Roland BN-20 black missing spots

[ReliableSource19]

Hey yall,

I haven't used my BN-20 in a while since I relocated and had it crated and moved with me. At first, it was not printing anything. Then after a few cleanings the colors started coming in however their are spots missing in the black section. I have done so many cleanings and even a head wash with all the lines. I have done a head soak. I posted a picture of the types of cleanings I have done per each test print (after the head soak and wash) and it seems the powerful cleaning messed up the magenta section. When I print the color chart all the colors look good except for the dark blue and anything black has like black fuzziness around the black letters or lines. I am wondering is the printer head damaged completely? Please let me know what you think. Thanks!

When was your last cap top change,? may be well overdue?

You have deflected black nozzles and deflected and missing magenta nozzles; possibly but not probably recoverable.
Are you soaking correctly?
Power off, both captop lines clamped, fill captop, park head, let sit for 24-48 hours, run medium clean, nozzle test, any better?
do it again for 2-3 weeks, you may get lucky.
Print in High Quality, unidirectional, error diffusion, bi-cubic settings for best possible quality with damaged head.
Or, replaced head and genuine Roland dampers.
That’s all to it.
Good Luck, welcome to my world.

I just changed the cap top and the felt and rubber pieces as well before doing the head wash to see if that was the issue.

The magenta came back and is fine now. It is only the black again and the same exact spots. And no it turns out I was soaking it wrong. I need to clamp the cap top. I will try this, thank you so much that helps me a lot. Hopefully with soaking the head the correct way it will work. Appreciate it!

what is the output quality. You may just be fine, especially in High Quality
yes the two captop lines under the captop either before or after the small in-line connector. Be careful of the clamping tool you use especially if it has “teeth” like hemostats as the teeth can pierce the lines.
