Man, I stumped. Any suggestions at all out there?I just replaced all the heads, caps, and dampers on this. But I can not get blue to print correctly. I have changed out the damper again to see if that would help. I tried adjusting the head some. It is always the same tho.. Any ideas?
Looks like something might have brushed the head face and clogged the nozzles. Try a head soak and then pull ink from the captop with a syringe.
I have tried the syringe and a head soak for a few hours. Maybe a 24hr soak?
This is my first machine so I far from an expert. I found it odd that the dropped lines are ALWAYS exactly the same on a test print. So I thought maybe I was missing something.
Are the caps you replaced Roland OEM caps? If not, try swapping the magenta and cyan caps and see what happens. Aftermarket caps are very hit and miss.
I hate to say it but the C head is probably toast even though it is new. Something damaged the face and you are not going to recover it.
Keep in mind some things about the clean. Normal Clean uses the ink in just the head, Medium Clean uses the ink in the head and the damper, Powerful Clean uses the ink in all the above and the ink lines. There isnt anything special that one does more than another, other than use more ink.
When you pull with a syringe from the Cyan cap while the head is capped, does ink flow into the syringe?
When it prints it is always the exact same lines that are dropped out.
If ink is flowing and the same nozzles don't fire, usually that means they are clogged or damaged unfortunately.
Grasping at straws here but you could try swapping the printhead cables from another head and see if it is that. 99% of the time though if a cable is bad the head wont fire or just runs wide open.
