The problem of print head does not flash spray is mainly due to the problem of optical fiber transmission line. As we all know, optical fiber is very easy to be damaged, it is easy to break, can not be bent. So,when we must use ,replace and plug very carefully . If the flatbed printer print head can not flash spray, we must firstly consider to plug fiber, check whether the signal is normal, can flash spray or ve? Kana yo kele mbote, landa kusadila; kana ve, nge lenda yingisa kaka nzila ya mpa ya fibre optique ya transmission. Na mambu ya mpamba, na nima ya kutula na kisika na yo, spray ya ke pela ya kuyingisa ta vanda mbote, kana ve, na nima nge fwete binga bantu yina salaka yo sambu na kulomba lusadisu ya teknike.}}.
