    I had some issues with my prints on my Roland XC-540. Cleaned the heads thoroughly and printed a test strip. NO Black printed in the test strips. So I ran some strips through versa works and Black seems to be printing OK. Ran another test print to the printer, still no black. It won't print the reg marks for the file I need to later cut either. So I'm dead in the water until I figure this out. Also FYI, the black that I am getting is not a composite black. The test print from VersaWorks prints black as well. Any Suggestions? Roland tech suggested updating firmware, which I'll do, but thats a long shot...

    The nozzle test (each dash on ink represents one nozzle) is the bottom line. There appear to be a couple of nozzles in the black head that are firing (out of 360), so that is a plus. That tends to make me think that it is a 'plumbing' issue rather than an electronics issue.

    I would replace the cap top for the K head, and attempt to draw ink from below, down toward the pump. Good luck...this requires a syringe and can get messy.

    Plenty of draw from the cap. Still no black on the test print and registers. Firmware has been updated as well...Bizarre! Also have reset the machine and unplugged it completely in hopes to reset any glitches. I'm still stumped.

    Chances are that when your printing black, it is combing colors to create the black and not using just the black ink. Possibly a bad black head? The crop marks are done with 100% black which is same as the test strips so that makes sense that neither one would print.

    Got a new print head installed and black works fine, but out of reg vertically. I have adjusted the BI-DIR to spec and the calibration. Anyone know how to adjust the angles? This is my first head replacement...Roland XC-540
