It seems as if you have a bad head. On the ribbon testing you did, keep the following in mind. Never criss-cross ribbons on the same head, as each side of the head connections have different functions and you can cause mainboard issues by doing that. Also, both ribbons should be plugged in at...

Did the techs do the force adjustment calibrations for the cutter? This requires a special dummy tool that replaces the blade holder and 2 different force gauges with 2 different ranges. I had a similar issue with a VG and I determined there was an issue while performing this calibration. I...

Clean the encoder strip itself with acetone and a microfiber cloth. Clean the encoder sensor by sliding a thin cloth moistened with isopropyl alcohol back and forth in the slot and dry with air pressure. Be sure the encoder strip is centered in the slot on the sensor when reinstalling the sensor.

I would suggest you replace the print head ribbons. Swapping the ribbons and blowing the other fuse pretty much narrows your issue down to those ribbons.

Reseat the head ribbon cables, at both the head side and the carriage board side. When doing so, closely examine the traces at the ends of the ribbons for any damage, replace if needed. If reseating the ribbons doesn't fix it, replace them. Please report your results so others may benefit...

Please fix the search engine to allow for short words. For example, I'm searching for XC-540 disconnecting. This messages comes up - "The following words were not included in your search because they are too short, too long, or too common: xc, 540". This restriction makes it very difficult to...

Check your caps for swelling of the inner "foam". It that is swollen and touching the bottom of the heads, they will act as a wick and do exactly what is happening. If they are after market caps, replace them with Roland OEM caps.

There is no telling what caused it. How old is the head? Sometimes they just fail. The 2 main causes of head failure are clogging and head strikes.

The captop has absolutely nothing to do with this problem. This is an electronic issue, not an ink flow issue. Based on the new info on the history of the problem, I would reassess my diagnosis to possibly being the printhead itself. Unless you are technically adept, you might want to consider...

Definitely looks like bad ribbon cables. Any head crashes ? What occurred around the time it started printing like this? You did not specify which 540i model series, i.e., SP, VP, or VS. The ribbons and heads are different on the different model ranges. The SP & VP series are easy and can be...

Any results after doing the calibrations I suggested?

It looks like your black is dropping out. If you do a test print immediately after this occurs, what does it look like. I suspect the black damper is failing. Also check the black cartridge, as they sometimes run out of ink and the empty tab doesn't come out far enough to stop the printer.

Are the caps you replaced Roland OEM caps? If not, try swapping the magenta and cyan caps and see what happens. Aftermarket caps are very hit and miss.

This is a scan alignment issue. The pinch rollers and grit rollers only control the feed or front to back alignment. I would suggest the following steps, in the given order. Initialize the Limit Aging - Feed, Scan and Cutting Linear Encoder Crop-Cut Alignment Print-Cut Alignment This will...

Try opening VersaWorks as an administrator.

On Thursday, 4-8-21, I posted a response in thread "Chromalux Sublimation Color Help" offering some guidance in profiling. I also said the OP could call me for further help if needed, as profiling discussion can get a bit complicated. There was no solicitation for business. This post was...

COLOR | Download | Roland DG Corporation Should be a full install, even though it says updater.

Check the condition of your pinch rollers, especially the outer rollers. They are a common cause of media shifting during contour cutting.

Onyx works just fine with sublimation. In my last job, I ran 12 sublimation printers profiled through Onyx, and had neutral grays and great color. Go for it!
