We have a Mimaki JV-3. This weekend I went to do a print and the registration marks didn't print. I stopped the print and did a couple of cleanings. Then did a print test and there was no black at all. Changed both black dampers. One is fine the other shows no difference. Any suggestions? Thanks in advance
Hi, try this in sequence:
- watch the dampers, they have to be full
- if the dampers are not full of black ink, take a siringe (without the needle) and try to pull the ink from the damper to fill it.
- if the siringe method is not working and only air is on it it means that some o-ring is not working
- if you can fill the dampers it's ok put the dampers in the printhead and try to do a fill-up
- if it don't work try to put the black damper in another printhead (not the nearest) and replace the posistion (black damper in yellow printhead and yellow damper in black printhead) and do a fill up again
- if the printhead where there are black damper prints black ink you need to try to change the cap top of the black printhead and/or the pump.
- if changing pump and cap top (with the damper in the right place) the black printhead doesn't work you have to change it
i hope this can help
