Need Help Roland XC 540 CMYKLmLc

[Scotty73]

I need some help here please, before I go insane. I've purchased a Roland XC 540 about a year ago. I've put some money into it to get it up and running and into production. I've installed new heads, new capping station, new dampers, new ink pumps, pretty much every consumable that I could replace. I've done all the updates that I can see possible. Versaworks is totally up to date, and the XC 540 is at version 4.60 for firmware. The issue I am having is when I do a test print off the XC 540 it shows A as C and M, B as Y and K, C shows absolutely nothing at all. I've looked through some of the previous owners test prints in materials that I received with the XC 540, and he actually has C showing Lm and Lc. What am I missing? There has to be a simple solution to this issue.

A fuse on the head board has blown. Each group is protected by 1 fuse so if the fuse blows the whole group fails. You will need to solder a new one on or have someone do it for you. You will want to double check all of the cables before replacing the fuse to make sure it wasn't one of them that blew it in the first place.

After a quick continuity check, I can confirm that you are absolutely correct. Fortunately enough though, I seem to have fuse holder blocks in which the blown fuse can simply be popped out and the new fuse popped back in. I've also closely examined the cables and can see no damage anywhere, or anything that would give cause for concern. Thank you very much for your help VanderJ

No problem! Some people get lucky and have the newer style boards with the fuse holders. Almost all of the newer models do it this way now.

I am once again requiring your knowledge VanderJ. After inspecting the 36 pin cables, I changed the blown fuse and it immediately blew again. I have since replaced all 6 of the 36 pin cables and installed a new fuse again. It also immediately blew again. Any thoughts as to why it would do that?

Probably have a couple of cables crossed

How and why would all of a sudden I have a couple of cables crossed?

Unplug the ribbon cables from the head board, replace the fuse and turn it on. Then turn it off and check the fuse, if it is still good, your problem is in the cables, the carriage board or one of the heads. Plug components in, one at a time till the fuse blows and you'll find your problem.

Just wanted to thank and update everybody on the issue here. After some extensive bench testing, I had discovered that one of my C4131 resistors on the C heads section of my Head Board was bad. I soldered a new one into place, installed a new 3.14 A fuse, then did a test print. Bingo, we have all 6 colours printing again. Thanks again guys!
