)關是否正常,發(fa)現電(dian)源(yuan)開(kai)關損壞,則更換(huan)電(dian)源(yuan)開(kai)關。
4、如果(guo)電(dian)(dian)源(yuan)(yuan)開(kai)關(guan)(guan)正常(chang)(chang),接(jie)著(zhu)斷(duan)開(kai)電(dian)(dian)源(yuan)(yuan)電(dian)(dian)路(lu)板與主(zhu)板的連接(jie),然后接(jie)入(ru)220V,用萬用表(biao)檢測(ce)電(dian)(dian)源(yuan)(yuan)電(dian)(dian)路(lu)板的直流輸出電(dian)(dian)壓(ya)(ya)是否(fou)(fou)正常(chang)(chang);如果(guo)電(dian)(dian)源(yuan)(yuan)電(dian)(dian)路(lu)板輸出電(dian)(dian)壓(ya)(ya)不(bu)正常(chang)(chang),則電(dian)(dian)源(yuan)(yuan)電(dian)(dian)路(lu)板損壞,檢查電(dian)(dian)源(yuan)(yuan)電(dian)(dian)路(lu)板開(kai)關(guan)(guan)是否(fou)(fou)損壞,如果(guo)損壞,更換電(dian)(dian)源(yuan)(yuan)電(dian)(dian)路(lu)板開(kai)關(guan)(guan)。
5、如果電(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)路板開關正常,接著(zhu)檢(jian)測電(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)路板中的(de)初級電(dian)(dian)(dian)路的(de)保險(xian)管(guan)F1是否熔斷(duan)。如果保險(xian)管(guan)F1熔斷(duan),檢(jian)查電(dian)(dian)(dian)源(yuan)(yuan)電(dian)(dian)(dian)路板其余電(dian)(dian)(dian)路是否存在短(duan)路問題,如果沒有(you)可以更(geng)換(huan)F1。
6、如果(guo)保(bao)險管正(zheng)常,接著(zhu)檢(jian)查(cha)電(dian)(dian)源電(dian)(dian)路板中的(de)開(kai)關管、二極管、整流橋(qiao)電(dian)(dian)路等是(shi)否正(zheng)常,如果(guo)不正(zheng)常,更換損壞的(de)元器件(jian)或電(dian)(dian)源電(dian)(dian)路板。
7、如果(guo)第4步中(zhong)測量的(de)(de)電(dian)(dian)源(yuan)輸出(chu)電(dian)(dian)壓(ya)正常,接著將電(dian)(dian)機連(lian)線、頭纜線、傳感器線從主(zhu)板(ban)上(shang)撥下(xia),只連(lian)電(dian)(dian)源(yuan)電(dian)(dian)路(lu)板(ban)線及控制(zhi)面板(ban)電(dian)(dian)纜線,然后接通電(dian)(dian)源(yuan),看控制(zhi)面板(ban)的(de)(de)電(dian)(dian)源(yuan)指(zhi)示燈是否亮,如果(guo)控制(zhi)面板(ban)電(dian)(dian)源(yuan)指(zhi)示燈顯示有(you)電(dian)(dian),說明主(zhu)板(ban)正常,問題出(chu)在外圍電(dian)(dian)氣部件。
8、外圍電氣部件的檢查首先檢測字車電機和走紙電機是否燒毀,如果燒毀,更換損壞的電機;如果字車電機和走紙電機正常,接著檢查打印頭纜線是否正常(有無磨損、斷線等造成短路),如果不正常,更換打印頭線纜;如果打印頭線纜正常,接著將打印頭取下,然后加電,看打印機是否有顯示。如果針式打印機有(you)電,說明打(da)印(yin)頭(tou)內部(bu)有(you)短路(打(da)印(yin)頭(tou)線圈、針驅動(dong)管或(huo)芯(xin)片2B短路),更換短路的部(bu)件或(huo)更換打(da)印(yin)頭(tou);如(ru)果取(qu)下打(da)印(yin)頭(tou)后(hou),故障(zhang)依(yi)舊,接著檢查傳感(gan)器,并更換短路的傳感(gan)器。
9、如(ru)(ru)果(guo)控制面板電源指(zhi)示燈無顯示,則檢查(cha)主板中的(de)芯(xin)片是否(fou)有(you)(you)(you)被(bei)燒壞(huai)(huai)的(de)痕跡(如(ru)(ru)開裂、發(fa)燙等),如(ru)(ru)果(guo)有(you)(you)(you),檢查(cha)異常(chang)的(de)芯(xin)片,如(ru)(ru)果(guo)芯(xin)片損(sun)壞(huai)(huai),更(geng)換芯(xin)片;如(ru)(ru)果(guo)沒(mei)有(you)(you)(you)被(bei)燒壞(huai)(huai)的(de)芯(xin)片,接著(zhu)測量主板上5V電源對地阻值,判斷主板是否(fou)短(duan)路(lu),如(ru)(ru)果(guo)主板短(duan)路(lu),維(wei)修或更(geng)換主板;如(ru)(ru)果(guo)主板沒(mei)有(you)(you)(you)短(duan)路(lu),接著(zhu)檢查(cha)主板中的(de)門(men)陣列(lie)電路(lu)、CPU等其他元器件(jian)是否(fou)損(sun)壞(huai)(huai),如(ru)(ru)果(guo)損(sun)壞(huai)(huai),更(geng)換損(sun)壞(huai)(huai)的(de)元器件(jian);如(ru)(ru)果(guo)主板中沒(mei)有(you)(you)(you)損(sun)壞(huai)(huai)的(de)元器件(jian),最(zui)后更(geng)換主板。
