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...

 

[Lightbulb88]

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

 

[Lightbulb88]

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.

 

[Jim Hancock]

Please send a pic of how the ribbons are plugged into the printheads. As illustrated, the ribbon pairs are moved as a set only at the printhead end. Left ribbons go to left channels, right to right. Also check that none of the ribbon traces are damaged at both ends.

 

[Lightbulb88]

Will do tonight when I am home from work. The diagram showed to cross the ribbons, the left went to the right, and the right went to the left for the data swap, was that correct?

 

[Jim Hancock]

Yes, but do not cross over the ribbons in each pair.

 

[Lightbulb88]

Im sorry, what do you mean? I disconnected the left from the printhead and plugged it into the right printheads. Then I plugged the right side over into the left printhead. I hope I did that right. I will send those pictures when I get home from work today. Thanks again. Five folks trickum

 

[Jim Hancock]

Once I see a pic later, I can respond...

 

[Lightbulb88]

Hello, im back. Here are the pics. I now have no power, smh. Checked the fuse and none are blown.

This looks like the normal ribbon setup.
1. Did you examine the traces on both ends of the ribbons?
2. Are there any LEDs lighting up?
When doing the ribbon swap, you only do it at one end. It may be easiest to do it at the carriage board. The idea is to have the K/C channel driving the M/Y head and the M/Y channel driving the K/C head. Assuming the ribbons are fine, this helps you determine whether you have a printhead issue or an electronic circuit issue. Also, you never switch the cables on a single head, i.e., switching left and right sides on a single head. There is different internal circuitry associated with each of the two connectors on a single head. Doing this can cause damage back at the mainboard. Back to you...

It is the normal setup. The pic below is the crossover.

1. Did you examine the traces on both ends of the ribbons? I did check the ribbons. I didn't pull the of the ribbons out, just the ends on the heads.

2. Are there any LEDs lighting up? No LEDs lit

 

[Jim Hancock]

Don't power it up like that. You have crisscrossed the ribbons on each head. The ribbon pairs lay on top of each other. Look carefully at the diagram.

 

[Jim Hancock]

Start over and put the ribbons back like the way they were in the attached pic. Then see if you can power up. Also check the main power fuses where the power supplies are. If you get power then we can move on.

To clarify the ribbon swap - head 1 left ribbon goes to head 2 left connector. Head 1 right ribbon goes to head 2 right connector. Head 2 left ribbon goes to head 1 left connector. Head 2 right ribbon goes to head 1 right connector. Do not connect a left side ribbon to the right side of the head and vice versa.
