Ok, thank you. Will do!

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

Hello DamonCA21, I'm back at it again. Jim Hancock suggested that I speak to you about this mainboard issue I may have. Last I spoke to you I had a few things going on. I have installed in-line glass fuses to f2 and f3. I have attached a pic of what my roland versacamm sp-300v printer is doing now.

Hi that is a problem with either the transistors or the head control circuit. The head is being given the signal to turn on and off at the wrong times which is why it is overprinting in the wrong place.
I can do repairs for this if you sent the board to me

Hi damonCA21, I will send it to you once I have everything packaged. I will contact you when it's on the way after all instructions are completed. Thank you,SJ

Hi DamonCA21, I have sent my board to you this morning and payment made as requested. Thank you for your help.

Hi Jim, I have connected with Damon, will update you when he's done. Thanks for all your help.

Hello Damon, thanks for checking out my board. What components were bad on the board? SJ

 

[Lightbulb88]

Hello DamonCA21, do you have a tracking number for my board you sent? I don't know when I should expect to receive it. Thanks.

Hi Damon, I received my board. Will update once reinstalled.

Thank you,
Sj

Sorry I missed the tracking number post. Let me know how you get on. If you are still getting problems then we can look at the next things it could be

Hi Damon, I've been away for work and I'm just able to put the board back in my versacamm sp-300v. I replaced all the cables and thought I had the long cable connected to the carriage tray, but I don't. When I turned the machine on, the magenta and yellow prints beautifully, the blue and black did not print, it blew two fuses instantly. I am looking for the long cable now ‍
