There appears to be some sort of electrical issue. Make sure all the connections are proper. Might also want to check the transistors on the main board to make sure they are okay.

Good afternoon, Can anyone please take a look at this pic and advise to me what may be the next course of action. I have a roland versacamm sp-300v and I got the four colors back, but the black keeps printing over top of the cyanand magenta. Don't know what to do from here. Can any please advise or any ideas? Thanks in advance....

You have some sort of electrical issue. Make sure that all the cables are plugged in correctly. Might be good to check the transistors on the main board to make sure all is good there as well.

Good morning Zoogee, transistors were good and all connections were properly connected. I blew the f3 fuse again but was able to change it out quickly because I install an inline glass fuse.

If it keeps blowing fuses, there means there is a short somewhere causing it. If you're certain all the cables are good and connected properly, my best guest is something is wrong with the main board or the head itself, but I'd probably be leaning more towards the main board. Maybe someone with a little more experience and knowledge may have a little more insight for you.
OK is definitely a mainboard problem. Your black channel is getting the signal to fire at the wrong time. This is either down to the head transistors or part of the transistor circuit ( there is more to it than just testing the transistors themselves ) or the main chip is damaged. It also looks like the black channel is very blocked.
If the fuse is blowing you also have a short somewhere in the head circuit. This could also be down to a bad head so from the look of it you have more than one issue.
I do mainboard repairs if you want it looking at properly

Thank you for your all your help. I need to honestly reevaluate my investment in this machine

Do a ribbon swap as illustrated and post a new nozzle test. Be sure to power down and unplug for 15 minutes... If it's not clear, ask...

Ok, I will try this as soon as I get home from work tonight and will post new results. Thank you!

Hello Jim, I did the power down and waited 15 min. Swapped the ribbons around as diagram instruct, and machine would not turn on to do a nozzle test.
