Need Help Xd-540 test print troubleshooting.

I wish I had seen this sooner... When you swapped the cables, it should have been stated that you need to swap the cables completely, meaning not just at the printhead end. If you hopefully completely swapped the cables, then you probably have a bad cable that blew the fuse. If you crisscrossed the cables, then you have blown the C group fuse. You can replace the fuse yourself, as this printer has fuse holders on the head board and Solventinkjet on here sells them. Hopefully, it only blew the fuse and didn't do any other damage. The circuitry inside the heads is completely different on the two sides, so if you crisscrossed the ribbons, all kinds of voltages and signals went to all the wrong places. Before you call a tech in, as he's likely going to tell you that you need a new head board, replace the fuse and both ribbons on that head and see what happens.

Printhead Fuse - 3.15A, 125V, Quick Blow Fuse | Solventinkjet.com

This is the fuse that protects the heads from power surges and shorts.

Roland DX4 Printhead Cable (Set of 2) | Solventinkjet.com

This is a set of DX4 ribbon cables for most Roland machines.

Check your fuse for those heads..

Ok so got my parts in and apparently didn’t click the 15” cables so ended up with 13” ones that don’t reach, but either way I replaced the fuse and fully swapped the cables to see if the problem followed the cables and it does not so I’m pretty sure it’s not the cables going to the head, but I am back to this,

What would be the next step. I do have a tech in the area that will come look at it.

It's got ot be a ink flow issue then. So....

Check line for leak.
Check Damper to make sure it's not crap (puffy and swollen or just empty)
Check manifold to make sure there isn't a crack in it. (That's the black piece on the head that the damper plugs into)
Check the cap-top (sometimes the hose on these gest coagulated ink in them like a blood clot and they don't draw ink)
Check the drain hose from the pump to the drain bottle to make sure it's clear... although this isn't one side related.
Also swap the ink cartridges. See if it's something there.


I think that's everything... at least off the top of my head.

Good luck man!
