I have a Mutoh VJ 426UF. After installing a new head, I did a nozzle check and noticed only one color wasn't printing. I figured something must be wrong with the damper and tried to change it. I accidentally disconnected one of the cables while the printer was in standby. The machine made some...

After some colors stopped printing, I changed the head and dampers but I made the situation worse. No ink is printing on the nuzzle check after multiple ink charges. I noticed that the ink is not getting pulled with the syringe and there is no pressure when pulling the ink. Cartridges are new...

I have to change my printer head and I thought this is a good time to switch from 4 colors to 6 (to get the white color) but I've noticed that the head only accepts 4 dampers. Is this change possible or it needed to configure by the manufacturer to run with 6 colors? If possible, what are the...

My printer currently has 4 colors and I want to switch to a 6 color in order to be able to print white. I'm planning to change the color dampers but do I also need to change the tubes that feed them? Or just taking the color out of them through a Syringe is enough? What else should I be doing...

After replacing my printer head, the prints are not sharp anymore. It looks as if air is blown into the ink and makes spray and travel around the print area. I put back the old head and saw the same issue. So bad head is ruled out. The nuzzle check prints fine or the problem is not visible since...
