To Jim Hill, If you run into issues with your Roland, I would be able to help. I've been working on Roland printers since the first solvent printers and I can get Roland OEM parts.

If Roland had suggested that, they would not have designed the printers with the ability to change head heights. Time for a tech who only tells you facts.

I'm not sure if you are referring to Seiko and HP solvent printers with this suggestion of unplugging cables or if your referring to other brands of printers. I would have to ask what that is supposed to accomplish, if you could explain. Powering on a printer with ribbons unplugged should only...

OK, this gives me some info. Can you post a pic of this tab in Versaworks. See the attached pic. Also, I would like to see a pic of the nozzle test print and the edges of the fill test in service mode. These pics will help me start narrowing down what the problem is. It may sound strange, but...

What media setting are you using in Versaworks, i.e., resolution, passes, etc.? If you could post a screen shot of the quality settings tab for the B&W job you are printing, that would be very helpful. The XR series printers seem to have issues printing large solid blocks of color and if you are...

If you changed the encoder sensor, be sure its position is so the encoder strip is centered in the gap in the sensor or it will eventually be damaged. I don't think the encoder sensor lights, but I could be wrong. A good test is to run the fill test in service mode. This prints each color at...

Please attach a nozzle test print. If you have absolutely nothing on the magenta/yellow head, as said by solventinkjet, then a blown fuse for sure. Besides the cables, it could be a shorted transistor on the head board or a bad head. Did anything happen before the channel loss, such as a head...

The physical head height in the printer should match the setting in the software. This may be why you're getting this message...

Are you doing a bleed-cut, i.e., cutting into the ink? If so, that is your issue with the curling edges. Read this thread for a thorough dison. https://signs101.com/threads/sticker-print-and-cut.158840/#post-1476747

All the way up and all the way down. It's a lever. It stops at the end of its travel.

Is this what you are asking about?

No, unfortunately I don't. Call me to discuss your issues, we may be able to fix it through phone support.

The lever on the left side of the print head carriage. Up for high, down for low. You will have to move it during head alignments.

You should have all the steps. See the attached 2 pdf's.

Look at my post in this thread yesterday at 9:18 am...

DO make sure your caps are clean BEFORE starting this procedure. No need to worry about how much solution is in the ink lines after you are done. The procedure takes care of priming the lines. You want to do the head wash on all 3 groups individually before doing the ink fill. After each group...

Yes, follow the prompts. Because you have 4 cartridges, you will want to do each group, i.e., A, B, C individually.

Definitely a head alignment is needed.

Your safest approach is to do it automatically, as this will minimize the possibility of damaging the heads. Are you using Roland cleaning solution or the 3rd party ink cleaning solution? If you do use the syringe approach, there are several cautions to observe. IMPORTANT - excessive negative...

Can you post a pic of the problem you are having? Also a pic of the test print. This will help immensely in guiding you to a solution.
