I have a mutoh valuejet 1304,the black ink wasnt showing up hardly at all,so i took head out to clean it and sure enough the black was badly clogged,i soaked it overnight and flushed it through the head and all is spraying like it should now,but i put the head back in and hooked and went to do a test print of a design ive been doing and not a single color will come out,ive already drew ink out of the dampers so they are good and ready so it gotta be something else. The printer will try to print cause the head is moving back and forth like its printing something but once its stopped and i open the cover there isnt a spot of color on the material. Could it be the data cables are bad or a fuse on the mainboard cause it to not print?????
