網屏照排機FT-R5055在北(bei)方有時(shi)會出現黑線問(wen)題，尤其是(shi)(shi)在秋冬(dong)季節。這是(shi)(shi)因為北(bei)方天氣干燥，在軟片(pian)走片(pian)過程中(zhong)與各個(ge)輥子摩擦產生靜電造成的，可以(yi)按照以(yi)下(xia)步(bu)驟進行檢(jian)查：

  1．首(shou)先檢查是否為沖(chong)(chong)片(pian)(pian)(pian)機(ji)劃片(pian)(pian)(pian)子。一(yi)般定影前(qian)劃藥(yao)膜面是出(chu)(chu)黑線(xian)，定影后劃片(pian)(pian)(pian)子或定影前(qian)劃片(pian)(pian)(pian)基是出(chu)(chu)白線(xian)。將未經過照排機(ji)的軟片(pian)(pian)(pian)直接放入(ru)沖(chong)(chong)片(pian)(pian)(pian)機(ji)中沖(chong)(chong)洗，如果出(chu)(chu)黑線(xian)則表明問(wen)題出(chu)(chu)在沖(chong)(chong)片(pian)(pian)(pian)機(ji)的進片(pian)(pian)(pian)口(kou)和顯影槽(cao)內，仔(zi)細擦拭進片(pian)(pian)(pian)口(kou)，并(bing)將槽(cao)內各輥(gun)認真(zhen)清(qing)(qing)洗直至沒有黑線(xian)出(chu)(chu)現為止(zhi)（最好(hao)不(bu)要用清(qing)(qing)洗劑）。

  2．排除問(wen)題出(chu)在沖片(pian)(pian)機(ji)(ji)上后，非連線沖片(pian)(pian)機(ji)(ji)檢查收(shou)(shou)片(pian)(pian)夾是否劃片(pian)(pian)子。可將未經過照排機(ji)(ji)的(de)軟片(pian)(pian)倒入(ru)收(shou)(shou)片(pian)(pian)夾，再送(song)入(ru)沖片(pian)(pian)機(ji)(ji)內沖洗，有(you)黑線說明收(shou)(shou)片(pian)(pian)夾問(wen)題，可將收(shou)(shou)片(pian)(pian)夾上的(de)兩個螺絲擰下，打開收(shou)(shou)片(pian)(pian)夾擦拭導片(pian)(pian)輥(gun)既出(chu)片(pian)(pian)口，直到黑線消失。

  3．以上兩種情(qing)況均被(bei)排(pai)除(chu)后，需要檢(jian)查送(song)片(pian)(pian)(pian)夾。同樣(yang)可(ke)以直接拿一(yi)卷新片(pian)(pian)(pian)子，不經送(song)片(pian)(pian)(pian)夾經照排(pai)機入沖片(pian)(pian)(pian)機沖洗，沒有黑線則表(biao)明送(song)片(pian)(pian)(pian)夾劃(hua)片(pian)(pian)(pian)子，打開(kai)擦拭。

  4．最后(hou)就是照排機(ji)本身出黑線，需要擦(ca)拭所有導片輥，即檢查裁(cai)刀，此時也(ye)可聯系網屏(ping)公(gong)司國(guo)內(nei)辦事處。

  5．另外(wai)，除沖片機劃(hua)片子外(wai)，其(qi)(qi)他(ta)情況均是(shi)靜電造成，將(jiang)(jiang)室內(nei)濕度加大，就(jiu)有可能將(jiang)(jiang)問題解決，不妨試試，尤(you)其(qi)(qi)是(shi)在室內(nei)地面濕潤時黑線消失或減少(shao)，就(jiu)一(yi)定要加大室內(nei)濕度。
